FolderIconDrop

If you ever wanted to change the way a certain folder is displayed on your computer, you might have tried doing so manually, from the object's "Properties" menu.
However, there's an easier way to help you do that by turning to third-party software solutions such as FolderIconDrop.

Change folder icons easily

This app can help you assign an icon to any folder on your computer without significant efforts. All you have to do is specify the target directory by either manually inputting the path in the designated field or using the ellipsis button and choosing a folder from your PC and selecting an icon file from your PC.
Note that only ICO files are supported by this application, so there's no way to set a BMP, JPG, GIF or any other image file as an icon, regardless of size. After you provide the app with the required data, you can define an icon index and choose between two index types before performing the operation.

Simplistic interface

FolderIconDrop's interface is plain, minimalistic and provides you with a series of functions that are easy to understand, which makes it an ideal tool even for novices who are looking for basic customization tools for their systems.
The main window consists of a bunch of fields, radio buttons, and a checkbox, all of which can be easily operated, as their functionality is pretty much self-explanatory. However, shall you need any clarifications, you can find a text document with brief explanations of this application's purpose in the root folder of the program.

Portable utility

Since it is portable, you don't need to install this tool on your computer, as simply extracting the archive file's contents and launching the executable lets you operate its entire array of controls.
You can also run it from removable storage media. It won't tamper with any of your Windows' registry entries, nor it will create any additional files or folders on your computer.

Handy icon changer for folders

In conclusion, FolderIconDrop is a lightweight, handy app that can help users change the default icon for any folder on their computer without significant efforts. It doesn't need to be installed and its interface is simple enough to be understood and operated even by novices.
