'''Non-Volatile File System''' ('''NVFS''') is a [[Flash memory#Flash file systems|flash memory file system]] introduced in the release of [[Palm, Inc.|Palm's]] [[Personal Digital Assistant]] handheld models [[Tungsten T5]], [[Tungsten E2]], [[TX (handheld)|Palm TX]], [[Z22 (handheld)|Z22]], [[Treo 650]]/[[Treo 700p|700]]/[[Treo 680|680]]/[[Treo 755p|755p]], and [[Palm Centro]].

NVFS was developed to retain all data even if the battery runs out of power, a significant improvement from previous designs that lost all stored data upon power loss. The system uses NAND flash memory technology, which consumes less power and makes charging less frequent. However, due to NVFS's architecture, using clusters of 512-byte blocks, some power users have complained that files take up around 33% more space than in volatile file systems. palmOne addressed this by offering a free 128MB SD Card and committing to reduce NVFS overhead through updates. A notable update improved memory management efficiency by reducing the block size from 512 bytes to 16-32 bytes.
