Program to add extensions to files?

Try tucows.com .
There are a few file utilities here of the sort your looking for.


This one, File Renamer , I have used, but I don’t know what the OSX version is like. Best of all its freeware. I can't remember much else about it, less the fact that it didn't tick me off.

If you get really desperate, separate the kind of files into folders and import them sans extensions to your WinTell computer and then using the C prompt, write a batch file or use these (1) commands with in each directory.

key _ = space character
n is the file extension you want. ie *.wav for wave files.
* is the wild card for any number of valid charcters.
(1) note- Rename is the only improtant comand.


EDIT

• 
  cls
  echo_on
  rename *.*_*.n
  exit

[Then Save]


Wow, I thought I burnt thoes nurons ages ago.

Ack, you are asking for help turning them into the dark side! *gasp*

Just copy all the files of a certain type to a single folder. Then do the rename command on all the files in the folder.

I moved my school's library system from Mac to PC back in the mid-90s, I havn't recovered from the guilt-trip yet
