In find files there is need for several new options:
1. In "Look in" make button with selection of drives and types of drives to perform searching on: All drives; All local drives; or ability to select particular drive; or ability to select several drives (with Shift and Ctrl) - ex. C:\; D:\; and so on. At the moment it is very uncomfortable to set necessary drives manually.
2. New option "Search in archives" with archive files filter - ex.: *.zip;*.rar or empty for all supported archive types.
3. Ability to use external converters for searching content in MS Office formats (rtf;docx;xlsx;pptx;doc;xls;ppt), Open/Libre Office formats (sxw;sxc;sxi;sxd;odt;ods;odp;odg), Adobe formats (pdf). There is a brilliant free tool for such purposes named xdoc2txt. And it's a pity that here it could not to be used.
4. Extend "Match dates" with new option "Not older than" - XXX minutes or hours or days or weeks or months or years.
