I've updated the online copy of the script, so you can grab it there for testing:

I appreciate any feedback.

Hi Martin
I just sent you the eMail you asked for.
Have nice day :)

Thanks for your suggestion. I'll try to improve the script.

Can you send me an email, so I can send you back an improved version of the script for testing, once I have it? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

Hi there
I use the Keep Local Directory up to Date script to get data from remote sftp servers that are connected via a 4G SIM-cards. When starting the script, the user (I) only get two lines

Connecting...
Synchronizing changes...

And that's it.
It would be really nice to have some kind of progress bar or an output of some sort to reassure the user (me) that things are still going well.

Thank you for WinSCP!
Best regards, Axel
