While you are working in a file, you should save it frequently to avoid losing data unexpectedly due to a power failure or other problem.
Click the File menu, and then click Save.
If the program you're using doesn't have a File menu or you can't find the Save command, you might need to check the information that came with that program.
If you are working in a new file and this is the first time you are saving it, type a name for the file in the File name box, and then click Save.
By default, most programs save a file in a logical location for files of its type (for example, picture files are usually saved in the Pictures folder). If you prefer, you can specify a different location in which to save the file.
Click the File menu, and then click Save As.
In the Save As dialog box, click Browse Folders to display the Navigation pane.
Do one of the following:
In the Navigation pane, click the folder that you want to save the file to.
In the Address bar, click an arrow next to a folder name, and then click the folder you want to save to.
In the Address bar, type the full path to the folder you want to save to (for example, C:\Users\Public).
In the File name box, type a name for the file, and then click Save.
Depending on the type of file you are saving, you might be able to add file properties like tags at the time that you save the file. For example, you can add tags and other properties to Microsoft Office documents, JPEG, WMA, and MP3 files, and Searches. Later, you can search and organize files using these properties.
