Owned by Toshiba Corporation, lbrtfdc.sys is the system file for Libretto Floppy Drive Controller, a line of second-level notebook computers produced and designed by Toshiba to be distinguished as combined functionalities in a small device size like a hardback book. Lbrtfdc.sys is designed by Toshiba Corporation exclusively for Microsoft Corporation for its Windows-based computers. The Libretto technology is the line of subnotebooks customized by Toshiba to combine functionality and small size, a full Windows PC squeezed into a device no bigger than a pocketbook. Different models of Libretto originally used 486 processors from AMD or Advanced Micro Devices, and were initially available in Japan only. Later, in the release of the Libretto 50, Toshiba used the Pentium MMX and Intel Pentium processors. Much recently, when the L series of Libretto was introduced in 2001, Toshiba moved to a new processor, the Transmeta Crusoe, with the model U100 released in 2005 returns to the Intel Pentium processor.
