 Can OneDrive backup any folder?

By default, OneDrive mirror folder requires a Microsoft account and its folder protection feature only backup or sync the important folders on your Windows 10 or 11 computer, including “Desktop”, “Documents” and “Pictures”.  If you are using currently Windows 7/8/8.1, you need to download the OneDrive desktop app first and then set it manually.

However, you can still backup or sync folders not yet in the OneDrive desktop folder. Just copy or paste it to that folder or use mklink to make a junction with the OneDrive folder, similar to the method in my earlier article: Move Program Files to another drive in Windows 10. In addition, you still can use the free file sync software AOMEI Backupper. Then, keep reading below and learn how to sync PC folders.

Method 1: Backup any folder to OneDrive with desktop folder

OneDrive comes along with your Windows 10, here I’ll take Windows 10 as an example and show you the steps to backup any folder to OneDrive. Also, you can use these steps in Windows 11. If you are using Windows 7/8/8.1, please download OneDrive desktop app first.

Step 1. Type “onedrive” in the search box and click the top result and sign in with your Microsoft account.

Step 2. Click “Next” to accept the default folder location for your OneDrive files. If you want to change the folder location, click “Change location” and select your preference.


Step 3. Click “Open my OneDrive folder” to access the desktop folder, then copy and paste files or folders need to be synced in that folder, Downloads folder, for example. At last, your files or folders will be uploaded to automatically.

Potential sync issues using OneDrive:
Tedious and time-consuming work: Syncing files outside OneDrive folder requires human intervention, so you need to keep copying and pasting over and over againe. This is very obvious especially when you want to sync a large amount of files or folders. 
Sync storage limit: The desktop app only allows you  to sync files up to 100GB.
Not effectively syn changes: Some users report that the desktop app will only upload the changed files or folders in OneDrive folder. That is, if you change files in the original location, OneDrive will not sync them.
Error prone: If a folder contains the important folder including Documents, Desktop, Pictures, Screenshots, Camera Roll, and OneDrive folder, you may receive error message, saying “Important folders aren't in the default locations”. Please move it back to the original locations.

Method 2: Sync PC folder to OneDrive with mklink

To sync PC folder to OneDrive with mklink, whether files, pictures, or videos, you need to get the location of the OneDrive desktop folder and remember it. By default, OneDrive desktop folder is located at C:\Users\Username. Then, see how it works with the following steps.

Step 1. Type "cmd" in the search box, right-click it and select "Run as administrator".

Step 2.  Type command line based on the syntax below. 

mklink /j "C:\Users\Username\OneDrive\folder name" "Full path of source folder" 

To sync videos to OneDrive: Taking "E: \videos" as the source folder full path and "videos" as the folder name, you are supposed to type as mklink /j "C:\Users\Username\OneDrive\videos" "E: \videos" and hit Enter.

Mklink Sync With Onedrive

• The folder name refers to a folder you want to sync with OneDrive, but not already in OneDrive desktop folder. This folder is a junction point of the source folder, so you'd better use the same name of both folder, which help know what it's linked to.
• The full path of the source folder is the path of the folder that needs syncing with OneDrive. 
• To undo the junction, just delete the folder in the OneDrive desktop folder and it does not have any effect on the source folder.

Step 3. Now, it will automatically create a folder named videos in the OneDrive folder and sync your videos in the F drive to that folder. All changes made in either folder will be reflected in another.

Method 3: Automatically mirror folder to OneDrive with AOMEI Backupper

Besides the above methods, you still can use a trusting and reliable file sync software automatically mirror folder to OneDrive. AOMEI Backupper Standard is a great choice, which can act as the middle man between local files and OneDrive.
