Search Companion Starts If You Double-Click a Folder or Drive

If you double-click a drive or folder, Search Companion may start and the drive or folder may not open. ‘Search’ will be the top most in the right-click context menu for a folder or drive. This usually happens after adding/modifying the  File Folder or  Drive entries via the Folder Options File Types dialog, as an attempt to add additional context menu items such as Command Prompt here, Print Directory for folders or drives.
