SonicFileFinder is comparable to ReSharper’s “Go to File” feature; both let you search for files in the projects of the currently loaded solution. One of the key differences is that SonicFileFinder remembers the search term whereas in ReSharper you start from scratch each time. SonicFileFinder recreates the result list blazingly fast and if you want to enter a different search term, you can start typing immediately.
You’ll learn to love SonicFileFinder’s approach when you have several files in the result list and you don’t quite know which one may be the one you are actually looking for. You open a file e.g. by pressing Enter, see that it’s not the one you wanted, hit the hotkey (Ctrl+Shift+Y by default) again and simply choose another one from the list – without having to enter the search term again. Alternatively, you could also select multiple files and open them at once.
SonicFileFinder has a couple more nifty features; head over to the SonicFileFinder website for the complete list and some screenshots that give you a good idea what this excellent Visual Studio extension has to offer.
