How to open Very Large text files

I've got a text file that is about 941 MB - almost a Gig.

How can I view the contents of it?  If I try to open it with notepad or Edit Plus it chokes.

Adding RAM to the PC is not an option - I need to open this on a machine with 1/2 gig of ram.

Splitting the document up in to about 100 MB files would be ok with me too then I could open them individually.  Don't know how to do this either.

My platform is Win 2K.

Thanks much,

Dear aflat362,

You may think about file splitting

Have you tried opening that in MS word or Word pad .. Is that file with extension .txt ?

Thanks,
Sunray

sunray_2003,

I have tried opening my file in both word and wordpad - they both choked.
My file has a .log extension but its content is plain text.  Could just as easily be a .txt file.
Thank you for the recommendation of the splitter software but I think the editor suggested by
chicagoan will better suit my needs.

chicagoan,

The app you recommended looks promising.  I'm seeking approval to download and install it on my workstation.  Our shop is pretty tight about new apps and stuff.  Hopefully I'll get approval and then I will be able to work with this file.  I'll give you the points after my goal is complete.

Thanks,
aflat362

Here's another program that claims to open files of any size.

To give an update,

I requested a download of the Programmer's File editor and was effectively denied - gotta love the politics of the work place.

A couple of our software guys are trying to figure something out.  I have a feeling that they'll eventually give and allow the download.

I'll let you know if anything comes up

I found this utility extremely fast and efficient. Opens log files of any size in a fraction of time.

And importantly its free.

one could easily use the DOS commands 'more' or 'type' to scroll through the content and, if needed pipe it into a file or something

I downloaded the "Large-Text-File-Viewer" utility recommended by beepeerao and it works like a charm, I opened a 700 MB text file in seconds on an old Windows XP notebook. But, while starting the open file dialog window of the LTFViewer utility, Online Armor advised to block it because of its unusual behaviour, as it was trying to access hard disk directly (using a randomly picked data folder of mine).
Here is Online Armor's warning:
======
<<LTFViewvr5u.exe wants to access hard disk directly using device "\Device\HarddiskVolume2\RandomFolderOfMine\:{4c8cc155-6c1e-11d1-8e41-00c04fb9386d}:$D
What does it mean?
Direct disk access is dangerous and unusal action
Malware, viruses and rootkits can use this to install themselves to a system or to access sensitive data
What should I do?
Block
Until you are sure this program is safe, you should block it >>
===========

 LTFViewer also tried to gain access to system32/SVCHOST.
However, I verified it with MalwareBytes', SpyBot and McAfee and thet didn't find anything. I also submitted both the zip file  and the executable LTFViewr5u.exe to www.virustotal: all their 39 online scanners say it is clean. I also verified the MD5 is the same as for the file from the author's web site (SwiftGear.com).
