You can actually store the add-in in almost any convenient folder, but when you use the Add-In Library, it’s easy to find the add-in from within Excel when you install it. You can get there quickly by pressing Win+R (Win = Windows key), typing %appdata% in the Run box, and clicking OK (which opens the Roaming directory), and drilling down to Microsoft and then AddIns. Unzip the file, and store the add-in in the User Add-in Library, which is C:\Users\USERNAME\AppData\Roaming\Microsoft\AddIns\ Very often, an Excel add-in is packaged in a zip file. An Excel add-in can also be opened like a regular file when you need it, without installing it, though it is still hidden. The add-in can be installed, which means it opens every time Excel opens, so that its functionality is always available. The add-in workbook itself is invisible, though it has one and often more hidden worksheets, where information related to the add-in may be stored. An add-in usually has some user interface elements, such as buttons on the ribbon or on context (right-click) menus, so you can access its features.

An Add-In is basically a workbook containing some code, that has some other unique properties.

A lot of Excel procedures are packaged in Add-Ins.
