Can we rename a file say test.txt to test1.txt ?
If test1.txt exists will it rename ?
How do I rename it to the already existing test1.txt file so the new contents of test.txt are added to it for later use?
Copied from http://exampledepot.8waytrips.com/egs/java.io/RenameFile.html
// File (or directory) with old name
File file = new File("oldname");
// File (or directory) with new name
File file2 = new File("newname");
if (file2.exists())
throw new java.io.IOException("file exists");
// Rename file (or directory)
boolean success = file.renameTo(file2);
if (!success) {
// File was not successfully renamed
}
To append to the new file:
java.io.FileWriter out= new java.io.FileWriter(file2, true /*append=yes*/);
In short:
Files.move(source, source.resolveSibling("newname"));
More detail:
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;
The following is copied directly from http://docs.oracle.com/javase/7/docs/api/index.html:
Suppose we want to rename a file to "newname", keeping the file in the same directory:
Path source = Paths.get("path/here");
Files.move(source, source.resolveSibling("newname"));
Alternatively, suppose we want to move a file to new directory, keeping the same file name, and replacing any existing file of that name in the directory:
Path source = Paths.get("from/path");
Path newdir = Paths.get("to/path");
Files.move(source, newdir.resolve(source.getFileName()), StandardCopyOption.REPLACE_EXISTING);
You want to utilize the renameTo method on a File object.
First, create a File object to represent the destination. Check to see if that file exists. If it doesn't exist, create a new File object for the file to be moved. call the renameTo method on the file to be moved, and check the returned value from renameTo to see if the call was successful.
If you want to append the contents of one file to another, there are a number of writers available. Based on the extension, it sounds like it's plain text, so I would look at the FileWriter.
For Java 1.6 and lower, I believe the safest and cleanest API for this is Guava's Files.move.
Example:
File newFile = new File(oldFile.getParent(), "new-file-name.txt");
Files.move(oldFile.toPath(), newFile.toPath());
The first line makes sure that the location of the new file is the same directory, i.e. the parent directory of the old file.
EDIT:
I wrote this before I started using Java 7, which introduced a very similar approach. So if you're using Java 7+, you should see and upvote kr37's answer.
Renaming the file by moving it to a new name. (FileUtils is from Apache Commons IO lib)
String newFilePath = oldFile.getAbsolutePath().replace(oldFile.getName(), "") + newName;
File newFile = new File(newFilePath);
try {
FileUtils.moveFile(oldFile, newFile);
} catch (IOException e) {
e.printStackTrace();
}
This is an easy way to rename a file:
File oldfile =new File("test.txt");
File newfile =new File("test1.txt");
if(oldfile.renameTo(newfile)){
System.out.println("File renamed");
}else{
System.out.println("Sorry! the file can't be renamed");
}
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import static java.nio.file.StandardCopyOption.*;
Path yourFile = Paths.get("path_to_your_file\text.txt");
Files.move(yourFile, yourFile.resolveSibling("text1.txt"));
To replace an existing file with the name "text1.txt":
Files.move(yourFile, yourFile.resolveSibling("text1.txt"),REPLACE_EXISTING);
Try This
File file=new File("Your File");
boolean renameResult = file.renameTo(new File("New Name"));
// todo: check renameResult
Note :
We should always check the renameTo return value to make sure rename file is successful because it’s platform dependent(different Operating system, different file system) and it doesn’t throw IO exception if rename fails.
Yes, you can use File.renameTo(). But remember to have the correct path while renaming it to a new file.
import java.util.Arrays;
import java.util.List;
public class FileRenameUtility {
public static void main(String[] a) {
System.out.println("FileRenameUtility");
FileRenameUtility renameUtility = new FileRenameUtility();
renameUtility.fileRename("c:/Temp");
}
private void fileRename(String folder){
File file = new File(folder);
System.out.println("Reading this "+file.toString());
if(file.isDirectory()){
File[] files = file.listFiles();
List<File> filelist = Arrays.asList(files);
filelist.forEach(f->{
if(!f.isDirectory() && f.getName().startsWith("Old")){
System.out.println(f.getAbsolutePath());
String newName = f.getAbsolutePath().replace("Old","New");
boolean isRenamed = f.renameTo(new File(newName));
if(isRenamed)
System.out.println(String.format("Renamed this file %s to %s",f.getName(),newName));
else
System.out.println(String.format("%s file is not renamed to %s",f.getName(),newName));
}
});
}
}
}
If it's just renaming the file, you can use File.renameTo().
In the case where you want to append the contents of the second file to the first, take a look at FileOutputStream with the append constructor option or The same thing for FileWriter. You'll need to read the contents of the file to append and write them out using the output stream/writer.
