Reverse Auto numbering to filenames?

[Jakov]

Hi All

Please, I sometimes download entire Youtube channel videos and my downloader add prefix number to downloaded files as follows:

So the first video in the channel takes the last serial number because the downloader starts numbering from the last to the first video (recent to old).
Is there any way to reverse numbering of download files, so the video lesson 1 takes number 1 not 010 and so.
I tried to remove the first 3 letters and add an auto number, but not benefit, because some files will take numbers different from the lesson number.
This course is just example because number of files vary according to the course, and some courses have no lesson number in their filename.

Thanks

Hi, try removing the fist 5 chars (everything up to SPSS), then sort in BRU and add numbering.
Or first reverse sort, then remove the first 5 chars and add numbering.

Ok, it's a good idea (reverse sorting)
Thanks so much
