Hey guys,I accidently switched on sync for one of my hard discs. After disabling it I noticed that 200+ gigs are now being taken up by sync files. So with that said, does anyone know were these files are located so I can delete them?

You may try Previous Versions function. Please right-click on the drive, click the Previous Versions tab, and restore to a previous version. If the issue still occurs, please let us know more information. Please let us know where is the synced drive located, and how do you synced it by accident. Also please let us know how did you find that 200 GB space is taken over. You may capture screenshots and submit them in SkyDrive of your Live Space. Then give us the web address. We would directly access them then.Arthur Xie - MSFT

I had the same issue with some ghost files in my offline files. If you try deleting the offline cache and the files persist you can delete them from c:\windows\csc.

Thanks guys... I appreciate it all your help.BTW Arthur: The sync drive was NAS and I accidently pressed the offline key which then proceeded to back up my movies from the NAS drive. Upon completion my C: drive went from 800+- gigs of free space to about 600 free gigs.
