This refers to the comments in the LostInLib post, as the explanation is too long to put a comment.
You need to understand the difference between libraries and the document folder, because they are not the same thing. C: \ Users \ USERNAME \ Documents - the default document folder C: \ Users \ USERNAME \ AppData \ Roaming \ Microsoft \ Windows \ Libraries \ Documents.library-ms - this is a library called Documents, the library is an index of all the locations you add to him, it does not need to be associated with C: \ Users \ USERNAME \ Documents, for example, on my network. I have set the value \ server \ users \ USERNAME, so when users go to the document library on the Start menu, they are redirected to the server share. You can also have more than one place in the library so that I can use my LOCAL documents and my document server, so when I went to my document library, they displayed both folders in one place, so they would look like in the same folder of mine documents.
So, assuming my documents will be here, not very good, since it should not be C: \ Users \ USERNAME \ Documents, just like libraries, it should not be here C: \ Users \ USERNAME \ AppData \ Roaming \ Microsoft \ Windows \ Libraries \ Documents.library ms if you redirect your appdata folder, for example, as on the network, your libraries can also be here: \ Server \ users \ USERNAME \ AppData \ Roaming \ Microsoft \ Windows \ Libraries \ Documents .library ms
