When installing what happens to AppImage apps already in use?

[atrugiel69]

Title says it all. I have apps already in use that are in the AppImage format.

One of those is qBittorrent. Losing data there would be catastrophic for me. I read about AIL moving stuff around and I would want a clear picture of what would happen for existing, in use, applications.

To clarify, I would obviously stop all AppImage programs before installing AIL. That's not what I'm worried about nor asking.

To further clarify, I am referring, in the qBittorrent example, to the data contained in directories such as:

/home/atrugiel/.cache/qBittorrent
/home/atrugiel/.local/share/qBittorrent
/home/atrugiel/.config/qBittorrent

The program itself sits in
/home/atrugiel/AppImage/qbittorrent-5.1.2_x86_64.AppImage

Thanks in advance.

EDIT
Second question, if I may. In the above example it's clear that many AppImage programs (all, probably), create directories where they save data/cache/whatever. I saw in a video that AIL offers the functionality to remove AppImage programs from the system. But does that remove the existing data directories that the programs created when used?
