.BAK File Extension

A BAK file is a backup of a bookmarks file created by Google Chrome, Microsoft Edge, or another Chromium-based web browser. It contains a plain text list of a user's bookmarks and folders, formatted using JSON. Chromium-based browsers automatically create BAK files named Bookmarks.bak.

You can open Bookmarks.bak with Microsoft Visual Studio Code (multiplatform), Microsoft Notepad (Windows), Apple TextEdit (Mac), or any other text editor. Doing so will allow you to view the bookmarks and metadata the file contains.

For instructions on how to use Bookmarks.bak to restore your bookmarks in Google Chrome or Microsoft Edge, see above.

A BAK file is a backup of another document or file, commonly created automatically by software programs or by the operating system. It typically contains a copy of the original file and can be restored to the original by replacing the .bak extension with the original extension.

Often BAK files are created by simply appending .bak to the original filename. For example, document.doc may have a backup file document.doc.bak.

NOTE: An example program that uses the ".bak" extension is AutoCAD. Windows may also create BAK files for the System.ini and Win.ini files.

A BAK file is a database backup file created by Swiftpage Act!, a customer relationship management (CRM) program. It contains a copy of an Act! database (.ADF file). This copy backs up the customer contact, company, group, notes, history, and activities data stored in the database.

Businesses use Swiftpage Act! to manage and communicate with their customers. Act! stores all customer-related data in a database file, which Act! managers and administrators can choose to back up. For example, before upgrading to a new version of Act!, a business's IT administrator might back up their Act! database.

Act! saves database backups as BAK files. Typically, these BAK files are stored in a .ZIP file produced during the backup process. This ZIP file includes related Act! data, such as attached documents, document templates, report templates, and saved database queries.

NOTE: Act! was previously developed by The Sage Group.

You can use Act! Diagnostics to restore the database a BAK file contains to Swiftpage Act! (Windows). To do so:

1. Open the Windows Start menu, type actdiag, and press Enter to open Act! Diagnostics.
2. Select Tools → Restore Database.
3. To overwrite an existing database, select Restore BAK file. To add your BAK file as a new database, select Restore BAK file As.
4. Follow the prompts to restore the database your BAK file contains.

After you open your BAK file, you can use the File → Save As... option to save the file as a normal MUS or .MUSX file.

A BAK file is a backup file created by MAGIX VEGAS, a professional video-editing and disc-authoring application. It contains a copy of a VEGAS video project (.VEG file). VEGAS backup files use the extension .veg.bak.

In the event MAGIX VEGAS quits before you can manually save an in-progress video project, the program will automatically save that project as a BAK file. BAK files can be used to recover a project and save it as a VEG file.

Typically, VEGAS BAK files are located in the following directory:

C:/​Users/​YourUserName/​AppData/​Local/​VEGAS Pro

You can open a VEGAS BAK file in MAGIX VEGAS (Windows). To do so, change the file's extension from .veg.bak to .veg and then open the file in VEGAS.

A BAK file is a backup of a Microsoft SQL Server database. It contains a copy of all or some of the files included within the database. BAK files are created using SQL Server Management Studio, Transact-SQL, or Windows PowerShell.

Database administrators use Microsoft SQL Server to store data within relational databases that reside on one or more servers. Because servers can fail and databases can become corrupted, administrators often create backups of their databases and store them on separate servers. That way, administrators can easily replace their original database with its backup if an issue arises. Database backups are saved as BAK files.

Sometimes, administrators create backups that contain only part of a database. These backups, known as differential backups or partial backups, are also saved with the .bak extension.

You can open a BAK file and use it to restore a SQL Server database in Microsoft SQL Server Management Studio, which is included in Microsoft SQL Server. To do so, follow the instructions included in Microsoft's online SQL documentation.

A BAK file is a backup file created by Re-Logic Terraria, a 2D action-adventure and sandbox construction game. It contains a copy of either a Terraria world (.WLD file) or player profile (.PLR file). Players can use BAK files to restore damaged or missing worlds or profiles.

Terraria is a multiplatform exploration, construction, and survival game. The Windows and Mac versions of Terraria automatically create backups of players' worlds and player profiles. World backups use the extension .wld.bak. Player profile backups use the extension .plr.bak.

World backups are stored in the following directories:

• Windows: ~/​Users/​YourUserName/​Documents/​My Games/​Terraria/​Worlds
• Mac: ~/​Users/​YourUserName/​Library/​Application Support/​Terraria/​Worlds

Player profile backups are stored in the following directories:

• Windows: ~/​Users/​YourUserName/​Documents/​My Games/​Terraria/​Players
• Mac: ~/​Users/​YourUserName/​Library/​Application Support/​Terraria/​Players

To use a BAK file to restore a Re-Logic Terraria (Windows, Mac) world or player profile:

1. Remove the .bak extension from the file's name.
2. Place the file in the appropriate game directory (noted above).

The next time you open Terraria, the world or player profile your file contains will appear for selection.

A BAK file is a backup file created by the Android 2.2+ version of Holo Launcher. It contains a record of a Holo Launcher user's custom Android launcher settings and shortcuts. BAK files can be created and imported using Holo Launcher's Backup & Restore menu.

Holo Launcher for Android 2.2+ devices, also known as Holo Launcher for Froyo, is an old Android customization app. Android users use Holo Launcher to replace the operating system's default home screen and customize the way the operating system looks and behaves.

If a user wants to back up their current Holo Launcher for Froyo settings, they can do so using the app's Backup & Restore → Backup option. Doing so saves the user's current settings and shortcuts as a BAK file.

You can open a Holo Launcher BAK file in Holo Launcher for Froyo (Android), using the app's Backup & Restore → Restore option. Doing so will apply the settings and shortcuts the BAK file contains to your Android device.

A BAK file is a backup file created by Taskbar, an app launcher for Android and Chrome OS devices. It contains a record of a user's Taskbar settings. Taskbar users can use a BAK file to restore their settings to a previous state.

Taskbar allows Android and Chrome OS users to add a Windows-like Start menu to their device's screen. This allows users to quickly search for and open applications. Taskbar contains many settings, including the ability to hide Taskbar at certain times, block certain apps from appearing in the Start menu, customize Taskbar's appearance, and more.

If a user wants to back up their current Taskbar settings, they can open the app and select Advanced features → Manage app data → Backup settings to file.... A Save as prompt will appear, from which the user can save their settings as a BAK file. The file is typically named Taskbar-YYYYMMDD-######.bak.

Each BAK file is a Zip-compressed file that contains a .JSON file. The JSON file contains a plain text list of the user's Taskbar settings.

You can use a BAK file to restore your Taskbar settings. To do so, open the app and select Advanced features → Manage app data → Restore settings from file.... Then, navigate to and open your BAK file.

If necessary, you can also decompress your BAK file using any Zip-decompression utility, and then view the JSON data your file contains. (You may have to change the file's extension to .ZIP before you can decompress it.)
