<section id="GUID-4967E92B-71BD-5646-855B-94C2570E22EE"><title>Introduction</title> <p>The

FAT32 file system is an update of the industry standard FAT file system. </p> <p>The

Symbian platform FAT32 file system implementation supports the FAT12, FAT16

and FAT32 file systems types. </p> </section>

<section id="GUID-572319F8-71AA-4CDB-A21B-D8A13BD822A7"><title>Background information</title> <p>The following are features

of the FAT32 file system: </p> <p>It is used for storing user-data on NAND

Flash, internal RAM drives and removable media e.g. SD cards, MMC cards. </p> </section>

<section id="GUID-27EFD322-FC12-4FFD-867D-0EA7F70F583F"><title>FAT32 features</title> <p>FAT32 provides the following features: </p> <ul>

<li id="GUID-6949B548-0B68-542F-8D37-C703D6F29F44"><p>Can handle much larger

drives than is possible with the FAT file system. </p> </li>

<li id="GUID-D6BD828B-491E-5BAD-8451-17AA0F31FF3B"><p>There is a maximum upper

limit for the size of a drive. </p> </li>

<li id="GUID-1C6D8C38-8D26-570E-853E-8AC8B2194975"><p>When files are deleted

and written to the media, then files can become scattered over the media (fragmentation)

leading to slower access times. This can be addressed by executing a defragmentation

utility, however this is a time consuming process and on some media, e.g.

memory cards, this process cannot be undertaken. </p> </li>
