A full disk crashes after converting video to images

[Avasam]

After converting I got a warning message about possible dropped frames, then it silently crashed.

Here's the most relevant error from windows event viewer. (the rest are generic file write errors with no stacktrace)

Not sure how to handle this properly yet as I don't think I can reliably estimate how big a conversion will be be. But I'll look into it soon. At the very least I'd like to give a warning if it happens.

Me neither, but if you can just catch the raised System.Configuration.ConfigurationErrorsException exception. Showing a warning would be preferable over a silent crash (even if Unload still closes itself afterward).

I knew what the issue was here, but another user may not guess/realize their disk is full.
