How do I make “Documents” under This PC refer to a local folder?

Hey Durangoforcards, I noticed that you use under-dashes for "colons" and "slashes" in the naming of your files in File Explorer (because File Explorer cannot accept the colon ":" nor the slash "/").

I use colons and slashes in my file names by using the alternate Unicode version of those characters. You can try it out if you want (copy-paste the following Unicode characters to your file name in File Explorer. It actually works)

For the colon, you can use ։
For the slash, you can use ⧸

Durangoforcards,

I only mention it since you can see that "This PC" and "Quick access" in the screenshots below are different locations. What you see at these different locations may help determine what the issue you're having is. So far, it appears that you may have the normal separate OneDrive and user profile (tomst) folders for these.

In your "Quick access" screenshots in post #9, they all appear to be located in your "tomst" folder (listed as "This PC"), but this is normal.

Seeing a screenshot for where the folders are at from post #7 may help to sort this.

Durangoforcards,

Just to verify, double check to make sure that you have the items below set:

OneDrive auto save for Documents and Pictures is set to "This PC only".
Auto Save Documents and Pictures to OneDrive or This PC in Windows 10 Windows 10 General Tips Tutorials

Documents and Photos are set to "This PC" in storage settings.
Change Storage Save Locations in Windows 10 Windows 10 Customization Tutorials

Looks good so far.

Do remember doing or installing anything to add or change these two folders in "This PC". For example, some 3rd party tweaking programs have the option to add or change folders in "This PC".
