Sir, I have almost all paid File Managers. I only work on Commanders never on 'My Computer'.
There is a feature only in Multi Commander which is not in any other. I came across it only today.
I was copying (extracting) a file sized 7 Gb from an Iso file. While files was extracted I found two task bar MC icons, one for 'Multi Commander' another for 'Copy'. It took about 15 minutes on this operation. Being curious why two icons were showing, I started navigating in main window, and IT WORKED. I could change drive, change directory while copy continued. I did not have to wait for 15 minutes for Copy operation to finish.
On top of all, that 'Copy' window is so descriptive like showing bytes, time and many other, while copying.
This feature was available in 90's in Gyula's Navigator. Now on all File managers, main window stays locked until Copy is completed.. I have been suggesting them to fix this but I think they have no clue how to do this.
This was a pleasant surprise.
This is why I say Multi Commander is miles ahead of others.
Sir, please add this into your opening HELP dialogue. I am sure many who work with large files, would love this feature.