As far as I know, renaming a file will not append its contents to that of an existing file with the target name.
About renaming a file in Java, see the documentation for the renameTo() method in class File.
Files.move(file.toPath(), fileNew.toPath());
works, but only when you close (or autoclose) ALL used resources (InputStream, FileOutputStream etc.) I think the same situation with file.renameTo or FileUtils.moveFile.
Here is my code to rename multiple files in a folder successfully:
public static void renameAllFilesInFolder(String folderPath, String newName, String extension) {
if(newName == null || newName.equals("")) {
System.out.println("New name cannot be null or empty");
return;
}
if(extension == null || extension.equals("")) {
System.out.println("Extension cannot be null or empty");
return;
}
File dir = new File(folderPath);
int i = 1;
if (dir.isDirectory()) { // make sure it's a directory
for (final File f : dir.listFiles()) {
try {
File newfile = new File(folderPath + "\\" + newName + "_" + i + "." + extension);
if(f.renameTo(newfile)){
System.out.println("Rename succesful: " + newName + "_" + i + "." + extension);
} else {
System.out.println("Rename failed");
}
i++;
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
and run it for an example:
renameAllFilesInFolder("E:\\Downloads\\Foldername", "my_avatar", "gif");
I do not like java.io.File.renameTo(...) because sometimes it does not renames the file and you do not know why! It just returns true of false. It does not thrown an exception if it fails.
On the other hand, java.nio.file.Files.move(...) is more useful as it throws an exception when it fails.
Running code is here.
private static void renameFile(File fileName) {
FileOutputStream fileOutputStream =null;
BufferedReader br = null;
FileReader fr = null;
String newFileName = "yourNewFileName"
try {
fileOutputStream = new FileOutputStream(newFileName);
fr = new FileReader(fileName);
br = new BufferedReader(fr);
String sCurrentLine;
while ((sCurrentLine = br.readLine()) != null) {
fileOutputStream.write(("\n"+sCurrentLine).getBytes());
}
fileOutputStream.flush();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
fileOutputStream.close();
if (br != null)
br.close();
if (fr != null)
fr.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}

The condition is if the directory exists it has to create files in that specific directory without creating a new directory.
The below code only creates a file with the new directory but not for the existing directory . For example the directory name would be like "GETDIRECTION":
String PATH = "/remote/dir/server/";
String fileName = PATH.append(id).concat(getTimeStamp()).append(".txt");
String directoryName = PATH.append(this.getClassName());
File file = new File(String.valueOf(fileName));
File directory = new File(String.valueOf(directoryName));
if (!directory.exists()) {
directory.mkdir();
if (!file.exists() && !checkEnoughDiskSpace()) {
file.getParentFile().mkdir();
file.createNewFile();
}
}
FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(value);
bw.close();
Java 8+ version:
Files.createDirectories(Paths.get("/Your/Path/Here"));
The Files.createDirectories() creates a new directory and parent directories that do not exist. This method does not throw an exception if the directory already exists.
This code checks for the existence of the directory first and creates it if not, and creates the file afterwards. Please note that I couldn't verify some of your method calls as I don't have your complete code, so I'm assuming the calls to things like getTimeStamp() and getClassName() will work. You should also do something with the possible IOException that can be thrown when using any of the java.io.* classes - either your function that writes the files should throw this exception (and it be handled elsewhere), or you should do it in the method directly. Also, I assumed that id is of type String - I don't know as your code doesn't explicitly define it. If it is something else like an int, you should probably cast it to a String before using it in the fileName as I have done here.
Also, I replaced your append calls with concat or + as I saw appropriate.
public void writeFile(String value){
String PATH = "/remote/dir/server/";
String directoryName = PATH.concat(this.getClassName());
String fileName = id + getTimeStamp() + ".txt";
File directory = new File(directoryName);
if (! directory.exists()){
directory.mkdir();
// If you require it to make the entire directory path including parents,
// use directory.mkdirs(); here instead.
}
File file = new File(directoryName + "/" + fileName);
try{
FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(value);
bw.close();
}
catch (IOException e){
e.printStackTrace();
System.exit(-1);
}
}
You should probably not use bare path names like this if you want to run the code on Microsoft Windows - I'm not sure what it will do with the / in the filenames. For full portability, you should probably use something like File.separator to construct your paths.
Edit: According to a comment by JosefScript below, it's not necessary to test for directory existence. The directory.mkdir() call will return true if it created a directory, and false if it didn't, including the case when the directory already existed.
