Listrary 6 using >590mb ram

Is that normal? I mostly use listary for the popup menu and click switch, direct folders uses 5.9Mb ¯_(ツ)_/¯

Sorry, you can’t compare a simple tool like direct folders with Listary.
My system has the following Listary tasks

ok so why would mine be 590MB?

I guess you started some programs from a Listary search
This programs may count to the parent process which is Listary.

Mine is 180 Mo and more at the start up.
