cannot edit path for mydocuments

In the options under path, each function shows a path that is used except for My Documents - it is blank. after selecting EDIT and stepping through each part to select the final destination, and then OK, no path is entered and the place holder remains Blank. Have been working on Windows 10 permissions and nothing is corrected. Windows 10 1809, HP laptop, LO 6073, 64bit

Which OS? Eventually, which desktop? LO version?

Windows 10 1809, and LO 6073 64bit

A point of clarification – Are you trying to change the location or name of the Windows “MyDocuments” folder (probably impossible to do), or are you trying to store your documents in a different folder that has a different name (like “Docs2018”)?
