1. How it works now: When queuing files, winscp first reads all the files and calculates the full size, then starts the transfer.
2. Problem: When transferring tens of thousands of small files (like pictures), it takes more time to calculate the queue size than transferring it.
3. Solution: Option to disable FULL size calculation before transfer. (Maybe just do it for the current directory being transferred)
4. Extra: Since there is a size calculation, please show that size number for the full queue, and also number of files / estimated time remaining. (and maybe a graphic bar below the % number field)
