PowerPoint Join

PowerPoint Join is a software application with a pretty self-explanatory name - it lets you merge Microsoft PowerPoint files. The tool can be seamlessly handled, even by less experienced users.
This is a portable application, so installing PowerPoint Join is not necessary. It means that you can store the app on a removable device (like a USB flash drive), save it to any computer and directly run its executable file.
This way, you can always have PowerPoint Join with you when you're on the go. Additionally, the Windows Registry is not updated with new entries, and no leftover files can be found on the hard drive after program removal.
The interface of PowerPoint Join is based on a small, standard window where you can import a plain text document by using only the file browser, since the 'drag and drop' functionality is not included. This text file should list the charts to be joined, and must be stored in the same directory as the respective PPT items.
Merging PowerPoint documents is seamlessly done, with just the click of a button. Plus, you can open the output files right from the main application window. PowerPoint Join has a good response time, runs on a low-to-moderate amount of system resources, and quickly finishes a task. However, the tool has limited features and has not received any recent updates.
