The issue is that there index is corrupt or rather there is data missing from them. Rebuilding them causes the server to crash so I wanted to try and extract the data so I could compare it against the database to see what was missing and add it. > > Is this a job for pack/unpack? > > Could be, especially if you know (or can determine) the file format. > Do you have any documentation on the program that created these files, > or one that reads them?

I think your right. I was hoping that perhaps they were made with something like pack or storable which would make the task possible. > Good luck with it! Thanx for your time.
