What program is creating such a large file? This could simply be not having enough memeory to open the file. MS Word and Excel will open very large files but not sure if it can handle a file this size.

Well I was mistaken about MS Word the 2000 version seems to have a 32MB limit.

Hmm Interesting I am using Win2000 and I changed my virtual memory to 2GB and Wordpad did open a file that is over 550MB in size. Also there needs to be enough disk space for housing any temp file Wordpad wants to create. So I would say you would need at least over 3GB of free disk space to create such a big swapfile (virtual memory) and for the temp file.

To change your virtual memory settings go to My Computer > Propeties > Performance and click on the "Virtual Memory" button and then click on "Let me specify my own..." and in both boxes type in 2000 and click on the "OK" button and then reboot. Befor opening the file close all programs except Explorer. Even doing this you may not be able to achieve opening the file because the System Resources my run to low and there is not anything you can do about that.

The other thing to keep in mind that it could take a long time before the file completely opens. And scrolling could become a nigthmare.

Some sort of segmentation might be the answer.  We used to call them "records"!

What is in this .dat file?  Is it video data, or just a huge Text file?  You can use UltraEdit (www.ultraedit.com) to open huge files.

I looked into the virual memory setting. it is now set to min-o, max- no max. Windows manage with a setting of 27716mg. How will changing this to 2000 make it larger?

Glad to help!  UltraEdit is a pretty slick package...if you do programming, it has automatic syntax highlighting for C, C++, HTML, Java, etc and has a dictionary feature.
