Explorer Extension is a free Windows software that offers a subset of the decoding features of Directory Toolkit. It enables users to decode internet email messages and attachments stored in files.

The extension enables you to decode several attachment types, including Base64(MIME), UUENCODED, XXENCODED, BinHex (Mac format), XXENCODED, printed-quoteable, User (table), and plain text encoding. You can do this by simply right-clicking on the file in Windows Explorer and selecting the "Decode" option from the menu.
The fact that the extension is a freeware makes it a great option for users who don't want to spend on expensive decoding software. However, at the same time, it offers a limited range of features compared to the directory toolkit. Still, for casual users who don't require advanced features, this extension is more than sufficient.
Overall, the software efficiently completes its intended function – decoding files in a convenient and straightforward manner, and that too, without costing you even a dime.
