I have a bit of a tricky situation here. I normally use AnkiDroid, but the only (Windows) computer I have access to for heavier editing of my decks has a locked desktop.
That means that I cannot export the changes I made as the desktop cannot be modified. Is there a way to export to another path?
Do you have an AnkiWeb account that you sync to regularily?
If the changes are only available on the computer, then I think you have no option but to transfer them somehow from there.
If you really don’t want to lose your collection on the computer, a possible but complicated solution would be to use a Live USB.
The other issue I didn’t mention is that the computer also has all internet access disabled. As it also would not allow me to install Anki without admin permissions, I am in fact already running Anki from a USB (‘Anki portable’). Or did you mean running Windows from a USB?
Could there be some way to convert the files from the ankidata folder into a .colpkg?
Is there a prompt in the newest version of Anki desktop? I didn’t try updating since even the manual’s phrasing seemed to imply that it always exports to desktop.
