Notes about the SAVEDSEARCH file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The SAVEDSEARCH file type is primarily associated with 'OS X' by Apple Inc.. Spotlight is a search technology that is tightly integrated with a fundamental part of the OS: The file system. Every time a file is created, saved, moved, copied, or deleted, the file system automatically ensures that the file is properly indexed, cataloged, and ready for whatever search query might be issued--all in the background. Spotlight saved searches, or Smart Folders, are simply XML files with a .savedSearch extension.
