Comparing large xml files

Question

Hi, could anyone assist me with this. I need to compare two beefy xml files 40mb each (ok not that beefy), but notepad++ croaks on this. Can anyone suggest something that will help (windows only).

I read a similar thread: http://stackoverflow.com/questions/159521/text-editor-to-open-big-giant-huge-large-text-files

but this only talks about opening large files. Comparing and opening are 2 very different animals. Can anyone suggest anything that will help

Thanks Craig

Answer 1

c:\WINDOWS\system32\fc.exe <firstfile> <secondfile>

? :)

Answer 2

• http://gnuwin32.sourceforge.net/packages/diffutils.htm (command line)
• http://winmerge.org/ (GUI)

Answer 3

kDiff3 worked fine for me to compare files greater than 10 MB - It's quite light-weight.

Answer 4

I always use DiffMerge or ExamDiff (Pro version) for my Diff needs. I haven't tried them with files larger than 2 MB, but you might want to give them a try.
