I tried this from the command line but it will obviously not work:

C:\>mminfo -q "client=name1,level=full,savetime>-7days,name='C:\'" -r 
"client,name,level,savetime" -ot
 client    name                             lvl  date
name1      C:\                             full 20.04.2012

C:\>mminfo -q "client=name,level=full,savetime>-7days,!name='C:\'" -r 
"client,name,level,savetime" -ot
 client    name                             lvl  date
name1      C:\                             full 20.04.2012

C:\>


So i do not expect it to run from the GUI as well. This is NW 7.6.2.5
