A SESSION file may also be a session log created by an iOS device, such as an iPhone. It contains diagnostic data recorded by an app or service.

More Information

Several iOS apps and services save session logs in SESSION files. Typically, iOS apps and services create SESSION files after a user has encountered a bug. Developers and other advanced users can use these SESSION files to troubleshoot issues with apps or services.

How to view your iDevice's SESSION files

While most users will never need to review their SESSION files, you can access and view them by opening Settings and selecting:

Privacy & Security → Analytics & Improvements → Analytics Data

This will bring up a list of the diagnostic and analytics files stored on your device, which you can then open and view.

How to stop sharing SESSION files with Apple

By default, iDevices share the SESSION files (and other diagnostic files) they create with Apple. If you want to stop sharing SESSION files with Apple:

  1. Open Settings on your iDevice.
  2. Select Privacy & Security → Analytics & Improvements.
  3. Disable the Share Analytics setting(s).

How to open a SESSION file

SESSION files are not meant to be opened by users. However, you can view your SESSION files and the data they contain from the Privacy & Security → Analytics & Improvements → Analytics Data screen of iOS Settings.
