I.e.

do not use D:\Calibre Portable\Calibre\calibre-debug -g

do use "D:\Calibre Portable\Calibre\calibre-debug" -g

See How to Escape Spaces in File Paths on the Windows Command Line for a bit of help.

thank you for suggestion.

@DNSB yes. to be on a safer side, I always enclose the file path with quotes. btw what does -g switch do in your script?

@capink I think I'll give it a go, but in the settings dialog, which one should the path of portable calibre be in? User variables or System variables?
