[edit] LRX

If the files are protected by DRM the extension is changed to LRX. Note that the LRX file for the Sony Librie is not compatible with the DRM file used on the Sony Portable Reader Devices. Products purchased on the Sony Connect store will typically have this extension. The Sony DRM method provides for up to 6 devices that can work off the same owner code. One of those codes is used by the PC Desktop Reader called the "eBook Library."
