I don't think the end operation matter as I doubt it has an option to do what I want : skip the 1st 2 files (should there be more than 2). I'd likely have to do some kind of loop ; 1st creating a counter incrementing it each iteration, in the iteration a verification would be made if the counter is greater than 2 (hopefully a constant can be used instead of 2), if passed the end command would be applied to the file name. That of course is just a way to do it, and there could be better ones depending on the availability of (complex) commands/scripts.
Here's an example:
dir /b OPT2 DIR1
fileA
fileB
fileG
fileH
fileT
and as the 1st 2 are fileA & fileB, the is a del for each of the following files ; so del fileG, del fileH & del fileT.
