No it is nothing wrong with the disk
It is a know issue, That can happen very rarely on some system.
The duplicates are only in a cache inside MC. not on items on the disk.
If you do a Forced Refresh it will empty cache and scan again and it will fix it self.
(press F2 , or Shift+F2 to really force it (Or F5/Shift+F5 if using Explorer Styled setup instead of Commander Style)
It can happen on slow or very busy HW (or maybe combination of both) when there is a lot of file changes happening. When file changes are happening it will trigger a refresh. And if there area a lot of changes happening a second refresh can be triggered before the previous one is completed in a way that make both refresh operations update the same cache. That should not be possible but someway it happens.
I have not been able to recreate the issue my self so I have not been able to really track done exactly how this can happen.
However a Force Refresh will fix it.
The issue might possible be avoided by changing a tweak setting.
Menu > Configuration > Core Settings > File System (tab)
Scroll down to the last "Tweaking" section and there is a setting called "Browse Filesystem timeout (ms)" by default this is 1500 (ms) change this to 0.
This should disable multiple scan request at the same time. (Maybe)
=================================
If you are able to recreate this and are willing to create a debug log for me.
Type "dbg fslog" in the command line field. You see a Messagebox saying "Restart MultiCommander"
(Type it again to turn it off)
When it happens again.. Open a new MC and go to the log log folder. ( type ":golog" in the command line field to go there )
Find then latest "<date>-(num)-
FileSystem_debug.log"
(Or second latest. becuse the new instance of MC will also create one. and we want the one from the other instance)
Upload it to
http://multicommander.com/upload However the log contain filenames and paths. so I understand if you are not willing to send it.. thats okey..
