The Extended File Allocation Table (ExFAT) file system is optimized to use with SSD (Solid State Drives). The ExFAT file system supports higher storage size compared to conventional File Allocation Table (FAT) file system. The Transaction safe Extended FAT file system (TexFAT) is a variant of ExFAT file system with power fail safe feature. The TexFAT file system is available in Windows CE (Compact Embedded) version 6.0 and higher version Operating Systems (OS). This paper adopts the reverse engineering methodology to explore cluster allocation algorithms of TexFAT file system by conducting various combinations of file system operations in Windows CE 6.0 OS. This paper also records the performance benchmarking TexFAT and ExFAT file systems.
