This Windows application is a resource browser for Cakewalk Project Files (CWP extension), specifically used in Cakewalk Sonar music software. No installation required, just download it and run it. Shows you resources inside a Sonar project file, to help you find the one you are frantically searching for and if, like me, you have many hundreds of project files to search.
It does have a search function, so you can quickly find all the project files that use the audio file "summer recording #47b.wav", or all the projects that have "summer 2017 concert tour backing track" in the project notes, for example.
ProjectScope.exe has recently been updated (March 2017) to support the latest versions of Sonar and use features of Sonar Projects such as the project info image/snapshot.
