renaming files 7 subfolders deep

[robodean]

So i have hundreds of files nested deep inside of subfolders I need renamed based on one of its parents folder.

SSS/
render/
ACT01/
ACT01_SQ0010/
ACT01_SQ0010_SH0010/
render/
CHAR01_lighting_compositing_primary_4f410e60-a941-4083-a00c-c49ce9cb5b2c/
v7/
sss/
sss.1001.exr
sss.1002.exr
...

I need to rename each file "sss.1001.exr" to "ACT01_SQ0010_SH0010-SSS.1001.exr"

Each ACT has a series of SEQUENCES and each SEQ has a series of shots
So this rule would have to recursively go down to the bottom-most subfolder in each of shots, and rename the files with the name of the shot as a prefix.

i hope this makes sense.

any help would be much appreciated.

Are the files always the same number of folders below the ACT folder? It might be doable but it would be quite tricky. You could try setting up a rule using nested conditions and targeting the enclosing folder to grab the name and set it as a comment, then lower folders would do the same thing but use the comment instead of the folder name to pass it down.

always the same number of folders deep!

[Mr_Noodle]

Look up nested conditions in the manual as well as subfolder processing. I think the best route is to do as I mentioned earlier and apply a parent's name to a subfolder's comment and from there, propogate that comment down. You'll need to use subfolder level to determine which rules to apply at which level. I highly recommend doing this on a copy of your files and not on the real thing as once you do any subfolder stuff, the potential to scatter things around is high.

this sounds beyond my abilities, i think.
I appreciate your help though. truly.
