- * DESCRIPTION:
- * Plasma File System. Supports RAM, flash, and disk file systems.
- * Possible call tree:
- * OS_fclose()
- * FileFindRecursive() //find the existing file
- * FileOpen() //open root file system
- * FileFind() //find the next level of directory
- * OS_fread() //read the directory file
- * BlockRead() //read blocks of directory
- * MediaBlockRead() //low level read
- * FileOpen() //open next directory
- * OS_fwrite() //write file entry into directory
- * BlockRead() //flush changes to directory
