You're here because you have a file that has a file extension ending in .hqx. Files with the file extension .hqx can only be launched by certain applications. It's possible that .hqx files are data files rather than documents or media, which means they're not meant to be viewed at all.

A BinHex 4.0 encoded file is implemented with encoding specifications that can transform binary data into its Hexadecimal text version. This is done to improve the stability of these binary files for distribution purposes. A BinHex 4.0 encoded file is saved in the HQX format and is affixed with the .hqx extension. These BinHex 4.0 encoded files and the HQX file format along with the encoding specifications integrated into this file format were initially developed for Mac platforms. The content of a BinHex 4.0 encoded file consists of 7-bit data in text format, and this is from the 8-bit binary data stored in the file before it was encoded as a BinHex 4.0 encoded file. The size of a BinHex 4.0 encoded file is larger than the size of the binary data before it was encoded. This is because Mac's structural resource and data forks are implemented into a BinHex 4.0 encoded file. Binary data that can be encoded in the HQX format and converted into an .hqx file includes digital multimedia content like videos and images, along with document presentations embedded with digital objects and visual elements. The Corel WinZip 16 Pro software can be used in computers running on Microsoft Windows-based systems to implement support into the computer for creating, opening and accessing the content of these HQX files.

Launch a .hqx file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .hqx file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .hqx files aren't yet associated with it. In this case, when you try to open a .hqx file, you can tell Windows which application is the correct one for that file. From then on, opening a  .hqx file will open the correct application.

Be careful not to rename the extension on .hqx files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .hqx. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