Trying to make this as short and simple as possible. Creates directory if it doesn't exist, and then returns the desired file:
/** Creates parent directories if necessary. Then returns file */
private static File fileWithDirectoryAssurance(String directory, String filename) {
File dir = new File(directory);
if (!dir.exists()) dir.mkdirs();
return new File(directory + "/" + filename);
}
I would suggest the following for Java8+.
/**
* Creates a File if the file does not exist, or returns a
* reference to the File if it already exists.
*/
public File createOrRetrieve(final String target) throws IOException {
final File answer;
Path path = Paths.get(target);
Path parent = path.getParent();
if(parent != null && Files.notExists(parent)) {
Files.createDirectories(path);
}
if(Files.notExists(path)) {
LOG.info("Target file \"" + target + "\" will be created.");
answer = Files.createFile(path).toFile();
} else {
LOG.info("Target file \"" + target + "\" will be retrieved.");
answer = path.toFile();
}
return answer;
}
Edit: Updated to fix bug as indicated by #Cataclysm and #Marcono1234. Thx guys:)
code:
// Create Directory if not exist then Copy a file.
public static void copyFile_Directory(String origin, String destDir, String destination) throws IOException {
Path FROM = Paths.get(origin);
Path TO = Paths.get(destination);
File directory = new File(String.valueOf(destDir));
if (!directory.exists()) {
directory.mkdir();
}
//overwrite the destination file if it exists, and copy
// the file attributes, including the rwx permissions
CopyOption[] options = new CopyOption[]{
StandardCopyOption.REPLACE_EXISTING,
StandardCopyOption.COPY_ATTRIBUTES
};
Files.copy(FROM, TO, options);
}
Simple Solution using using java.nio.Path
public static Path createFileWithDir(String directory, String filename) {
File dir = new File(directory);
if (!dir.exists()) dir.mkdirs();
return Paths.get(directory + File.separatorChar + filename);
}
If you create a web based application, the better solution is to check the directory exists or not then create the file if not exist. If exists, recreate again.
private File createFile(String path, String fileName) throws IOException {
ClassLoader classLoader = getClass().getClassLoader();
File file = new File(classLoader.getResource(".").getFile() + path + fileName);
// Lets create the directory
try {
file.getParentFile().mkdir();
} catch (Exception err){
System.out.println("ERROR (Directory Create)" + err.getMessage());
}
// Lets create the file if we have credential
try {
file.createNewFile();
} catch (Exception err){
System.out.println("ERROR (File Create)" + err.getMessage());
}
return file;
}
A simple solution using Java 8
public void init(String multipartLocation) throws IOException {
File storageDirectory = new File(multipartLocation);
if (!storageDirectory.exists()) {
if (!storageDirectory.mkdir()) {
throw new IOException("Error creating directory.");
}
}
}
If you're using Java 8 or above, then Files.createDirectories() method works the best.
This question already has answers here:
To create a new directory and a file within it using Java
(2 answers)
Closed 4 years ago.
I want to write a new file inside a folder that currently does not exist.
I use it like this:
File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);
I get the file filename.txt under a folder called dir1.dir2.
I need dir1/dir2:
How can I achieve this?
Please do not mark this question as duplicate because I didn't get what I need after a reseach.
UPDATE 1
I am using Jasper Report with Spring Boot to export a pdf file.
I need to create the file under a directory name the current year. Under this folder, I need to create a directory called the current month, and under this directory the pdf file should be exported. Example :
(2018/auguest/report.pdf )
I am using LocalDateTime to get year and month
Here is a portion of my code :
ReportFiller reportFiller = context.getBean(ReportFiller.class);
reportFiller.setReportFileName("quai.jrxml");
reportFiller.compileReport();
reportFiller = context.getBean(ReportFiller.class);
reportFiller.fillReport();
ReportExporter simpleExporter = context.getBean(ReportExporter.class);
simpleExporter.setJasperPrint(reportFiller.getJasperPrint());
LocalDateTime localDateTime = LocalDateTime.now();
String dirName = simpleExporter.getPathToSaveFile() + "/"+
localDateTime.getYear() + "/" + localDateTime.getMonth().name();
File dir = new File(dirName);
dir.mkdirs();
String fileName = dirName + "/quaiReport.pdf";
simpleExporter.exportToPdf(fileName, "");
Here is what I get :
Try below code which will work as per your expectation
File dir = new File("C:\\Users\\username\\Desktop\\dir1\\dir2");
dir.mkdirs();
File file = new File(dir, "filename.txt");
FileWriter newFile = new FileWriter(file);
You need to create folder structure first and file next
You need to create directory first then create file:
Like this:
String dirName = "/" + localDateTime.getYear() + "/" + localDateTime.getMonth().name();
File file = new File(dirName);
file.mkdirs();
file = new File(file.getAbsolutePath()+"/quriReport.pdf");
file.createNewFile();
If you go your project directory you see 2018/August/quriReport.pdf
But IDE show subfolder with . if there is only one subfolder.
