Question

TrueVFS is unable to remove the file after unmount and throws the following exception.

    java.nio.file.DirectoryNotEmptyException: tar:file:/D:/tmp/0554de32-5a95-4b58-a05d-d12effa68abc.tar!/

The tar file is successfully created, so no issues with that.

Here is what I am doing.

1. Configure the True VFS

   TConfig config = TConfig.current();
   config.setArchiveDetector(new TArchiveDetector(“tar”, new TarDriver()));

2. Create the tar

3. Unmount the tar

   TVFS.umount(tarFile);

   convert into bytes and send it.

4. Remove the file

   tarFile.rm()

I also tried tarFile.rm_r() and plain java.io.File.delete(). But none of them are working.

Can some one please advice me what went wrong? Thanks in advance.

Answer 1

TrueVFS abstracts the TAR file into a virtual directory, so you can only remove it if it’s empty. To recursively remove a (virtual) directory with all its members, just call TFile.rm_r(). You said you tried that, but maybe there was a side effect of your previous attempts, so I suggest to repeat it and see how far it gets you.
