Why is the Content Layout stored in the resume file?

[welp-ops]

The TorrentInfo::setContentLayout function, which actually applies the content layout (i.e, creates or deletes root folder), is only called when the torrent metadata is first loaded, i.e., when the torrent is first added. Changing the content layout later is not possible through the GUI and is not implemented internally either. So why does qBit go to the trouble of saving the content layout in the resume file, under key qBt-contentLayout?

The file structure of the torrent is "set in stone" (i.e. the "original" layout) in the .torrent file so qBt has to know about any deviations from it and re-apply them on every startup.

But libtorrent stores the file names in the resume file automatically -- there's no need for qBit to store additional information. For example, qBit's "rename file" feature does not affect the resume file; libtorrent handles it. It's clear the developers of the content layout feature understood this, because the TorrentInfo::setContentLayout function is only called when adding a new torrent -- not every time qBit starts up.

Well, you probably have to call the devs for such a technical question because i don't think they read Discussions.
