In Options->Settings->Setup->Main Download folder: I changed $(SUBJECT) to $(RAWSUBJECT).
Setting is now: "J:\!G\$(GROUP)\$(RAWSUBJECT)\"
But instead of using the raw subject , all downloads go to a folder named "$(RAWSUBJECT)".
In the group properties (where I enabled "Automatic Download. Add all new posts to the download list."), I've done the same.
I changed the property "UnRAR folder:" to "G:\!D\$(RAWSUBJECT)\"
The result is the same, all files were unpacked to a folder named "$(RAWSUBJECT)".
By the way, the help text for "$(RAWSUBJECT)" is wrong. It says "The current date". (Column "What the Path Symbols mean".)
