Thanks for all your help everyone! I made a copy of my data and did the rename on the copied version just in case I messed something up. But, everything looks good!

I did notice that there are a few other files that have different extensions in the same folder. Two of the files are in there with a COA extension and a 375 extension so I assume I can't do the rename thing. The third file has a completely different extension (LD4). Can you tell me what the following files are and if I should just delete them? ADSPROF, EZSEMTAB, and EZSSILCK.

Thanks,
Laura
