Index Your Files - Home
Full user review
"Indexes .sql & .rdl files, which Microsoft W7 doesn't!"
T-SQL files and SSRS file CONTENTs are NOT indexed by Windows 7 Search - lamentable omission - but IYF Home does - EXCELLENT!
None so far.
Copernic does index "specialty" files and I used it for years on other laptops, but for a quick and easy install-index-and-search this was a surprising success. With the demise of Google Desktop this is my recommended local file search tool.
