So this issue is occurring time and again after connecting my external HDD to my laptop. I'm literally seeing multiple entries for the same file when i switch to a folder. This happens for video files in external HDD and have attached a screenshot here.
This happens sometimes while USB-Drives use. The only solution is the Refresh-Command (View> Refresh).
Thanks. Hope something can be done to rectify this in the future.
This can happens sometimes. in very rare situations if the filesystem is triggered to be rescanned when it just have finished a scan and is updating the internal cache.
So it gets updated twice instead of once.
Doing a refresh by pressing F2/F5 should fix it.
Since it is very very hard for me to reproduce it,it is not easy to just fix. But the issue is under investigation.
