If you received a file from a newer version of Fritzing, it might have been incorrectly renamed. Try changing the file extension from .fz to .fzz and opening it in Fritzing. Conversely, if you have an .fzz file, you can change the extension to .zip , extract it, and find the internal .fz file inside. File Corruption

If your (Fritzing) fails to open a file, consider the following steps:
The file is actually an file (a Fritzing Part file), which requires importing into the Fritzing parts library rather than opening as a standalone project. This link or copies made by others cannot be deleted
