Is a File a Subdirectory of Another Directory

[F. GEIGER]

I work with absolute paths only. I once had written classes DirName and
PathName (:= DirName + FileName) and always use them for such operations.

Within my apps I can ask questions like yours like so:
if str(anyPath.dn()).startswith(str(anyDirName)):
   print "Sorry, access restricted. "

Or w/o conv. to a string:
if anyPath.dn().startswith(anyDirName):
   print "Sorry, access restricted. "
