UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support When can I delete old 5.xx CGI files ?

I finally upgraded to 6.05, and now I have 125MB of CGI files from 5.xx laying around. I deleted the HTML files as instructed in the upgrade_from5.txt file.

I see many duplicate CGI topic files between the 5.xx and 6.05 folders, so this seems like a big waste of space.

When can they be deleted ?
