Windows 7: Mysterious Boot Folder, very large, can't delete

Mysterious Boot Folder, very large, can't delete

I recently discovered a folder on my C: drive simply titled Boot. (Filepath is C/Windows/Boot) It is taking up 27 GB of my 37 GB available space. It wasn't always that large, but must have increased steadily in size in the almost 2 years I've owned the computer. This Boot folder has 4sub-folders, ranging in size from 4 GB to 10 GB, totaling the 27 GB, but when I open any of those 4 sub-folders, there are only a few files of a few KB each. This is not a hidden folder, and I located what I believe is theactual boot folder needed to boot up my computer. I am not able to delete the C/Windows/Boot folder or any of the folders or files inside of it. (It says I need administrative privileges, but I’m the administrator and the only user of the computer.) Starting a few weeks ago, this folder is causing me to continually get “Low Disk Space” pop-up bubbles. The other night, I cleaned up some spaceon my computer, ended up with 750 MB of free space, went to bed, and woke up to find I was down to 42 MB of free space. I suspect that somehow, stuff is automatically getting dumped into C/Windows/Boot. Would love to be able to fix this so I’m not always dealing with the “Low Disk Space” message. Any help you could provide would be greatly appreciated. (Laymans terms please, if possible.) Thanks in advance.

First take ownership of that folder. Then try to delete it.

Add "Take Ownership" to Explorer Right-Click Menu in Windows

There may be hidden files. If you press Alt --> tools --> folder options --> view, uncheck "Hide protected operating system files (Recommended)"

That might give you a chance to see if there are any hidden OS files taking up massive amounts of space. I also have a boot file in my C:/windows/ directory, but it's only 27 MB

Are you sure?

My C/Windows/Boot file in Windows 7 is only 27 Mb (instead of your 27 Gb)
Mostly containing languagepacks.

On D is the Bootfile 14 Mb (of 100 available) Also mainly languagefiles.

Whith "moveonboot" you could delete nasty files.

Don't delete your bootmanager or the system won't start anymore.
