If you have installed OneDrive using the default settings then it is most likely that the OneDrive folder (sync folder) has been placed in C:\Users\Username. Can the location of this folder be changed afterwards? That's what we are going to see in this tip.
Well, the only way to relocate the OneDrive folder (without losing the stored content) is to first unlink OneDrive from your computer. Open OneDrive's settings, by right-clicking on its corresponding icon (notification area) > Settings. Go to General settings and click on Unlink OneDrive:
The Welcome to OneDrive screen opens, but you should leave it for now. Click on Start > File Manager and select the OneDrive folder. Go to the Home tab > Organize and then click on Move to. Select a new location for the OneDrive folder.
Go back to the Welcome to OneDrive screen and click on Next. Sign-in with your Microsoft account. Click on the Change button displayed next to Your OneDrive folder is here... and browse to the desired location, more precisely to where you have relocated your previous OneDrive folder. A small warning will be displayed "Files already exist in this One Drive folder". Click on Use this location to merge the folders:
In the next window, simply choose the items you want to sync and click on Next to finalize the installation of OneDrive on your computer.
