sweetpea there are three other oprions for scanning your downloads:
The Sims™ 2 Content Manager -
http://thesims2.ea.com/getcoolstuff/contentmanager.phpSims2Pack Clean Installer -
http://sims2pack.modthesims2.com/SimPE - scan folder tool -
http://sims.ambertation.de/all three of the alternatives have various strengths and weaknesses - I have found The Sims™ 2 Content Manager to be completely worthless since it provides no useful information in decision making.
I find that only by using combinations of DDO, S2PCI, and SimPE am I able to properly manage my downloaded content with any real precision.
Attention: No software currently available will inform you that a download requires an EP which you do not currently have installed!
