Sonarr version 2.0.0.4146:
Mono version 4.2.1.0 (2016/01/11):
Linux - Qnap NAS
Just to point out that thumbnail folders from a QNAP NAS are still showing in the manual import screen (where you assign season name, numbers etc)
Syntax of folder is exactly:
.@__thumb/
Would be really nice to have these hidden please
