How to delete the contents of the zip file but not the directory

Question

I am trying to delete the contents of zip file but not the zip directory.I tried FileUtils.cleanDirectory(deteleOldZip) , but got an error "abc.zip is not a directory".

Is there any other way to do in a single line?

Answer 1

Since you just want an empty zip file

String name = file.getAbsolutePath();
FileUtils.deleteDirectory(file)

Then create a new empty zip directory with the file path.
