I can't understand how mimeinfo.cache works

Hello everyone,

I'm struggling with the /usr/share/applications/mimeinfo.cache file. I'm using labwc and PCManFM, and every update VS Code replaces "inode/directory=" with itself, preventing opening folders with the "pcmanfm-qt.desktop". To be honest, Kitty is doing the same thing, yet it put itself in the following position, so this doesn't prevent me from using PCManFM.
I believe it's a noobie question, yet I'd like to ask for help.

Thank you for any help.

Don't rely on  /usr/share/applications/mimeinfo.cache it is rewritten very often.

create a mimeapps.list file in ~/.config/mimeapps.list (per user) or /etc/xdg/mimeapps.list (systemwide) with your desired default applications, see https://wiki.archlinux.org/title/XDG_MI … eapps.list .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

This file "~/.config/mimeapps.list" already exists.
I added "inode/directory=pcmanfm-qt.desktop" to it.
Thank you!

Any idea why this was necessary initially? Why does /usr/share/applications/mimeinfo.cache exist if it appears to be an unordered version of /etc/xdg/mimeapps.list? And much more so, why would it thus be used for MIME type affiliation?

Re: I can't understand how mimeinfo.cache works

Because each application that supports a mimetype gets added there so you can have "Open with" integration and the like. Unless you made a preference clear via explicit configuration you need to have "some" place where that information is present so it can be used for that.
