It's one of the best FTP clients if not THE best for its many options and tools.
FYI: After I installed version 5.19.4, the generator of HTTP URL command stopped working.
The error was that the system could not find the file.Cannot execute 'powershell.exe -ExecutionPolicy -Bypass -STA -NoProfile -File "C:\Program Files (x86)\WinSCP\Extensions\GenerateHttpUrl.WinSCPextension.ps1" -webRoot
But in all previous versions worked perfectly.
I spent at least two hours trying different configurations and other ways.
In the end, I reinstalled an older version 5.17.4 (build 10410) and it works perfectly again.
Thank you again :-)
