Hi Martin,
Correct, I have "calculate total size" turned off.

I did try the setting to on, and the percentage shows properly then, but I usually have it off and it still shows when transfering more than one file.

Thanks,
Stian

Thanks for your report.
I suppose you have Calculate total size transfer setting turned off, right?

Hi,
using the latest betas in the 5.2 series, specifically 5.2.3 I have noticed the progress % indicator does not work when transfer of a file is going on. The percent just stays at 0% during the transfer. Only one line of progress is shown.

However, the percentage works when more than one file is being transfered. So I am guessing this is the total transfer progress - but this is not very useful when copying just one large file.

I have tried with 5.1.6 and it works as expected there, showing two lines, one for total and for each file.

See attachment for screenshot.
