The main part of it is a copying of the new animations. And I can't guarantee if there won't be any old bams with such names in \override\. It's necessary to guarantee that nothing old would be copied from \override\ to biffing folders later to replace mod's resources.
I think I understand what you mean, but it doesn't make much sense.
What you mean is that you have to ensure that no old files are located in the override directory to override the newer files in your biffs. Now, this makes perfect sense to me. However, you might have noticed that CBisson didn't leave his stuff in the override, either, so I believe that the risk of having old files there is minimal. If so, it's probably the player himself who have fiddled around, in which case I'm pretty sure he is able to work it out by himself that he shouldn't have old files there.
But, you say "copied from \override\ to biffing folders", which I don't understand. You do understand that you don't need to have the files in the override to be able to biff them, right?
What we're talking about here is to be able to dramatically reduce the size of both the tp2 and the bat, which would make installation much faster for the end-user.
Oggdec version 1.0.1 doesn't take regexp
D:\Games\Black Isle\BP-Test\SoS\SOS\OGG1>oggdec.exe *.ogg
OggDec 1.0.1
ERROR: Failed to open input file: Invalid argument
I just spent the better half of the last hour trying to find the answer to this one. You are prefectly right - OggDec 1.0.1 doesn't support regexp/wildcards, and since you claim that to be the latest version (which it apparently is), how come I'm able to use it without any difficulties at all?
It took me 55 minutes to figure it out, and 5 minutes to smack my head, since it's a truly simple solution and I still can't believe it took me this long.
See, we're not using the same software. As I was explaining to Shed, you assume I'm using WinAmp 3 while you're using WinAmp 5, while in fact I'm using WinAmp and you're using Windows Media Player. It's two programs with the same purpose and functionality, but still a bit different. I think what confused me at first was that the program is called the same thing - OggDec.
You're using OggDec 1.0.1 by Michael Smith, and I'm using OggDec v.1.9.1 (libVorbis) by John Edwards.
Granted, your software is a bit newer (if we look at release date), and about half in size. Mine, on the other hand, is more powerful and supports wildcards/regexp.
Now, you have a choice to either continue using your software or changing to mine; but I would advocate using mine, since you would be able to use wildcards in the .bat-file, which would both reduce its size and be a safeguard, in case you've accidentally forgotten to name a soundclip or two, or just made a typo (we all know how easy that can be). I don't think the size of the software matters much; 73 KB vs. 152 KB doesn't make much of a difference in a 176 MB download. And sure, yours is a bit newer, but seeing as none of them have been updated for the last two years, I don't think your OggDec includes any pioneering technique you just wouldn't do without.
I'd recommend do not uninstall anything at all in the middle of playing taking out anything from the middle of installed mods stack.
I'm afraid I don't entirely understand what you mean.
But even in this case there's NO chitin.key issue just because all mods that were installed after the one that is being taken out will be: 1)uninstalled first 2) installed after. And a copying of chitin.key after mod's uninstallation just returns everything to the state that was BEFORE that mod installation. But immediately after that all other mods will be reinstalled and, if it's necessary for them, will made all .key modifications once again.
The same is with \override\. Just think carefully.... step by step....
What you are forgetting is the fact that
the player might have made changes - such as manually biffing files in order to avoid the stutter bug (and thus updating the chitin.key) or adding his own items/creatures/whatever to the override-folder without using
WeiDU. There are a lot of players out there perfectly able to add their own Super Hackmaster +12 with IEEP, which would disappear if you manually replace the entire override folder when uninstalling
CtB.
You are still able to screw up the entire game because of the chitin.key and override overwriting, which I why I'm recommending using my (somewhat foolproof) method of removing biffs from chitin.key and removing the override replacement in its entity.
If you will still have some doubts I'll draw you a diagram.... 
I'm not very fond of being addressed in a condescending manner on my own forum, especially since I know what I'm talking about and only want to help.
