Editing large files on Mac OS X [closed]

Solution 1:

Have you tried Vim? It's the only editor I use :-)

Edit: It seems to depend upon a couple of factors. I used Vim with large CSV (i.e. text-based) files and that worked great. YMMV :-)

Solution 2:

If, as you say, only really need to get an idea of the structure try opening the document in Console. Believe it or not, I'm able to view files as large as 15GB (MAC OSX 10.7.2)

Solution 3:

HexFiend is designed to read files of any size, but you'll need to work using fixed-column character wrapping and no newline detection.

Solution 4:

If you just want to have an idea of structure, how about browsing with more or less?
