File Extension HQX

File type: BinHex Encoded File

About the HQX file type:

If Windows cannot find the appropriate program associated with .HQX files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The .HQX file extension identifies Macintosh binary files encoded into ASCII files and which contain only printable characters. This is useful when transferring files between different platforms since all systems can handle ASCII files and so helps to avoid corruption of the file.

Additional Information:
You can use BinHex files with many e-mail programs (as long as they include a BinHex encoder and decoder) for sending and receiving attachments. Sample encoders and decoders include Allume Systems Stuffit Expander and WinZip.
