Answer: Files which are given the.HQX extension are known as Macintosh BinHex 4.0 Encoded files, however other file types may also use this extension. If you are aware of any additional file formats that use the HQX extension, please let us know. ESoftTools EDB to PST Converter (1) - To recover the Corrupted EDB file database eSoftTools designed a tool known as EDB to PST Converter Software that effortlessly retrieves the lost database from an inaccessible EDB file and Extract the data like emails, contacts, chats, tasks, notes, journals, appointments, and other items to multiple file formats such as PST, EML, EMLX, MSG, and HTML.

Answer: Files which are given the.HQX extension are known as Macintosh BinHex 4.0 Encoded files, however other file types may also use this extension. If you are aware of any additional file formats that use the HQX extension, please let us know.

HQX files have been initially created for Apple Mac computers. The data inside the file has undergone compression as well as encoding, resulting in a 7-bit text instead of a 8-bit binary format. The encoding is done using the BinHex 4.0 encoding mechanism. These kinds of files are typically used for file transfer of binary files like documents, images or other multimedia attachments when sending an e-mail. They are used for different means of file transfer on the internet as well.

Technical details of HQX files

HQX files are text files that range from binary to hexadecimal. While BinHex 4.0 is used for encoding in HQX files, RLE is used for the compression. What makes HQX files predestined for file downloads on the internet or sending e-mail attachments is the fact that they couple combine both data and resource fork of the Mac file system to form only one archive. Files with the HQX extension are significantly bigger than the original binary files they were made out of. However, they are not as vulnerable to corruption during the transfer as the original binary files are.

Details

‘This utility converts Mac Bin Hex files (8-bit) to BinHex format (7-bit) and is similar to uuencode. BinHex is based on a UNIX program with the same name and function (http://www.natural-innovations.com/binhex/).

The original tool was a series of small programs (8to6, crc, etc.) piped together and run by a shell script. This is a completely rewrite as a C program (speeding it up considerably, needless to say), with an added run-length compression, and bullet-proofed (at least partly).

Source Code:
/* bin hex — bin hex aufs files
*
* if called binhex handles aufs files, if called unxbin handles
*.{rsrc,data,info} files
* will process multiple files
