How to delete files of a directory but not the folders

Question

I have create some code that deletes all the files in a folder, the issue is while this is great, I want to be able to delete all the files in a directory but leave the fold

Answer 1

simply just use File.isDirectory().

just check whether it is file or directory. if it is file then delete it otherwise leave it

in your case

if (!(myFile.isDirectory()))
{
 myFile.delete();
}

Answer 2

Why not just do

if (!myFile.isDirectory()) myFile.delete();

instead of

myFile.delete();

?

Answer 3

Recursion is overkill, as evidenced by the fact that a follow-up question was needed. See my answer there for a much simpler way:

Recursive deletion causing a stack overflow error

Answer 4

Using recursion it's very neat ;-)

private void deleteFiles(File file) {
    if (file.isDirectory())
        for (File f : file.listFiles())
            deleteFiles(f);
    else
        file.delete();
}

Answer 5

I think this will do

public void deleteFiles(File folder) throws IOException {
    List<File> files = folder.listFiles()
    foreach(File file: files){
        if(file.isFile()){
            file.delete();
        }else if(file.isDirecotry()) {
            deleteFiles(file)
        }
    }
}

Then you need to call deleteFiles(new File("D:/Documents/NetBeansProjects/printing~subversion/fileupload/web/resources/pdf/"));

Answer 6

you can use the below method.

public void deleteFiles(File folder) throws IOException {
    File[] files = folder.listFiles();
     for(File file: files){
            if(file.isFile()){
                String fileName = file.getName();
                boolean del= file.delete();
                System.out.println(fileName + " : got deleted ? " + del);
            }else if(file.isDirectory()) {
                deleteFiles(file);
            }
        }
    }
