File TypeBinHex 4.0 Encoded File
What is an HQX file?
An HQX file is a binary to hexadecimal text file created for Mac computers. It contains data that has been compressed and encoded from an 8-bit binary format into a 7-bit text format. HQX files can be useful for transferring binary images, documents, and multimedia as text in email attachments.
HQX files help to maintain file integrity for Internet downloads, email attachments, and other file transfers since they combine the data fork and resource fork from the Mac HFS structure into a single archive.
BinHex 4.0 files take up more disk space than their original binary file. They always begin with the line "(This file must be converted with Binhex 4.0)."
