FAQ: How can I share an experiment with colleagues or back it up?
Experiment Builder projects can be packaged into a single EBZ file (File menu -> Package), which is easily transferred between computers or backed up. 
We recommend you do not share deployed projects between computers, but rather package up the project and unpack then deploy on the new Display PC. This will allow you to check that everything runs smoothly and will ensure compatibility with the new Display PC.

Note, if experiments are shared between colleagues please keep in mind that issues may arise when transferring between different operating systems. See If I program my Experiment in Windows, will it work with macOS or vice versa? for more details.
