As of now, the file deselection behavior is changed, it is now possible to deselect a file and keep the data around for seeding.

This is now the default behavior when you uncheck a file in the infowidget. In the context menu you can still choose to delete the file.

When you initially load a torrent and you deselect a file, it will be treated as if it is deleted, if however an existing file is found for the deselected file, it will not be deleted, the existing file will be scanned and any data found will be used for seeding.

Thank god, I was going to file a bug.

Spacebar = deselect = delete the file without asking = sadness.

Glad this is fixed.
