Delete System32 Folder?
My computer’s storage is getting nearly full, and I thought I would clear some space by removing stuff I don’t need. I ran across a very large folder named System32—it’s just chock full of stuff that I didn’t put there. Can I remove it to regain the space it’s consuming?
Should you delete the System32 folder in Windows? Here are two simple answers: a) You shouldn’t, and b) You can’t. The System32 folder contains a ton of internal files and programs that Windows needs in order to operate. If you try to delete it, or its contents, you'll get warnings and errors indicating that you can't delete the files. If you are persistent and override the security settings of the files so you can delete them, you'll watch Windows slowly die as files get deleted. (Think of the scene in the movie 2001 where the computer, HAL, has his memory wiped as he sings "Daisy, Daisy." It's the same thing, really.)
If you really need to clean up some hard drive space, look for videos or large downloads—those are the files that take up a lot of space. Large backups can consume a lot of hard drive space, as well. Remember that storage space is different from the amount of memory in your computer, and the amount of consumed memory. Running a lot of programs concurrently consumes your RAM (Random Access Memory) but this has nothing to do with your amount of disk-based storage.
We've mentioned it before but look for the application named WinDirStat on the Web. It's free, and immensely useful for determining what's taking up your hard drive space. You can find it online at WinDirStat.net, and you should check it out if you need to clean up your disk storage.
In any case, don't even think about deleting the System32 folder. Yes, it’s a large folder, but deleting it won't help, and it won't work.
