Kirk -
You are right: "2015-02-25-Cam02-_F9N3531.JPG" (apologies for my typo).
Hayo - I use "Better Rename 9" to rename files. The joy of PM, however, is that it is possible to create matching ingests, and avoids the possibility of operator error during a deluge of media ingesting (often at the end of a series of long days, and very sleepy).
I'll hang in there, and hope for an update. Sound reasonable?
Michael
