FileZilla open/edit file error: A file with that name is already being transferred.
This error occurs when you remove queued file from the queue using the “Remove Selected” before download completion.
I was editing my code directly on server in some php files using the view/edit operation. For one file before the file was fully downloaded I removed it from queue. Now when I access the view/edit function again a popup window appears telling that “A file with that name is already being transferred”.
