What is a hdz file and how do I open a hdz file?
A compressed Poser hand pose file can be created using the Poser application. These compressed Poser hand pose files are classified as 3D image files and are stored in the HDZ format, which is implemented with compression specifications and encoding standards proprietary to Smith Micro, developer of the Poser program. This software was primarily developed to use these HDZ files in displaying the hand poses of animated characters created using the Poser application. This program is generally classified as a 3D character development and animation modeling application, and the content of these compressed HDZ files may include finger positions and hand gestures of animated characters developed using the Poser software. Particular HDZ files are associated to corresponding animated Poser characters. This means when a user views an animated character, the Poser application locates the HDZ file that correspond to the hand gestures and finger positions integrated into the animated character.
