# Save your inspection session

You can save your data inspection session for later use and sharing. After you have made changes to the generated data and you exit the application, an inspection icon (![Inspection Icon](/files/kpRCXi0pR58f5Mfmdhdu)) appears on the step in the transformation canvas to indicate it has a remembered session. When you save, this session gets stored as a Kettle transformation (`.ktr`) file. The session can then be restored by reopening the saved file and re-inspecting the step.

**Note:** When opening older saved file formats, they will be automatically updated to the current format. After this conversion, the formats can only be opened in the current version of PDI.
