Hi

I have a WS which saves (and overwrites) provided xml-data to xml-files in a
certain directory under the appdir. If the file already exists it will be
overwritten only if it was originally saved/created by the ws-app. Im
wondering if there is a way to either (from code) give the app permissions
to overwrite any files in its own subdirectories?... or a way to establish
if a file was created by this app or not (if the app has write permissions
or not)? (so that a copy can be made)

Thanks!