At first, create the directories, then create a new file to write.
import java.io.*;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
class TestDir {
public static void main(String[] args) {
String dirPath = "C:\\user\\Desktop\\dir1\\dir2\\";
String fileName = "filename.txt";
Path path = Paths.get(dirPath);
if(!Files.exists(path)) {
try {
Files.createDirectories(path);
} catch (IOException e) {
e.printStackTrace();
}
}
try (Writer writer = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(dirPath + fileName), "utf-8"))) {
writer.write("something");
} catch (IOException e) {
e.printStackTrace();
}
}
}
File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
Files.createDirectories(file.getParentFile().toPath());
FileWriter writer = new FileWriter(file);
writer.write("jora");
writer.close();
How do you move a file from one location to another? When I run my program any file created in that location automatically moves to the specified location. How do I know which file is moved?
myFile.renameTo(new File("/the/new/place/newName.file"));
File#renameTo does that (it can not only rename, but also move between directories, at least on the same file system).
Renames the file denoted by this abstract pathname.
Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. The return value should always be checked to make sure that the rename operation was successful.
If you need a more comprehensive solution (such as wanting to move the file between disks), look at Apache Commons FileUtils#moveFile
With Java 7 or newer you can use Files.move(from, to, CopyOption... options).
E.g.
Files.move(Paths.get("/foo.txt"), Paths.get("bar.txt"), StandardCopyOption.REPLACE_EXISTING);
See the Files documentation for more details
Java 6
public boolean moveFile(String sourcePath, String targetPath) {
File fileToMove = new File(sourcePath);
return fileToMove.renameTo(new File(targetPath));
}
Java 7 (Using NIO)
public boolean moveFile(String sourcePath, String targetPath) {
boolean fileMoved = true;
try {
Files.move(Paths.get(sourcePath), Paths.get(targetPath), StandardCopyOption.REPLACE_EXISTING);
} catch (Exception e) {
fileMoved = false;
e.printStackTrace();
}

I have a file which is needed for running tests - this file needs to be personalized (name and password) by whomever is running the test. I do not want to store this file in Eclipse (since it would need to be changed by whomever runs the test; also it would be storing personal info in the repo), so I have it in my home folder (/home/conrad/ssl.properties). How can I point my program to this file?
I've tried:
InputStream sslConfigStream = MyClass.class
.getClassLoader()
.getResourceAsStream("/home/" + name + "/ssl.properties");
I've also tried:
MyClass.class.getClassLoader();
InputStream sslConfigStream = ClassLoader
.getSystemResourceAsStream("/home/" + name + "/ssl.properties");
Both of these give me a RuntimeException because the sslConfigStream is null. Any help is appreciated!
Use a FileInputStream to read data from a file. The constructor takes a string path (or a File object, which encapsulates string path).
Note 1: A "resource" is a file which is in the classpath (alongside your java/class files). Since you don't want to store your file as a resource because you don't want it in your repo, ClassLoader.getSystemResourceAsStream() is not what you want.
Note 2: You should use a cross-platform way of getting a file in a home directory, as follows:
File homeDir = new File(System.getProperty("user.home"));
File propertiesFile = new File(homeDir, "ssl.properties");
InputStream sslConfigStream = new FileInputStream("/home/" + name + "/ssl.properties")
You can simplify your work, using Java's 7 method:
public static void main(String[] args) {
String fileName = "/path/to/your/file/ssl.properties";
try {
List<String> lines = Files.readAllLines(Paths.get(fileName),
Charset.defaultCharset());
for (String line : lines) {
System.out.println(line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
You can also improve your way of reading properties file, using Properties class and forget about reading and parsing your .properties file:
http://www.mkyong.com/java/java-properties-file-examples/
Is this a graphics program (ie. using the Swing library)? If so it is a pretty simple task of using a JFileChooser.
http://docs.oracle.com/javase/6/docs/api/javax/swing/JFileChooser.html
JFileChooser f = new JFileChooser();
int rval = f.showOpenDialog(this);
if (rval == JFileChooser.APPROVE_OPTION) {
// Do something with file called f
}
You can also use Scanner to read the file.
String fileContent = "";
try {
Scanner scan = new Scanner(
new File( System.getProperty("user.home")+"/ssl.properties" ));
while(scan.hasNextLine()) {
fileContent += scan.nextLine();
}
scan.close();
} catch(FileNotFoundException e) {
}
