What is a SESSION file

SESSION files mostly belong to PHP by PHP Development Team. A SESSION file contains session information used by various programs. CATIA computer-aided manufacturing software, for example, uses a SESSION file to store information about a model in a work session. PHP web applications also use a SESSION file to store session data. Firefox Internet browser uses a different SESSION file to store information accessible through its Session Manager add-on. SESSION is also the filename extension of an SQLite3 database containing session information used by Sticky Notes. Scratch Live is a vinyl record player emulation software. It also saves session information in a SESSION file.

How do you open SESSION files?

You need a suitable software like PHP to open a SESSION file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your SESSION file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SESSION file directly in the browser:. Just drag the file onto this browser window and drop it.

SESSION file format:

To find out what program is needed to open SESSION files, you need to determine the file format. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the SESSION files is as follows:

SESSION is a very commonly used file extension and includes different formats for different programs. The following file formats are most commonly found in SESSION files:

50% of all SESSION files internally utilize the SQL file format. An SQL file contains a lightweight SQLite database, widely used in application development for storing application related data. If you open these files in a text editor, you will see only illegible characters. The files are 20 KB to 40 KB in size, with a median of 28 KB. The file type is a fairly new file format. The following keywords are characteristic: SQLite format 3. These files are attributed to name, telemetry, storage, cache, cbbc, account, anon and user.
20% of all SESSION files use the popular JSON file format. JSON (JavaScript Object Notation) is a lightweight data−interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The average file size is 4 KB with most files being between 970 bytes and 90 KB in size. Several words can almost always be found in the files, e.g. bug_type, os_version, "log_version" : 2, iPhone OS 14, machine_config, share_with_app_devs, "region_format" : "US" and "scheduled" : true. Files like these are sometimes connected to sessions and power.

All other SESSION files (30%) have no consistent format, the following 7 formats can be found: Session Manager Firefox Backup, plist, XML, vrsn and echo. They are often associated with backup, telegram, uploader, scrappy or parent. Drag & drop your file here to see the file format and a preview of your SESSION file!

How to solve problems with SESSION files

Associate the SESSION file extension with the correct application.
Update your software that should actually open session informations. Because only the current version supports the latest SESSION file format. Search, therefore, e.g. on the PHP Development Team manufacturer website after an available PHP update.
To make sure that your SESSION file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
