in May 2008, enabled Ogg Vorbis compatibility for the Sansa Clip. The 01.01.30 firmware update improved OGG support and added FLAC support. The latest firmware packages for the Sansa Clip are 01.01.35 and 02.01.35, which depend on the hardware revision. The device (firmware 01.32+) has five folders: Audible (for Audible.com), Audiobooks (for files that you decide are audiobooks, allows for "bookmarking" of every file in this directory by a resume playback feature), Music, Podcasts (also allows every file in this directory to be resumed at a later time), Record (for recordings done on the device, these are in WAV file format). Sansa Shaker The Sansa Shaker released in 2007 is a screenless digital audio player and comes in colors of blue, red, white, and pink with an SD card slot. One 512 MB or 1 GB card is included, and cards up to 4 GB (non-SDHC) can be used. The tubular design is intended to be kid-friendly, and the player resembles a saltshaker, as it will randomly skip one, two or three songs when shaken. The Shaker plays up to 10 hours of continuous audio with a AAA battery, and has twin headphone jacks and a built-in speaker. The upper controller band adjusts volume and the lower controller band skips to next/previous song or fast forwards/rewinds the current song when held. Unlike other players, the only supported audio file format is MP3. When the memory card is removed during playback, the player emits an "uh-oh" sound. When the player's memory card is put back in, it emits a popping sound. Sansa Express The Sansa Express is a flash-based digital audio player in capacities of 1 GB and 2 GB. It has a built-in USB connector and a 1.1-inch, duochromatic OLED display, a microSD slot, an FM tuner, a microphone for voice recording, an internal Lithium-Ion battery, and a lanyard to wear it around the neck. It is also able to record FM radio and voice on its internal memory. This player is not considered as a descendant of the c200 series, as it only plays audio. It is more similar to the m200 series and maintains much of its design and internal software structure. It is the world's first known cable-less flash-based digital audio player, though a USB cable is included in the package if one is required to be used. c200 series The Sansa c200 has a removable, lithium-ion
