CLI - Command Line Interface
WinFindr has an extensive support for command line usage.

The main WinFindr app supports the following command line parameters:

/NR - No registry search. The same as if using /NRK and /NRE at the same time.
/NF - No filesystem search. The same as if using /NDI and /NFI at the same time.
/NRK - No registry key name search. Does not find matches from registry key names.
/NRE - No registry entry search. Does not find matches from registry entry names.
/NDI - No directory name search. Does not find matches from directory names.
/NFI - No file name search. Does not find matches from file names.
/SUB or /S - Sub-hits enabled mode. Lists all files within a directory, if the directory name is a search match, and all registry entries if their key is a search match.
/AND Performs the search using AND logic mode. In other words, an item is considered a search match if it matches every given search term. If this argument is not given, the search will use an OR logic mode where an item is considered a search match if it matches any of the given search terms.
/Timeout:xxx - Sets the search timeout to xxx seconds.
/Max:xxx - Sets the maximum search results to xxx.
/NoStart - Does not automatically start the search.
