A save file is a digital record of a user’s progress or data within a computer program or game. It serves as a snapshot of the current state of the program, allowing the user to resume their work or gameplay at a later time. Save files are typically created and accessed through a ‘save’ or ‘save as’ function within the program, and can be stored on a computer’s hard drive, external storage device, or cloud storage. They provide a convenient and reliable way to preserve and continue one’s work or play, ensuring that no progress is lost in the event of a system crash or shutdown.
