Backup file created by form•Z, a 3D solids and surfaces modeling application; stores a backup of a form•Z .FMZ project file; used for archival purposes and for restoring the project from backup.

NOTE: Form•Z also creates auto-save files with the .FZA extension that can be used for restoring a project if a backup file is older than the last auto-save.

Bin file used by Fritzing, a program that allows users to create interactive electronics designs; stores information about electronic parts (.FZP files), which can be any part of an electronics circuit; includes the part name, module ID, the .PNG icon for the part, and geometric coordinates.

The bins and parts stored in each bin are displayed in the "Parts" pane on the right side of the Fritzing interface. The parts can be dragged from a bin and paced onto a sketch. You can also add parts to your own custom bins and load them into Fritzing.
