Say I have a 670 MB file and I want to copy it over the network using SMB (FROM a Windows machine, TO a Linux machine), and both Windows Explorer and Teracopy only get through like 10-50 MB and then freeze up and stop copying. And furthermore say that I can copy gobs of other files to the same server at the same time (like while the 670 MB file is sitting there stalled) quickly and without problems.

Any ideas wtf could be happening here? 

 Not saying there's not a better solution but I move large ISOs from windoze from a Debian shell on Windows Linux Subsystem (WSL) to Linux box using wormhole. The only requirement is being able to install WSL on the windoze machine. WSL actually makes the windoze machine usable. 😸
