Non-Document Files

I must first say that your software is awesome! I am currently scanning/digitizing all of my personal data. My question is can I drag a non-document file, in my case an old Turbo Tax file, into my database? I have scanned all of my paper copies, but would like to store the xxxxx.tax files in the same database. I am trying to keep everything in one database. If I do drag this file into DTP, can I drag it out in order to use it in another program?

Thanks

That should be possible if you enable the import of unknown file types (see Preferences > Import).
