# Properties of SF

Following the data compacting and encrypting process, Enerzion distributes encrypted data fragments—known as Splitted Files (SF)—to a number of other users (downloaders). These users receive the data files under the following conditions:

* They cannot access the original, unencrypted file.
* They cannot decrypt the files.
* Each file is unique and identified by a specific code and a separate NFT.
* The files are free from any malicious code.
