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.)
