"All Magic Folder does is move the files you drop on to it to a
folder that depends on the type of file configured through a
filter. For example, you might want all JPEG images to be moved to
your Pictures directory, or your Ogg Vorbis files to a Music
folder.
"Just set up a filter by clicking on the tool icon from the
Plasmoid. The configuration window accepts wildcards (such as *.jpg
for images), and if you uncheck the wildcard option you can also
use regular expressions. The expression .(jpe?g|png)$ would filter
both JPEG and PNG images, for example.
"Another feature of KDE's Plasmoids that isn't immediately
obvious is that you can configure your desktop according to
activity and switch between activities in the same way you switch
between virtual desktops."
