Nice. Opened a 800+ Mb log file lickity-split. Lacks bells and whistles but for viewing very large text files it's just what you need. Every other editor choked on my log file. I didn't even notice a performance hit my pc.

Loaded a 27.5mb file very fast but is slow in searching. In fact search stops well before end of file not findin a string taken from near the end.

Great for viewing large text files, such as apache log, can even search for text. But do not dare to open large binary files with it, crazy things will happen ;-) Made test on a 100mb file, where the first 99.99MB was 0s and then simple "hello world". It failed to open it, CPU was constantly at 100% load, it allocated and released memory like crazy, but nothing really happened.

It could open file up to 1Gb ( I didn't try larger file). How do I edit the file? There is no option to edit the text. Does anybody know how to edit the file or any other editor which will be able to open such huge files and be able to edit them? Many thanks for help.

I wish i would have found this program first. I was dealing with a 1.2 GB report. I needed to find strings in the file and couldn't open it, search it, or split it with any programs that i could find. This program is Great!

I could not find a better editor. I thought I'd never be able to debug the issue as the file was too large.. but this editor did it. Thanks.

Tried on Vista Business. Worked great on a large file (33M). However, I tried working with a 200M file (Wordnet 3.0 sql export file) and things were much slower - I think the main reason is that the file has very long lines. Anyway, much better than Notepad, WordPad and Notepad++ when working with large files Good luck!

This program opened a 400meg mailbox in about a minute! Much better then notepad...

The program crashed on me too but only when I tried to search. I discovered that you have to wait for the entire file to load before searching. Watch the status line at the bottom while it counts the number of lines in the file. In my case the file was 800+ MB, nearly 12 million lines. On a dual core Athlon 64 4400+ it took about a minute (I didn't time it) to load. Once loaded though, I was able to search just fine. The only thing I didn't like was the text size came out huge. I chose a different font - Lucida Sans Unicode 8 pt - looked a lot better.

it managed to open THE ENTIRE HUMAN GENOME! thats 90M lines! lol that was the high point in my day

I just opened a file that I didn't believe any program would ever be able to open; over 25GB text file with 248,290,728 lines. It took quite some time for it to open, but it had no problems. What’s more, it only used 13Mb of system memory to accomplish this. I will be putting this on all of my servers. I regularly need to open log files of 100+ Mb and other programs are annoying at best when they take 5 min to open. This program takes moments to open the same files. Thank you so much for this exelent application.

Opened and displayed over 30M lines. Great software!! Thanks.

I have a 128MB asc file that it took about 10min to open.

The file appeared on the screen and when it got to 1,640,002 records the program terminated saying, "it has encountered an error and must close".

Thanks, it does exactly what I need. I just opened a 360 MB size file (5 M lines) and searched thru it for a specific line. quite fast and reliable. Keep going !!
