Listary is an small (also portable) search utility for windows. It's a 'find as you type' search utility. It's blinding fast, and words very well with thousands of files. It has a minimal UI, Favorites, Recent Menu & Smart options.
Above screen capture shows Listery at work. Notice the small window at the bottom right, that is how Listary words. Just type the file name you want to search and it lists out all possible files, which you can select easily.
It's works beautifully with windows explorer. But it also works with other files managers like Total Commander, Free Commander, 7Zip, FileZilla etc. It also works in the 'Open file' command box.
In the PRO version, you get even more functionality. In PRO you can create 'Project' folders for easier searching from anywhere. Also useful is the Action like copy, paste, open with and many other functionality in the 'Context' menu available in PRO. It's just $19.95 for lifetime, and you can buy it from here.
Hope you enjoy the software. Please share this with your friends, so they can also enjoy it.
PS: It's portable, so it can be installed on any windows, even those with require admin privileges.
