What is a .LOCALSTORAGE file?

A .LOCALSTORAGE file is a type of data file used by web browsers that are built on the WebKit engine, such as Google Chrome and Apple Safari. These files are used to store various types of information locally on your computer. This can include browser settings, data for different browser extensions (also known as plug-ins), and other types of local data that help improve your browsing experience by allowing websites and extensions to quickly access stored information without needing to retrieve it from the internet every time.

The data inside a .LOCALSTORAGE file is stored in a format called SQLite, which is a popular database format used by many applications for handling structured data. Because the data is stored in a database format, you can use SQLite database management programs to view or manage the contents of these files.

To open a .LOCALSTORAGE file, you can use web browsers like Google Chrome or Apple Safari, since these files are typically associated with these browsers. On devices that run iOS, such as iPhones or iPads, Apple Safari can also handle these files.

.LOCALSTORAGE files are particularly useful for browser extensions, such as games played within the Chrome browser. For example, a game like Angry Birds might store your game progress and settings in a .LOCALSTORAGE file so that you can pick up where you left off each time you play, without having to start over.

For users of Google Chrome on Windows, you can find these .LOCALSTORAGE files in the directory path: [user]\AppData\Google\Chrome\User Data\Default\Local Storage\. If you are using Chrome on macOS, the files are located at: ~/Library/Application Support/Google/Chrome/Default/Local Storage/.

In summary, .LOCALSTORAGE files help enhance your web browsing by storing important data locally, making it quickly accessible and improving the performance of web applications and extensions.
