When my wife used CS2 she was able to have photoshop automatically update hundreds of photoshop file names with a new 3 character starter. So all the 10 character file names like this xxxxxxxxxx bbbbbbbbbb ccccccccccc would update with the same yyy as part of each file name like this yyyxxxxxxxxxx yyybbbbbbbbbb yyyccccccccccc At this point she is not able to determine how to do this same thing with CS5 and she has resorted, hopefully in the short term, to pasting the yyy into hundreds of file names. She also notices that the xxx file is over written by the bbbb file then over written by the cccc file. Any ideas on how to have photoshop of 10.6.6 update file names with the same 3 character start. Thanks.
