Change the OneDrive Folder Location

Technical Level : Basic

Summary

Learn how to change the OneDrive folder location. This is useful if you have a limited storage capacity main drive but a separate storage drive and you want your OneDrive content synced to the separate drive. This is not for OneDrive for Business.

Details

Many people use two separate drives on their computers: a main drive like an SSD to run the operating system and other programs, and a regular hard drive to store the bulk of their content. OneDrive defaults to the C:\User\\OneDrive location, however you can change it wherever you want.
