Running multiple instances of mpv shim in windows

[pictureeating]

If you have trouble in creating it you just have to create a txt file with the contents you want and then rename the .txt file to .bat

You can also open the text file and save as .bat instead of .txt

The content should be the following:

start "" "C:\Path\To\MpvShim\run.exe" --config "C:\Path\To\New\Appdata"

with the quotes as you see them.

The first directory points to the mpv shim executable which is named run.exe and you can find it in the installation directory.


The second one is just a directory of your choice in which the configurations will be saved.  It has been a while since I played around but any directory under your user will probably work (not sure if it will have permission errors otherwise).

Do not forget the quotes around directories and the two after start.

If you have any other questions feel free to ask!

I actually tried something similar a while ago but ran into permission issues when setting custom appdata paths — Sandboxie seems like a cleaner workaround. The .bat file syntax you posted makes sense now; the quotes really are crucial to avoid path errors. I might experiment with relative paths next to simplify portability between systems. Great job documenting everything so clearly, especially for your first guide — it’s the kind of post that saves people hours of trial and error.
