PSCS5 – you can now replace any part of a filename with custom text . Select the files to be renamed and choose Tools > Batch Rename. Under “New Filenames” use the drop down menu to select “String Substitution” from the list. Enter in the Text to “Find” and “Replace” and voila! For example, this is an easy way to remove a prefix like “_MG_” from a file name and insert your name (or your client’s name) instead.

I tried it … I didn’t like it!
THANK YOU. This just saved my world, and helped my post-processing routine. Oh thank you!
