Saving your work is one of the simplest activities in PowerPoint, and it is also possibly the most vital. Many users have burned their fingers as a result of not saving their work in a timely manner, resulting in the loss of hours of hard labor. The basic procedures for saving a presentation are as follows.
Step 1: Launch the Backstage view by clicking on File. Here select Save.
Step 2: Type the file name in the Save As dialogue box and click "Save."
Step 3: The.pptx file format is the default. Choose one of the file types from the "Save as type" dropdown list if you want to save the file with a different name.
If you're working on a previously saved file, the "Save" option in the Backstage view will save it in the same format as before, with the same name. Use the Save As option to modify the format or filename of an existing file and save it as another file.
