That's exactly what I did (in C#), and I even used Elmue's cablib:-) It works fine, but it gets a little "heavy" even if I can extract single files without upacking the whole cab.
For now I include the files as binary items and read them as such. I didn't come to think of creating a custom table as Yan suggested - I haven't looked much at custom tables, but if I can get it to work in the same way as reading from the binary table I like that approach and think I'll go down that route. Thanks for all your suggestions and input!
