[Bugs] All Jolla apps not indexing sdcard in sailfish x

I have a 64GB SD formatted to FAT32, chock full of music and audio books. Media app shows them just fine, though it takes a couple seconds on startup until it lists all 7000 files.

the native apps show media files, but they don't put them in the folders they're already in.

3rd party & Android apps do index the media files, showing them in the folders.

A list isn't practical to search with a large number of files either ... nor is there a sort function, without using 3rd party apps

The native media app works with metadata (as collected by tracker), so even the track list shows tracks in proper order grouped by album. The idea is that you don't have to care where exactly the music files are stored, e.g. internal memory v.s SD card. And you can search the meta database with live updates to quickly find things. Of course, if you never tagged your music files at all (eg. id3, mp4 atoms, vorbis comments) the tracker and the media app have nothing to work with, and I can see why you won't be happy with their results. If you really prefer pure folders for organisation, there are other native player apps that work on that basis.

Okay, thanks for that informative information, honestly that whole metadata is new thing for me. :P

How about the camera app when storage is sdcard for pictures, I mean the pictures what I take will not show automatically, so I need use filemanager to make metadata for them everytime when picture taken? That's not handy...

Any advice?

Just checked, pictures taken to sdcard show up in gallery app, and tracker knows about it. You can check for yourself in developer mode terminal, using command tracker-info /where/ever/your/image.jpg will show resolution etc. So I assume your problem may be related to your sdcard format, try a cheap FAT32 card and see what happens. If you suspect tracker is at fault, there are some more tracker terminal commands to check its operation and diagnose problems.
