Old versions stacking up

1.    SMF Gallery Pro    6.7    [ Uninstall ] [ List Files ] [ Delete ]
4.    SMF Gallery Pro    6.5    [ Upgrade ] [ List Files ] [ Delete ]
5.    SMF Gallery Pro    6.0.5a    [ Upgrade ] [ List Files ] [ Delete ]

Am I supposed to delete all these old versions after upgrading?

You do not know have to. It doesn't affect anything.

[lewism]

Ok but, out of curiosity, does it leave a lot of old files around that really should be deleted?

[SMFHacks]

No it only leaves one zip file.

[lewism]

Ok, so removing them won't mess up the actual install and leaving them leaves only a zip behind.

Got it, thanks.

You shouldn't remove the oldest package which you did the full install if you remove you can't unisntall then you would need to uninstall manually.
