Some applications particularly Adobe Photoshop, Illustrator, Microsoft Word and a few others display an overwhelming number of file types in their Open and Save As dialog boxes. Often it takes a long time to locate a file type you want to save as or open because it’s buried deep in a list of other file types, most of which you never use.
Formats Customizer is software that helps you clean up the drop down menu under File Types in Open, Save, Import and Export dialog boxes.
Currently supported applications include:
Microsoft Office Word
Microsoft Office Excel
Microsoft Office Power Point
Just select one of these application from the Application drop down menu and uncheck the boxes against the file types you want to hide. Simple.
