So, if I have a ton of *.isw files in this folder...
c:\documents and settings\user\application data\#ISW.FS#\Normal

then these are all files which belong to Force Field (ie: Zone Alarm)? I can't seem to find a direct answer anywhere, either here or elsewhere on the net.

Are they okay to just delete?

I'm running Win XP SP3, and ZAX 10.0.250 (both up to date).
