When I click on the download arrow on another Plex Server, the downloads go to a fixed location (which isn’t obvious, and required a google search). I would like to download it directly to my NAS, is there a way to change the download location?
If you are using a browser on your PC when downloading, then you can change the save location in the browser settings.
Personally, I would write a small batch file that moves the file/s from your PC download location to the NAS.
Something like:
FOR /r %%I in (*.mp4, *mkv, *.mov) DO (
Move /Y "%%I" "\\DiskStation\Downloads\"
)
Place the above into your downloads location and name it transfer.bat or similar, then double click the .bat file to run it.
The .bat file will ask if you need to overwrite existing files on the NAS or not and it will only move files with the extensions you specify, .mp4, .mkv, .mov.
Note: It should work provided you are using Windows and you can see your DiskStation in Windows File Explorer under Network.
If you use Mac or Linux, then you may need to modify things a bit, but the same principles should apply.
Short answer:
No, you cannot modify the directory used for downloading. Downloads aren’t designed as a means to copy shared media into your own library.
