Wildcard %year% or %month% is not expanded/ignored

Hi,
I use a small batch for automatic backups. The source (to be backuped) is stored for each month in an separate destination folder. The name is (for example : September) : Month_09
With this line (from my batch) I try to build the name of the current month, but it doesnlt work.
The wildcard %month% is totally ignored, Monat_ is used as destination.
The same is with %year%
What is wrong?
Best regards Klaus

There's nothing like %month% nor %year% in WinSCP. How did you come to this syntax?
For the correct syntax, see the %TIMESTAMP%:

What is wrong?? TIMESTAMP.... doesn't work correctly.
I use the following line (in a Batchfile) :
The Folder Monat_11 exists in the Server, but I get get the error :

'Fehler beim Anzeigen des Verzeichnisses "/Monatssicherungen/Monat_".
Datei oder Verzeichnis nicht gefunden. Fehlercode 2

In a batch file, you need %%TIMESTAMP#mm%%.
See the last paragraph of the section linked in my previous post:
