Description
This command defines where to look for files. It accepts three parameters:
- The first parameter is a simple description, used for the GUI to display to the user only. Instead of using plain text, it is recommended to use description templates, which are displayed in a localized version by the scanner GUI.
- The second parameter defines the file name and path. In the standard form, it supports wildcards and path templates, but you can also use Algo-Prefixes to vary the filename matching algorithm, e.g. to use regular expressions. Please note that any pattern apply to the file name only! The file path cannot be varied, but if you specify advanced parameters, the On-Access scanner will simply ignore the path. AP PT
- The third parameter allows you to define more criteria to look for in a file, since the file name itself is rarely unique (just think about all those misleading malware files that attempt to use standard Windows filenames). There is a huge range of advanced file parameters, with different costs, some cached, some not. Using less costly parameters like filesize first is quite recommended to filter the amount of files that are left for the later parameters.
