3. In the window, select what file type you want to save the document as from the drop-down menu. You will have various options depending on your operating system and software.
4. Choose a place to save the document (such as a folder or a desktop).
5. Click “Save”. The document should now be saved with the correct file type.
6. Open the document in its respective program (word processor, photo editor, etc.) and make sure that the file type is indeed correct.
7. If it is not correct, repeat the above steps and make sure to select the correct file type before saving.
It is important to remember to check the file type after changing it, as certain information may be lost when switching between file types. Additionally, some file types may be incompatible with certain programs, so make sure that you are selecting the appropriate type for your purpose.
