Once you have chosen to use a file allocation table (FAT), exFAT, or exFAT with TFAT file system for a volume, you can implement FAT. After you have implemented FAT on a volume, your volume includes functionality of the type of FAT system you choose.
This procedure assumes you have an OS design that includes Storage Manager and a FAT file system.
To use FAT on a volume
In the Windows Embedded CE Control Panel, select Storage Manager.
In the FAT Utility dialog box, select the desired partition to format, or create a partition, if one is not available.
On the Properties menu, select Format.
To format a partition for FAT, set the FormatFATVersion registry setting.
You can set the FAT version to 12, 16, or 32.
To format a partition for TFAT, set the FormatTfat registry setting to 1.
If this value is set to 1, any unformatted volume is automatically formatted as a TFAT volume.
A FAT volume must have two file allocation volumes to be converted to TFAT. Operations in directories that have already been created using FAT may not be transaction-safe.
For Windows Embedded CE:
**To format a partition for exFAT, set the FormatExfat registry setting to 1.
- or -
Call FormatPartition.
If this value is set to 1, any unformatted volume is automatically formatted as an exFAT volume.**
