How to add script to bat file?

Question

cmd/bat

Help solve the problem.
There is a batch file:

pushd "C:\Test" && (forfiles /d -1 /m *.css /c "cmd /c del /f /q @file")
popd

It removes all css extension files older than 1 day.
How to finish it so that it saves the last 2 copies of the file.
Simply put, so that there are always 2 latest versions of the file.

And in my case, it turns out that if no new files appear for several days, then everything is deleted.

Answer 1

It is clear that forfiles will not work for your purposes.
You can take advantage of the dir command's ability to sort files on output. You can see an example in the question that was here the other day:
You need to traverse by original files (not copies), then use the above dir to get the list "original file + its copies", sorted by date of modification in descending order, leave the first 3 files, delete the rest.
If you want details, then describe how and when you create copies of files and how names of copies are formed. Where are the copies and original files?
And in general I would like to understand what you are trying to do with this script. Apparently this is something like a system of cyclic backup of source texts with the preservation of the last few copies. Why not use git for this?
