And if you use the 'Delete All' option, you will remove those auto-saved files from the list and will not be able to open them via the auto-save again.
So effectively you will lose all the changes you have made since you last manually saved the file.
This can be a good thing in this case if the last thing you modelled is causing Archicad to crash every time.
Your last manual save may not have this corrupt data.
But if it is a long time since you last manually saved you may lose a lot of work.
You can always open your last manual save (or even the BPN file which was the save before the last) and if you are happy to work with it then just carry on and delete the auto-save next time it pops up.
Otherwise it is sending in the bug report and contacting you local support (and not deleting the auto-save just yet) and hopefully getting a timely response and solution.
