How Can I Increment Based on the Previous Value

[Keith]

I'm a long time user of this utility and I absolutely love it! Thanks!!

I have a large batch of files, many contain the same incremental numbering:

FF_0001.jpg
FF_0001_a.jpg
FF_0001_b.jpg
FF_0002.jpg
FF_0002_a.jpg
FF_0002_b.jpg
FF_0003.jpg
FF_0003_a.jpg
FF_0003_b.jpg
etc.

Rather that just rename each file incrementally by 1, I'd like to increment each file based off the original number in cols 4-7 by, for example, 600, thus giving me:

FF_0601.jpg
FF_0601_a.jpg
FF_0601_b.jpg
FF_0602.jpg
FF_0602_a.jpg
FF_0602_b.jpg
FF_0603.jpg
FF_0603_a.jpg
FF_0603_b.jpg
etc.

I can't seem to figure out how to do it.

Is it possible??


Thanks in advance!

Hi, you could do that with javascript renaming in Special (14)
