After opening Access, you will be presented with the window shown below. Select one of the first two options if you are creating a new database, or the third if you want to edit an existing database.
Blank Access database
Unlike Word documents, Excel worksheets, and PowerPoint presentations, you must save an Access database before you start working on it. After selecting "Blank Access database", you will first be prompted to specify a location and name for the database.
Find the folder where the database should reside in the Save in drop-down menu. Type the name of the database in the File name line and click the Create button. Note the .mdb extension. If you forget where you saved your file, do a search for it by typing *.mdb in the search box. To search click Start / Search.
