I just did a clean install of SW 2012 on my Windows 7 system and I've got SW files in the following folders...

C: Program Files

C: Program Files (x86)

C: Program Data

C: Solidwoks Data

Why does SW install spread everything out in so many different folders? 

Couldn't the TWO files in the Solidworks Data folder be in the Program Data folder?

What is the difference between the Program Files folders and the Program Data folders?  Can they be combined?

It seems there are similar types of files (and/or data) in these folders.  For example, the design library is in the Program Data folder.  Shouldn't this be in the Program Files folder with the other custom files like blocks and weldment profiles?

I just want to backup the folders in which I may have added custom parts, custom profiles, custom blocks, custom templates, etc.  These seem to be spread out all over the place and to get everything, I'm going to end up, backing up files that I don't need backed up.  I want a clean and simple backup.  I just lost a bunch of design library files because they were off in a completely seperate folder that was hidden. 

Which folders do YOU back up?

And, a little off topic... What does the SWBrowser.MDB file do?  The SWBrowser file is in a folder, deep within the C:Solidworks Data folder.  It's one of two files in that string of folders.

Thanks
