What is a PRDX File Type?
The PRDX files are saved in a proprietary format and are the main presentation file type, a slide presentation program similar to Microsoft PowerPoint, included with Microsoft Office. The use of PRDX files is the same as the use of .PPTX files by Microsoft PowerPoint.
Typically, presentations are saved as PRDX files, but there are several other formats available. It can be saved as .PRV or PRVX templates for repeated use, .RTF files as a text outline, or .PPT, PPTX or .PPSX PowerPoint files. They can also be exported to other formats such as .PDF, .HTML, .PNG, .JPG, .TIF, .BMP, .WMV or .MP4.
The PRDX files replaced the PRD files, which were used to store the presentations of older versions of Presentations.
