I'm trying to compare 2 large text files around 500MB each, I've tried to use Notepad++, Textpad, VIM etc and couldn't get them to even open the text file. Either that, or the editors that DO work don't have the compare feature.
I need to see what changes are made in those 2 text files, that's why I need to compare them. Does anyone have any suggestions?
diff file1 file2
Are the files supposed to be very similar? Use a diff program instead of an editor; since they specialize in showing the differences, they are often more capable of handling large files.
The page at http://drupal.org/node/324 has a list of diff programs for Windows. If you are using Unix or Linux, you probably already have diff installed.
If you need an editor, I know that Emacs can be configured for files as large as this, but I haven't tried it myself. More info at http://www.emacswiki.org/emacs/EmacsFileSizeLimit
Winmerge at http://winmerge.org/
exactly what you want.
Using UNIX/LINUX diff file1 file2 is not practical with large text files.I spent some time looking into solutions today and i wanted to share my finding with you. There is Open Source Project Meld http://meldmerge.org/. It is available on OS X, Linux and Windows platform as well.
If you prefer using notepad++ there is plugin available to download:
Open notepad++ -> Plugins -> Plugin Manager -> Show Plugin Manager -> Find plugin named "Compare".
JujuEdit opens large file and it does not load them into memory. It does not compare features.
I opened a file 1G byte in 2 seconds or less.
It has binary mode.

I have a bootloader project and an app project within the same workspace in Eclipse.
I'd like to merge the hex files of theses two project into one single hex, so that I can flash in my MCU both project at the same time.
I know this is possible using some tools (https://www.keil.com/support/docs/2666.htm), but I would like that the merge process happens in Eclipse using a post-build command or else.
Thanks
Intel hex are just text files, you can merge them manually in any text editor by using simple copy/paste. Grab the data rows only from one of the files.
This assuming that there's no CRC on the program as whole. Also, you probably shouldn't have multiple rows with the same address in the same file or you might confuse some tools.
I'd recommend doing this through a diff tool such as for example WinMerge, or the one integrated in your version control system. Once you have it working you could write a file handling script for merging them automatically.
Whenever I tried to open the .bin file in Windows, (and also eclipse), it is like this, so I cannot read anything. I am using it to test Buffer Pool, but I cannot read, so I cannot know that is the test was successful or not. It is same when I opened it wil notepad.
I am using U.S. window, but installed Korean language, but I still can read/write English well.
Extension of file name ".bin" stands for "BINARY". That means your file may contain not-printable characters as you saw.
If you want to see the contenst of binary files, you should use 'Hexadecimal Editor', 'hex editor' in short, instead of text editor like notepad.
http://en.wikipedia.org/wiki/Comparison_of_hex_editors shows many hex editors.
Some software may be able to handle your .bin files. It depends that the origin of that file.
does anybody know how to open programmatically (not manually) the compare merge editor simply passing two file names? Lot of search everywhere but haven't found anything.
Thanks for any help
If you only need a compare/merge editor I suggest Winmerge or P4Merge, both are free and you can call them from command line.
Is there a diff tool that allows you to paste two segments of text and get a diff? I can't use an online tool because I'm dealing with proprietary data, and I haven't found a tool that provides that feature.
Try WinMerge. It'll do that.
Steps:
Download and install winmerge
Open WinMerge & Create new <CTRL+N>
Paste into left & right, then refresh <F5>
In case anyone comes here looking for a tool for Macs that can do this, it seems that there are two tools that can do just this.
Beyond Compare, the Mac version is currently in beta.
Kaleidoscope app
Copy first text
File -> New from Clipboard
Copy second text
Edit -> Paste to comparison
Unfortunately, it doesn't seem to be possible to change the texts once they've been pasted.
There is also a similar (closed) question (the question itself was for a Mac tool, but at least one answer has an alternative diff tool for Windows):
Diff tool for Mac without saving text to files
For those who use Atom, there’s the split-diff package.
KDiff3 can do that too. On startup just Cancel the open dialog and than copy&paste snippets into the two panes. It immediately (re)computes their diff.
Notepad++ makes it really easy to do that: paste first text, open new tab, paste second text then Plugin > Compare > Compare.
Make sure you have the compare plugin installed.

I think this might be what you're looking for - Line Diff - it's a online tool that takes as input two snippets of code/text, diff them and then render a nice github like html page (permanent or temporary stored) that you can then share with coworkers.
I used BBEdit (Mac OS X):
paste your snippets into 2 separate new documents (without saving)
go to search → find differences
using the clock icon, pick your new documents
The app has a subscription model, but this doesn't seem to be a premium feature.
You can try online tools
it's good
https://www.diffchecker.com/
Or you can try KDIFF3 its also a good tool
http://kdiff3.sourceforge.net/
also you can try online diff tool , maybe it's useful to you.
I have a partially corrupted MS-Word file which I'd like to inspect in the byte-level.
HexEdit is pretty nice (allows you to edit files too)
What you need is a hex editor. Some text editors can run in this mode. I always used PSPadfor this
As always there's emacs, hexl-mode allows you to view and edit hex-files.
I like the freeware hex editor xvi32 for this kind of task.
I'm sure there are many, but Ultraedit does this.
If you have Visual Studio installed, you can add the .dat extension to the file and open it in Visual Studio to get a hex/ASCII display.
010 Editor is nice for looking at files that follow some template, it'll try to turn the raw data into meaningful labeled values for you.
Take a gander at BeyondCompare for file comparisons; version 3 has comparisons for Word files as well. You'd be surprised at how often you'll use it once you have it.
