So I finished a torrent download and then hit remove task, but on accident clicked remove task and all files, is there a way to get those completed files back or do I have to download the torrent again? Thanks.
you can try with data recovery program but the chances are not so good (40%). Do not save or make any changes on your hard drive for best chance for recovery success.
in the future always use the delete key of your keyboard to delete the tasks - it deletes the task only. later when you preview your files you can delete them manually.
