Hi, is there any effect if we add extensions (.pdf, .docs etc) with file names inside the volume. The electronic files get stored in volume path somewhere in e00/00/00. but without any extension.

What we are trying to do is to optimize PDF and DOC files using external utility to reduce the file sizes and that utility requires extensions with filenames. That utility will just compress the files to reduce their sizes and replace them on the same location without changing names of the files.
