How to Open ISF Files
By Fraser Sherman
If a file has the ISF extension, it was made using Inspiration software. Inspiration creates flowcharts and diagrams. It's also useful for writing, outlining and creating presentations or brainstorming ideas. The Inspiration Software company says it's primarily a tool for education, but adds that adults will also find it useful.
Get Inspired
You have to have Inspiration installed on your computer to open an ISF file correctly. Trying to rename the extension to open it with another program will only corrupt the file. Once you've installed the software, just double-clicking on an ISF file should be enough to open it. You can order Inspiration from Inspiration Software's online store at the corporate website (link in Resources).
