Information, tips and myths - No.28 - Your documents are not in your documents folder!
If you use OneDrive, then your documents are not in your documents folder, they are in OneDrive's documents folder. You can go directly to your real documents folder at C:\Users\enter your user name here\documents. If your OneDrive is full or getting full, then you can use this folder. The same may apply to your photos/videos/music folders.
