hehe, no, my idea is not that time-consuming
are you playing at pokerstars? the hand histories for pot limit should then have "pot limit" in the file name while the limit ones only have "limit" in it.
if you have all your hand histories in one folder you can use the windows explorer search function to search for search string
pot limit in that folder and it displays only the files for pot limit. if you mark all files directly in the results window, create a new folder and drag them there, they are removed from the original folder and that original folder should now contain only limit hand histories.
does that make sense?
maybe someone has a better idea or tony can help
