How to recover or create deleted 'Documents' folder in Home folder?

To create a new Documents folder

Open home folder > right click > new folder. Name it Documents

If the icon is incorrect then right click on the new Documents folder > properties. Click on the folder icon, this will bring up a select custom icon window.

Browse to File System > usr > share > icons > Humanity > places > 48 & select the 1st folder_documents.svg. This should restore the icon to your Downloads folder

Then gedit ~/.config/user-dirs.dirs or browse to file. You'll see this line - XDG_DOCUMENTS_DIR="$HOME/"

edit it to this & save. Then log out/in

XDG_DOCUMENTS_DIR="$HOME/Documents"
