I am trying to open the skype .dat hex files and I would like to know if I can use Sublime text instead of the other 'dedicated' hex editors.

Sublime text is one of my favorite editors. You can extend its capabilities by using plugins.

I use its plugin HexViewer to view hex files. http://facelessuser.github.io/HexViewer/

  • In Sublime Text, press ctrl + shift + p (Win, Linux) or cmd + shift + p (OSX) to bring up the quick panel and start typing Package Control: Install Package. Select the command and it will show a list of installable plugins.

  • Start typing HexViewer; when you see it, select it.

  • Restart to be sure everything is loaded properly.

    Seems really good but frustratingly I can't figure out how to open it after it's installed. The documentation doesn't tell you the keyboard shortcuts, nor are they listed in any key settings file anywhere. May 29, 2018 at 5:36

    Lack of documentation for opening plugins seems to be a common theme. I managed to find it by going to Tools > Packages > Hexviewer > Toggle Hex Viewer

    I used this happily but now it says "Can't find package HexViewer" every time I open it and I can't find it in the install menu. Was it removed?

    Yes, but how can you edit?

Once the HexViewer is installed in sublime text, press "Ctr + Shift + P" to open the "command palette" now just type "HexViewer: Toggle Hex View", you can now see the hexadecimal code as well.

This can be done without installing any plugins. Simply open the file and select File -> Reopen with Encoding -> Hexademical.

HexViewer has a richer UI and additional features, but this works out of the box.
