Edmond,

I don't know if this is an answer, but I have a product called ZipMagic installed on one of my PCs and it does work some magic... It will let a file that is ZIPped be accessed as if unzipped by most applications. It works (at least the very limited times I've tried) with .DBFs and VFP. It does NOT go through an UNZIP step internally, but rather (it claims, and appears to) handles each record as it is read.

I think it cost me around $39. It does install itself PRESUMPTUOUSLY (in my opinion). For instance I suddenly found a new bix beside the minimize box, some new menu options in various places and a startup/Systray icon. And I have found that I have to remember to turn it off when I install software (like VFP) that has .ZIP files as parts of its install.

It might be worth a try. I'm guessing they have a trial version available. www.mijenix.com.

Good luck

>I have to create a table of 35 millions plus records. The table is to be populated from 850 fixed length text files. I get about 1/3rd of the way through with the imports and I hit the 2 Gig limit for Visual FoxPro tables.

>Other vendors have this data is some sort of file structure that only takes up about 450 Megs. They distribute this data (in .dat format whatever that is) via a CD-ROM and access it directly off of the CD via their apps on the fly without any major writing to the hard drive. They can access the data immediately upon demand without any obvious decompression. For me, just trying to zip the 2 Gig text file takes forever and slows the computer to a crawl.
