To sync your OneDrive on your computer, you need to select a location that is formatted as New Technology File System (NTFS). See the OneDrive system requirements.
Check the file system of a drive
-
Open File Explorer.
-
Right-click the drive and choose Properties.
-
On the General tab, next to File system, see if it says NTFS.
Convert a FAT or FAT32 drive to NTFS
Converting a drive using these steps will preserve the files on the drive. We still recommend making sure you have backups of all files on the drive.
-
Find the letter of drive you want to convert. Open File Explorer, and in the left pane, look for the drive under "This PC" or "Computer."
-
Press the Windows logo key + R to open the Run dialog box.
-
Enter cmd to open the command prompt window.
-
At the command line prompt, type convert drive: /fs:ntfs
For example, if the letter of the drive you want to convert is e, you would type convert e: /fs:ntfs
Note: If you want to convert an NTFS drive back to FAT32, you need to save copies of any files you want to keep, and then reformat or partition the drive.
