What is a PRO file?
A .PRO file is a multi-purpose file extension used by many different software applications. Because the .PRO extension is short for "project," "profile," or "protocol," it is a popular choice for software developers. Some common formats include Qt Project Files used by the Qt Framework, KiCad electronics projects from KiCad, home design projects from Punch! Software, and the Adobe Proto Design File from Adobe Systems. A .PRO file can also store 3D CAD data, song lyrics in the ChordPro format, or system protocols for medical devices.
How to open PRO files?
A .PRO file can contain plain text, a ZIP archive, or proprietary binary data. You must know the exact format to open it correctly. A software developer opens a Qt .PRO file using a simple text editor or Qt Creator. An architect opens an ARCHline.XP .PRO file using ARCHline.XP. If you do not know where the file came from, guessing the correct software is difficult.
