To create Live devices that you can give to other people, you'll need to ensure the device is packaged with all the files it needs. We call this freezing a device. (Don't confuse this sense of freezing with other uses of the term in both Max - frozen attributes - and Live - frozen tracks.)

Basic freezing is explained here. If your device opens files during its operation (such as a folder of samples or images), you may need to add these files as dependencies before freezing.

Once you freeze a device, it cannot be edited. You'll need to unfreeze it first.

If you open a frozen device for editing and see this icon in the patcher toolbar

you'll need to resolve any conflicts between the files in the frozen device and those you have on disk before you can unfreeze.
