Offline folders OFTEN get currupted or take up way to much disk space. Disk space is becoming less of a problem as most new computers come standard with 500gb of storage. However, offline files quickly overtakes a 20gb drive! Yes, we can adjust the amount of space offline files use, however this diskspace never seems to be taken back, even after files on the server have long been deleted!

I have found the only way to get rid of it is to delete the offline files cache. To do this you must open any folder, then from the menu choose Tools, Folder Options, click on the Offline Files tab, then hold both the ctrl and shift key while pressing the delete button!!! This will clear the cache and you MUST reboot right after you complete this or it won't cleanup properly. Yes, you can turn offline files off then back on but you don't get the same results.
Note: If you are a home user offline files can be turned off altogether. Offline files feature is only used when your computer is on a network and your files are stored on a file server. The offline files feature keeps a hidden emergency copy of all your files locally on your c drive. If for some reason your companies file server is down your computer will automatically pull from the offline files area. Once the file server comes back online your computer will automatically update the files to the area you normally store them on the server.
