I'm a dedicated Linux user so I find mounting folders via sftp via the file manager easy. Or via "sneaker net".
I am a dedicated Google drive user who has also been known to use SAMBA to write direct to ~/linuxcnc/nc_files folder from Windows.
This lets me sit in an air conditioned office and use Sheetcam and Fusion360 to output files to the machines when its +40deg in my workshop
