What I am speaking about is whether you had some hard time getting rid of some Old files that you had on your main Windows rig.
In my case, I have faced 2 major problems:
#1: Font files (especially the 8514x fonts from the 93~ era) cause Windows to hang explorer while trying to render them.
Solution? Restart your machine, dig deep back into the directory tree and remove them (if the files are in c:\myfiles\oldstuff\s3drivers delete the myfiles folder (but take your data out first ). I think there's a better way to do this, but this is just the fastest way to do this.
This problem has been solved with Windows 10 (to an extent)
#2: The CHICAGO SDK: Filled with many files that end with a dot (ex: /SAMPLES/.../Makefile.), and Windows does not except files that end with a dot anymore, so the files appear to be nonexistent on the HDD, while they are.
Solution? Open up a command prompt, navigate to each stubborn folder, and delete each file (del *.*). I think you can do this with rd or something like that, I didn't really try.
Did any of you face such problems? Post them here.
