| Notice that, if the peer is enabled, we will not have a disabled file. |
| <p/> |
| And for other files, to avoid depending on atomic rename, we will use two files for storing the |
| content. When loading, we will try to read both the files and load the newer one. And when |
| writing, we will write to the older file.</div> |
