This is the flash disk (fd.) object, it allows you to use your device's flash memory for data storage. There are two methods of working with the flash memory:
| • | With direct sector access, you can write and read flash sectors directly, without burdening yourself with the file system. |
Both methods can be used concurrently and complement each other whenever necessary.
Here is what the fd. object has to offer in terms of the file-based access:
| • | Ability to store up to 64 files located in a single root directory (subdirectories are not supported, but can be emulated). |
| • | Ability to open and work with several files at once. |
| • | Fast and flexible search to locate data within files. This also includes a record-style search! |
| • | Transactions to ensure disk integrity in the toughest of conditions (power failures, etc). |
| • | A method for firmware/application self-upgrades (not supported by all platforms). |
