When I delete a file and/or folder it doesn't show in the Recycle Bin despite of the setting Delete to Recycle Bin being checked
Why is that?
I can't say with limited information on what is happening.
What does the fileoperation log say ?
When you delete with that option MC is not doing the delete.. It is then all handled by Windows.
And Windows will move file to Recycle bin if possible
However some filesystem do not support Recycle bin.. Some networked share do not support it, configuration for recyle bin can be that it does not fit there so windows do not move it there.
