Delete all files in directory (but not directory) - one liner solution

Question

I want to delete all files inside ABC directory.

When I tried with FileUtils.deleteDirectory(new File(\"C:/test/ABC/\")); it also deletes folder ABC.

Answer 1

Do you mean like?

for(File file: dir.listFiles()) 
    if (!file.isDirectory()) 
        file.delete();

This will only delete files, not directories.
