Search Path: The search path in specified in the path field of the Main Window or the Script Dialog. This is the upper level path where Search and Replace begins the search &/or replace operations.
Notes:
To search all local hard drives specify 'Local Hard Drives' (no quotes). To search shares you have access to on a UNC path, specify the UNC machine name (example: \\server10\ would search \\server10\c\ and \\server10\ docs\ if those are shares you have access rights to).
Use the file mask, filters, and advanced script settings to further specify which files will be processed.
Don't forget to enable 'Search Subdirectories' if you want to search files in paths below the entry in the Path field. To do this, click on the Search Subdirectories button or activate from the Flags Menu.
You can also drag n drop a folder from Explorer into the Path field to quickly enter a path.
