To recover lost unsaved files in Sublime Text 4 on Windows, Mac or Linux we can follow next steps:

  • Don't do any operation with Sublime 4
  • Open the location for unsaved files
  • Find files
    • Auto Save Session.sublime_session
    • Session.sublime_session
  • Make a copy of it
  • Search for deleted version from the OS
  • Restore your files from the Auto Save Session.sublime_session

Step 1: Sublime temporary files location

The first step is to find the location of the unsaved files for Sublime. It depends on the OS:

Default location MAC

~/Library/Application Support/Sublime Text 3/Local/

Default location Linux

~/.config/sublime-text-3/Local/

Default location Windows

C:\Users\myuser\AppData\Roaming\Sublime Text 3\Local

Step 2: Restore unsaved files from Auto Save Session.sublime_session

Next we need to find the right file and version which could store the unsaved files of Sublime Text.

Using Sublime Text will override those files - so it's better to not use it for a moment.

  • Auto Save Session.sublime_session - unsaved files
  • Session.sublime_session - file and folder history

Step 3: Recover text files in Sublime

If you are lucky you will find the correct session file.

These are JSON files which store meta data and unsaved files.

Your unsaved files will look like:

"buffers":
            [
                {
                    "contents": "python game\nshort text\n",
                    "settings":
                    {
                        "buffer_size": 255,
                        "line_ending": "Unix",
                        "name": "python game"

Inside "contents" you can find the content of your unsaved files.

Sometimes you can directly replace the new file with the backup version. This should recover the older state of Sublime.

Step 4: Enable Auto Backups for Sublime

In order to prevent data loss of unsaved files we can use a plugin: Auto‚ÄčBackups.

The official description of this tool is:

Sublime Text 2/3 Auto backups plugin

AutoBackups is a Sublime Text 2/3 plugin, which automatically save a backup copy every time you save or open (if backup file not exists) a file
