Status Bar File Size

Displays file size in the Sublime Text status bar. Where possible, the size is queried from the file system. If this information is not available -- e.g. for a buffer that was modified and not yet saved -- the file size is estimated from the buffer contents and chosen encoding.

Additionally, the file size after DEFLATE compression, as used by gzip, can be enabled in the settings.

Installation

Use Package Control.

This package only supports Sublime Text 3 and 4.

Configuration

The default and user configuration files can be accessed from the Sublime Text menu bar, Preferences -> Package Settings -> Status Bar File Size.
