Rainbow Folders (RF) is an easy to use desktop program, which allows you to change the color of the icon representing a chosen folder to any color you like. Why is this necessary? Mainly to boost yours computer usage speed & skills.
When you´re exploring a directory which contains lots of subdirectories in Windows Explorer you can easily commit a mistake, e.g. by clicking the folder´s icon which has a similar name to the one you really wanted to go to. With the folders marked with the colors of your choosing, you won´t make any mistake and after some time you´ll be clicking the right folders by impulse.
For example, you can use RF to mark subdirectory TEMP inside C:\WINDOWS\. Then after going to the system dir you won´t be searching the TEMP dir on the whole screen, but at the start you will click e.g. the eye attacking bloody red folder. And now the best part: you can colorize an unlimited number of folders – each into a different color. So you can e.g. colorize all important folders red, then colorize all frequently visited folders to green etc. Also the effect of colorizing folders is not only visible in Explorer but in whole system, so also in any directory selection tree, and open/save dialog in any Windows application! But changing colors is not everything you can do with help of RF, you can also set an extra warning when someone tries to delete a colorized folder, and optional text that will ´pop up´ when the cursor stops above the folder´s icon for a while.
