DDsopt question involving Skyrim Revisited: Legendary Edition

[FamousDeadGuy]

Did a quick search, couldn't find a specific answer to my 2 questions..

1. Is the process of ddsopt supposed to take hours? The main textures .bsa from the data folder took almost three hours.

2. I named the target folders the prescribed name "Vanillia Textures optimized", but the files that end up in the folders after the optimization are named "bsa.bsa.bsa" or something like that. Should I rename these?

Also, a quick explanation of how using these in the mod manager works would help me overall with my general understanding. Am I correct in thinking that the data folder is virtualized by mod organizerr and the .bsa's that you optimize and put in as mods overwrite the vanilla ones? If that is case, couldn't I just replace the vanilla files with the optimized ones in my actual data folder? Or would that be counter-productive? Thanks, ladies and gents!

I'm able to run both the 32 bit and 64 bit versions on my system. I do have both the 32 bit and 64 bit versions of the 2012 Visual C++ redistributable installed.
