Rename the extension only (not in filename)

AndrewRH · 2021-09-01 14:42

Is there a way to select just the file extension for a renaming rule?
My goal is to recursively rename all movie files extensions (I need to remove a trailing underscore) - without affecting the filename (most filenames contain one or more underscores).
Some rules have a tick box to skip the file extension but not one to select just the file extension.
Thank you in advance!

(I also sent an email to den4b support for this; and if that person here, then please accept apologies for double-ask!)

FROM:
File_name1_test.ext
File_name2_test_.ext_
File_name3_test.ext_
File_name4_test.ext__
File_name5_test.ext___

TO:
File_name1_test.ext
File_name2_test_.ext
File_name3_test.ext
File_name4_test.ext
File_name5_test.ext

TRY:
https://www.den4b.com/wiki/ReNamer:Rules:RegEx
Expression: _+$
Replace:
[_]Skip extension

Explanation:
_+$
_ >> literal sign underscore
+ >> one-or-many of the expression right before (here the underscore)
$ >> match at the very end of the string
[_]Skip extension >> do not skip ext to work on the trailing underscores after the ext too

HTH?

I'll try that! Thank you!

There is another way:

- add all files

- mark only those with extension "*.ext" plus with something trailing "*.ext*":
Mark by Mask: *.ext*

- replace the extension on those files entirely by adding the three letter extension EXT newly:
New extension: ext

Additionally we could also create a PascalScript for that issue
There are often more than one way to perform it with ReNamer.
