Doesn't work for me - do you have a pm address I can send a file to? The command I used was:

Picoscope /c C:\convert\*.psdata /f csv /b all

I get one converted file with zero bytes - I have three files all with tywo waveforms, as such, I expect six files to be output.

Thanks,
Carl.

I'd just like to add... I've also tried the latest beta and I am finding it fine to convert a *.psdata file to a *.csv file as long as I am not using the /b command. As soon as I use the /b (multiple waveform) command I get the same problem as mentioned - *_1.csv, *_2.csv etc all zero byte file size.
