I've been coming across, more and more lately, filenames that are preceded by :www.blabla.com - Filename. What I'd like to know is: Is there a way to filter off this addition to the filename and rename the file to the actual file. Filter the part www.blabla.com - off of the filename. I have a feeling that regex might be able to do this but I'm not a programmer. I'm a flat head(hardware) type. forgive me.

Thanks you!

Uhm you can use the Setting -> Transfer -> Files "file complete shell command" search on support here...
what you would do if you notice this EVERYWHERE is the eliminate regex for your extra files.
OF NOTE: you cannot do this before downloading, because the filename IS PART of the info dictionary (geek speak for you lose the swarm you're on if you change the filename).
YOU CAN however right click, file, location, re-path it to a renamed file (which would need to be done for each file in each transfer affected). which is why it's better to do this at the end.
If you have any questions please reply below :)

I guess I'll have a go with a batch file with shell commands in it to glean off the trash. I'll reply back after I find motivation to write a script and test it.

It would be nice if there were a section in these here forums where peeps could put their working scripts for others to rip. (off topic)

look in the scripts and/or help channel in tixati, people in those channels may be able to help you.

Like previous post says there is a Tixati script channel. unfortunately with channels being sporadic lately (due to overall global network congestion OR the massive UDP packet loss) you should probably go to dsc:cqtrmrfvac3nta3ndtoo3n2trq6wxa6aef7bleragj4evcjvcscq?dn=Tixati%20User%20Group%20-%20Help%20and%20Support
