How to copy file name of currently opened file in sublime text 3?

You can do this if you have the SideBarEnhancements plugin installed.

1. Open up the command palette with Ctrl+Shift+P (on Mac it is ⌘+Shift+P)

2. Type File: Copy Name and press Enter

The file name has now been copied to your clipboard.

Setting a hotkey for this command:

1. Go to your Key Bindings -> User file

2. Add this line to your file: { "keys": ["ctrl+shift+l"], "command": "side_bar_copy_name" }

3. Change "ctrl+shift+l" to whatever command you want to use.

In Sublime Text 3 and 4, you can simply right-click within the file body itself and select Copy File Path.

Using the SideBarEnhancements plugin is also an option when you're browsing through files contained within folders that you have added to your project (that show on the lower part of the sidebar). There, just right-click on the file and select Copy Path or Copy Dir Path.
