Based off of the answer from Laurent above.

So the solution for this when using windows:

Use command prompt (open as admin)
Type in:

mklink \j "C:\SymbolicDirectory" "C:\Users\...\OneDrive"

Match the symbolic directory on both computers and point the second directory to the OneDrive folder on the machine.

It only works if you copy (ALT+paste or ALT+drag) the file from the Symbolic directory.

Adding new files to the Symbolic directory will place them into the original directory, so you don't need to worry about data not ending in the correct place.
