Mark even or odd file lines

Hi, is there any quick way to mark all even or odd file lines without doing manually?

I don't believe that is possible. However it is a simple matter to add only even or odd files to the list.

Use Add Directories and select the folder containing the files, then use a "Regular expression match".

For even files: use "[02468].srt"
and for odd files: "[13579].srt"

Otherwise you can use a regular expression to rename only files in the list ending in an even or odd digit - you may need to use a script.
