There is no obvious way to merge several Microsoft PowerPoint presentations and while many users probably could not think of a reason why someone would want to merge PowerPoint presentations some might find that it can improve the manageability of a set of presentations. Say you received several presentations during a meeting and instead of storing them independently you might find it easier to maintain and access if they all were saved in one file.
PowerPoint Join (via Friedbeef) is a small HTML Application (HTA) that can merge several PowerPoint documents into one. The use is not overly complicated but it requires some work on part of the user. The Microsoft PowerPoint presentations that should be joined have to be in the same folder. The user needs to create a text document that lists the names of all PowerPoint files that should be merged which also has to be in the same directory.
That text document is then loaded in the HTML application. A click on the link here in step 2 of the process will merge the PowerPoint documents and display a blank PowerPoint window afterwards.

That window can be closed. Step 3 will display links to the combined file directly and to the folder were it has been created. The name of the file is combined.ppt. It contains all slides of all PowerPoint presentations that have been merged in the order selected by the user. (All slides of file 1, then file 2 and so on.)
