# Objects

Objects are primarily created by the identifier from Paths. They can be created from any kind of file or directory. All metadata created around files in Spacedrive are directly attached to the Object for that file. 

A CAS id is generated from samples of the byte data, which is used to associate Objects uniquely with logical Paths found in a location.

Some Objects are purely virtual, meaning they have no Path and are likely only used in a Space.
