I might even install two different versions of the sound mod, say 0.90 and 0.93 and swicth back and forth between them by changing the folders' names (really? would that work?)

I do this and name my sound mods as follows;

A1_BaseSoundMod93
-A1_BaseSoundMod92

A1 at the start of the name just makes sure it's the 1st folder read. The - (dash) character before the 92 version, prevents the folder from being read.

My Mods folder for illustration, as can be seen many mods have more than one version with a - (dash) before their name
