Large Text File Viewer was fully tested by TopShareware Labs. It does not contain any kind of malware, adware and viruses.
This program was designed for viewing large (>1GB) text files. It uses little memory and is able to open a gigabyte file instantly. The user may perform high-speed complex text search by means of plain text or regular expression.

This program opens files that are currently being written by other programs, and automatically checks and reads the files if new contents have been appended.

The program supports mouse wheel, word-wrap, and view split. It recognizes URL addresses (namely HTTP, FTP and email addresses). The user has full control of the display setting, which is saved automatically and associated with filename extensions. You may use drag-and-drop to open a text file. The program remembers recently opened files.

This program opens and displays both ANSI and Unicode text files. And because only Windows NT, 2k and XP support Unicode, This program runs only on these platforms.

    Excellent, but missing one important feature
    This is an excellent tool; simple and effective. However, for those who want to use this tool (e.g. to view large log files), displaying line number is an essential function, so much so that, without this function, the value of this tool is significantly compromised.

    very good and very responsive author.
    I had a file with very very long lines that failed and he look for the bug and released a new version. The best viewer for very large text file.

    Works as advertised for 11GB XML file
    The file took about 5 minutes to unzip, but less than 1 second to open in this file viewer. Of course, it takes about 5 minutes to load the whole thing (it''s still loading as I write this), but of the text that HAS loaded you can search through it just fine. Obviously, text that hasn't loaded yet cannot be searched. You can see in the program''s status bar where it is in the loading process.

    good, can do some better
    The application seems to do very well what it's designed for (that is, viewing and not editing). Here are some hints to improve it: when the user tries to do a search and the file is not fully loaded yet, warn about that instead of going back to the first match of the text to search; don't close the application when the user (possibly by mistake) presses the ESC key; remove some skulls from the background ;-)

    Opened a 6.3 gigabyte file with 141 million lines. Nothing else I tried would open the file. The file opened immediately then took a few minutes to load all the lines. The peak memory usage was 79 meg. I plan to use it for viewing large data and log files. Aboslutely fantastic and it was free.

    Great Tool~
    This is a great tool, really helped me to open a big file. The only thing is that it doesn''t support UNICODE The reason for slow search speed as mentioned below, is due to the large file size. If you observe the line counts, it jumps for about 10,000 lines per second, that''s not too bad. I guess there isn''t any instant tool for everything.

    Very Good, Large, Free File Opener.
    This is a real good file opener which opens large text files. I always use to split the large file, until someone told me that even editor are available to open such large (>1 GB) files. Very Impressed and it saved me a lot of time. thanks to developer for sharing this free tool. Bless you.

    Incredibly fast tool
    I cannot believe how fast this tool can be. 1.2GB file (16.8 million lines) opened in less than a second. I thought I was dreaming :) Not to mention the split screen search function, hyperlink detection, background customisation, etc. I have been looking for a long time for something like this, but it exceeed my expectations.

    Worked fine on a 3.5 GB text file
    This worked absolutely great for me. It opened a 3.5 GB file in a few minutes, using little CPU and memory. Excellent tool.

    It does what I need it to do
    Loaded a 1.1GB text file (with 5.8 million lines) just fine. Thank you!

    opened 5.75 gigabyte file
    Required no software install. Executable runs directly from unzipped folder. My AV client (Symantec) passed it as clean... no virus or spyware. Took it about three or four minutes to open a 5.75 gigabyte text file with over 2.9 million lines. I did not need to edit the file, just needed to verify some records in it before uploading it to the mainframe. Works well enough for me!
