To access your primary folders (libraries) and documents across all your devices, store them on OneDrive instead of the hard drive.

The folders in the Windows Library (Documents, Pictures, Music, and Videos) as well as other frequently used folders (Desktop and Downloads) are placed on the computers hard drive by default.

They are placed in the folder:

C:\Users\[Name]\

To find all these folders on all devices, simply put them on OneDrive.

First of all, open the File Explorer.

Then in the left panel, you will find the different folders. Rightclick on one of them.

From the context menu, click Properties.

In the Properties window, go to the Location tab. Click Move.

Select the corresponding folder in OneDrive. If it doesnt exist, create a New Folder for it.

The link has changed with the mention of OneDrive. You can notice that the path is always on the C.

OneDrive is constantly making a local copy of your files and syncing with the cloud. This way, you dont lose your changes if you have a connection cut.

Confirm the message that asks you if you are sure you want to move your file.

Repeat the operation on the other folders.

So you will find all your documents, images, music, videos, etc. on all your devices (including mobile).
