How To Reinitialize The Offline Cache in Windows 7, 8, 8.1, 10

Share This:


Sometimes you just have too many conflicts when synchronizing your offline files in Windows that you have to start over. In my case, I upgraded the file server to a new host and some clients were left with duplicate entries in their Sync Center.

DISCLAIMER: Always create a restore point before editing the registry! If you render your computer inoperable because of modifying your registry then you will have a better chance of recovery.

If you’re not comfortable using the registry editor, you can try using Microsoft’s Fix It tool from KB942974.

Registry Edit

  • Make sure that your files and folder have been synchronized. Reinitializing the cache prior to synchronizing will cause you to lose any data that isn’t synchronized.
  • Click Start, type regedit in the Start Search box, and then press ENTER.
  • If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
  • Locate the following registry subkey, and then right-click it:
  • Point to New, and then click Key.
    NOTE: If you already have a Parameters key here, then skip this step
  • Type Parameters in the box.
  • Right-click Parameters, point to New, and then click DWORD (32-bit)Value.
    NOTE: Be sure to select the 32-bit DWORD. If you create a 64-bit value, your computer WILL blue screen!
  • Type FormatDatabase, and then press ENTER.
  • Right-click FormatDatabase, and then click Modify.
  • In the Value data box, type 1, and then click OK.
  • Exit Registry Editor, and then restart the computer.

.reg File

You can also copy and paste the contents below into Notepad and save it as a .reg file. Then double-click the file to import it into your registry:

Windows Registry Editor Version 5.00
