This package adds file-specific icons to Sublime Text for improved visual grepping. It's heavily inspired by Atom File Icons.
Its aims are:
Provide globally available file type specific icons for each UI themes, whether they provide their own file type specific icons or not.
Workaround a ST core bug, which causes no icons to be displayed for file types an installed but not selected/active theme provides definitions for via tmPreferences files.
Display file icons, even if required syntax definition is not installed.
Display specific icons for files, no dedicated syntax definition exists for.
If you have any problems, please search for a similar issue first, before creating a new one.
Also, check the list of known issues before doing so.

Installation
Package Control
The easiest way to install is using Sublime's Package Control. It's listed as A File Icon.
Open Command Palette using menu item Tools → Command Palette...
Copy folder into Packages directory, which you can find using the menu item Preferences → Browse Packages...
Note: Don't forget to restart Sublime Text after installing this package.
Customization
You can change the color, opacity level and size of the icons by modifying your user preferences file, which you can find by:
Preferences → Package Settings → A File Icon → Settings,
Choose A File Icon: Settings in Command Palette.
Wrong Icons
Sublime Text uses syntax scopes for file-specific icons. That's why icons of packages provided by the community require them to be installed.
See the list of community packages that you may need to install to see the right icon.
Themes
If your theme supports an icon customization you can choose what icons you want to use – provided by the theme (by default) or provided by the package. Otherwise this package adds its own icons only.
Troubleshooting
If something goes wrong try to:
Open Command Palette using menu item Tools → Command Palette....
Choose A File Icon: Revert to a Freshly Installed State.
Restart Sublime Text.
Developers
Bring Support of the File Icon Customization to Your Theme
If you are a theme developer and you want to support a file icon customization, you should:
Remove all stuff related to the icon setup: .tmPreferences, .sublime-settings, .sublime-syntax and .tmLanguage files.
Rename all your existing icons to match these ones.
Add .supports-a-file-icon-customization file to the root of your theme (this is how we check if the theme supports customization of the file-specific icons).
How It Works
In simple terms, A File Icon does the following:
Copies all the necessary files right after install or upgrade to zzz A File Icon zzz directory
Searches all installed themes
Checks if themes are already patched, if not
Patches them by generating <theme-name>.sublime-theme files from a template
For themes those support file icon customization, it provides .tmPreferences files and missing icons by default (user can override icons provided by the theme via "force_mode": true).
The real process is just a little bit more complex to minimize hard drive I/O.

Colors
Colors are bright because they should look good with most themes. However you can change color and opacity level of all icons. See customization.
Source icons are provided in SVG format (Sublime Text doesn't currently support it). They are convert to @1x and @2x PNG assets before each release via python build script py build -i.
