I don't have a recipe for this or even a rule of thumb. I usually know what the files are for (or can Google it) and decide on each case individually. For perl-cleaner output, the perl version of the old install is in the pathname, so I check if the corresponding file for the new perl version is already installed, that tells me the old one is safe to delete. On a 64bit system, I know the 32bit files come from emul-linux, so I can delete those too on the same basis. For everything else from perl-cleaner, I have to figure out why I changed the file myself and make sure the same change is present in the new version. It gets more complicated if you use cpan (stuff can get changed behind the scenes). So the best approach is always to understand what the various tools do and deal with it on that basis. Alan
