File System Specification
The terminal provides file systems on different hardware devices. Instead of using the common
alphabet notation for file system devices (‘A:’, ‘C:’), the Genus terminal identifies the file storage
devices as:
Storage Device
Memory size
Location
‘\flashdisk’
40 Mbytes
Seldom write, frequent read.
Used for firmware, user
applications, and application data.
‘\ramdisk’
2 Mbytes
High read/write usage. Data is
preserved through power loss.
Often used for transaction
(punch) storage.
‘\scratchdisk’
5 Mbytes
High read/write usage.
Temporary file storage. Not
preserved through power outage.
The Genus Terminal uses the ‘\ramdisk’ location to store transactions. This location has
approximately 1MB of storage available for transactions (punches). Refer to the reference section for
Calculating Number of Transactions That Can Be Stored.
