I've noticed that *.dnd files in ~/.kde/share/apps/ktorrent consumed 8 Gb of disk space.
As I understand, dnd means "do not download" -> just temp files? Wouldn't Ktorrent recreate/redownload it after deletion?
Is it safe to delete these files? Won't it affect my active torrents?
I've finally deleted it -> my 800 active torrents gone ^_^
Answer: don't delete *.dnd files if you don't want all your torrents to be deleted
From my simple understanding :
Torrent clients download pieces of data , maybe this piece for a file or another file or maybe it's the end of a file and the start of another one , or it's required to check the healthy of files
I used to use utorrent in the past/$windows$ and they end with .bat so i delete them after download and seeding a little . Although , I don't use ktorrent but I suppose the all follow the same principle
