Comment (by i30817):

 There is a (slower) workaround for this on android (since android disables
 mount and fuses, the only other way is the app internally having a webdav
 client which not many do).

 Since the android port can use SAF paths, and since
 https://github.com/chenxiaolong/RSAF exists, you can install that and
 configure it (it uses rclone internally) to have some webdav remote that
 encompasses all the games you want to add.

 Then instead of scanning in the gui - far far too slow because it's
 recursive and full of 'unknown Ags or director games'), you can instead
 login\ssh into the machine that holds the server, install scummvm there
 and add the games there from the command line since it's much faster, and
 by a very lucky accident instead of adding 'unknown Ags game' it just adds
 what game it thinks it is based on the filename (even if the checksums
 don't match).

 Since I separate Ags and text games from other scummvm games I do this
 with (Linux):

 (you need to do this in the base of your scummvm remote if you want to
 minimize the search and replace later)

 rm -f add.log; find ScummVM ScummVM_Text/ ScummVM_AGS/ -mindepth 1
 -maxdepth 1 -type d -exec echo "{}" >> add.log \; -exec scummvm -a -p"{}"
 >> add.log \;

 you can search add.log then for games with weren't added (search for
 'Added 0'), there is always some, either because you don't have a recent
 enough scummvm or because the game files aren't in the top level dir
 you're searching.

 Anyway after that you have a scummvm.ini file with all games in
 ~/.config/scummvm/scummvm.ini

 copy that to your android device, and in there go to the android scummvm
 global options, then try to open a file and go up in the filechooser until
 you see the line "add a remote path" choose that, then if you have rsaf
 active (you probably want to give it permission to run in the background
 and without memory limits\without memory optimization in android, it's a
 option inside the rsaf app), there will be a option to connect to the rsaf
 remote either in front of you or if you click on the 3 lines in the top
 left.

 Do so and "authorize" that base dir.

 The scummvm file chooser dialog will appear with a strange path (for me
 it's /saf/games%3A because my remote is called games). Note it down. Then
 go into global options, backend and export configuration (this saves a zip
 file in your android device somewhere).

 Then open the scummvm.ini file you transfered to your android device and
 find replace all

 path=

 by

 path=/saf/games%3A

 save. this turns all your paths there to paths to your games in the remote
 (note that this is why a told you to call find in the top level webdav
 dir, if the paths there are absolute or something like that, you need to
 replace a larger party than just "path=" until the paths match the SAF
 webdav paths).

 Find the configuration zip file you saved and replace the scummvm.ini file
 you saved with the newly edited ini file. Then import that configuration.

 If everything went right, you'll have your whole collection of games
 pointing to the webdav remote. If something went wrong it's typically you
 trying this without adding the remote path to android scummvm with that
 add game just to authorize the remote webdav path thing, typically because
 you reinstalled scummvm or cleared its storage.

 Very annoying yeah? But much much MUCH faster than waiting for the gui to
 recourse into tens of thousands of directories through webdav, running in
 RSAF (even slower), which is the alternative.

 My speed for games in this is extremely bad for larger than 1 gb games or
 games with lots of small files, or worse, both. But I have a very bad
 server computer and only a 1mb speed intranet (if I'm lucky), your
 situation may vary.


 It's another thing altogether to get this working both inside the intranet
 and outside. I do have a hack that works for me, but it's so config
 dependent and fragile that I'm not going to say it here.
