Sometimes, while taking a backup of data from a PC to OneDrive, using the KFM (Known Folder Move) feature causes some problems and stops working. If you face a data synchronization issue, you are already in the right place.

Why is OneDrive KFM not working?

OneDrive Known Folder Mode not working is typically seen when Windows 10 build 17763 or later versions are installed on the machine.

More specifically, the Known Folder Mode will not work when Windows 10 build 1809 and later versions are installed on the server hosting the Client Access License (CAL).

The main causes that are disrupting the working of OneDrive KFM include.

  • Exceeded file limit – If you try to sync more than the allowed limit of 10,000 files with OneDrive KFM, the process will fail, and an error message will be displayed.
  • Incorrect file types – Only specific types of files are supported by OneDrive KFM. These include .doc, .docx, .ppt, .pptx, .xls, and so on. OneDrive KFM will not back up any other type of file.
  • Not enough space – If your system doesn’t have enough free space, then OneDrive KFM will not be able to sync your files.

How do I fix OneDrive KFM not working?

Before moving to detailed solutions, make sure to apply these quick checks:

  • Restart the OneDrive desktop sync app because sometimes it just needs a fresh start to work, and your problem could be resolved with a simple restart
  • Disable any third-party security software because some of them can interfere with the OneDrive app
  • Make sure not to upload unsupported file types. Files or folder name that contains the given characters ~ ” # % & * : < > ? / \ { | }. as well as trailing and leading spaces in file or folder names.
  • Make sure that you’re not syncing too many files. You must upload the files under the maximum limit. When the number of files increases, the performance of the local system decreases.

Now let’s jump to the solutions on how to fix OneDrive KFM in no time.
