renaming marked/unmarked subfolder level 3+

[seanprice]

Hello forum! I didn't quite understand how I can do the following with this great tool for batch renaming.
#1
Rename 3rd subfolder {subf3} and beyond to keep only the first 4 characters of its original name?
c:\{rootf} \ {subf1} \ {subf2} \ {subf3} \ {subf4} \ {subf5}

original:
c:\long pathR \ long path1 \ long path2 \ long path3 \ long path4 \ long path5
result:
c:\long pathR \ long path1 \ long path2 \ long \ long \ long

#2
Perform subfolder rename as defined in #1 for all {rootf} (root folders) in drive c:\ except those prefixed with "S" (for skip).
skipped folders examples: c:\Sdocs, c:\Spics

#3
Perform subfolder rename as defined in #1 only on {rootf} (root folders) in drive c:\ prefixed with "P" (for process).
processed folders: ie. c:\Pdocs, c:\Ppics

Thank you!

JavaScript renaming, I'd think, could do that?
(How, is beyond me.)

#1: With the paid version, can type C:\ in the folder-path, with Filters(12) having checkmarks for "Folders" and "Subfolders".
Then javascript could rename any of your folders that are 4-or-more deeper than C: with something like...
if (/^([^\\]+\\){4,}$/.test(object('folder'))) {newName=name.substring(0,4)}

#2: To conduct everything in #1, but only when {rootf} starts with "P" ...
Can either edit this code, or just add a Filters(12) "Condition" like... /C:\\P/.test(object('folder'))
Then clicking the blue-arrows inside of Filters(12) will only present these folder-names inside of the file-listing.

#3: To conduct everything in #1, except when {rootf} starts with "S" ...
Can again edit the code, or just add a Filters(12) "Condition" like... /C:\\[^S]/.test(object('folder'))

For myself, I do usually like to edit the main code, instead of adding Filter(12) Conditions for the file-listing.
But its because Im usually wanting to also present everything that's not getting renamed by the main code.

Hi, Javascript renaming will do that as it can check the number of folders in a path and rename the folder.
But you need a commercial license for BRU to unlock javascript.
