Large Text File Viewer 4.1

http://www.swiftgear.com/

No “installation” is needed, so again it is “portable” and USB friendly.

…designed for viewing large (>1GB) text files.
…enhanced for searching…
…allows the user to change display parameters, which include:
o font, font style, and font size.
o colors of text, selected text, and URL.
o background color and background image. (The user may use any JPG or BMP file as the background image. A sophisticated algorithm is used to soften the image and then blend the softened image with the background color perfectly.)
o tab size.
o automatic detection of URL addresses (namely HTTP, FTP and email addresses).
…program remembers recently opened files.
…remembers the window position/size of the previous run.

Sorry, all these are Windows applications…not as familiar with Linux options for you.

I’d encourage you to check out FoxitReader.

http://www.foxitsoftware.com/pdf/rd_intro.php

It has a free version, and is “portable” so you can keep it and your PDF’s together on a USB stick. And it is lightning fast. Really, really fast. I’m not exaggerating! It also supports annotations and highlighting of the PDF.

Great for reading “on the fly” or if you need to borrow someone else’s system.

You might also want to look into Cool PDF Reader (free).

While it can open and view PDF files, it is really strong it the ability to convert PDF files into other formats. Nice utility tool.

But for reading/viewing PDF files…hands down…Foxit Reader.

Nothing else comes close in my opinion.
