===Overview of NVFS===

The NVFS File System, as claimed by palmOne, is a file system designed to keep all information safe should the battery run out of power. Previous non-flash memory designs would lose all stored data in the event of a power loss. ''NVFS'' is a derivative of [[Flash Memory]], which continually stores all data even when no power is applied. palmOne invented NVFS in response to complaints that a handheld's data was destroyed when the battery power ran out. In the past, youit neededwas necessary to keep the handheld continuously charged to avoid losing data, since all information was stored in volatile memory.

A similar feature has been adopted by [[PDA|PDAs]] running the [[Windows Mobile]] 5.0 [[operating system]], and is named "Persistent Storage".
