Thank you Martin

That's indeed what I wanted ... and now I see that highlighting and selecting
Open from the Files menu also works. However, I've now changed the double-click
action from Edit to Open.

You've done a wonderful job with WinSCP ... it enables me to work on one machine
and delve into remote machines as if they were directly on my desktop, without
doing the boring ftp and then open.

All the best,
Greg G.

You probably want to change the double-click action:

When I installed WinScp under XP, I could just click on a file in the WinSCP window and if it was a .pdf file, it would open using Adobe ... .xls and .csv files would open using Excel. In the background it was creating a temporary directory on Windows, and then opening the files using the XP installed application.
This was very convenient.

Now, I've been 'upgraded' to Windows 7 ... and I've installed WinSCP again, but clicking on a file in the WinSCP window doesn't cause it to be opened using a Windows 7 installed application ... I need to move it over to Windows 7 first, then find it in the moved-over-to directory and then open it ... and that's nowhere near as convenient.

Can one get the XP behaviour in Windows 7, with WinSCP? Did I miss something in the installation? I've installed 2 different versions with the same result.

On Windows 7, I tried both the newest beta version, and
WinScp 4.3.5. On XP, I used the version that
was current 6 months ago. I can't quite recall what version that was.

Regards,
Greg G.
