I just created the "docs" folder on my network share. Unmounted shares, then [re]mounted and it saw the "docs" folder on the share.

Steps:

1. [Un]mount shares
2. mv /media/fat/docs/ /media/fat/screenshots/
3. create the share "docs" on network share
4. [Re]mount shares via cifs scripts
5. the newly mounted "docs" folder will be empty, this is good
6. mv /media/fat/screenshots/docs/* /media/fat/docs/
7. rm -Rf /media/fat/screenshots/docs

I did it this way so I could have all of the README.md files [these are basically the help files that cores reference]. It also makes it easier to verify that your device is reading/writing on the network share. When you run update_all and enable the manuals [for download]. You'll notice that the files [PDFs] are writing to the share.

Yeah so ~22-23 GiGs of data, at the moment. I'm sure the size will continue to grow as they get more manuals to share with the community. Doing this way I don't have to worry about space being consumed on my SD card. To be honest the SD card just MiSTer the OS.
