What is chasControlFFSFileSize?

This object reports the size, in bytes, of a specific file stored in the chassis's flash file system. An admin checking whether there's enough free flash space, chasControlFreeFFS, for a new firmware upload uses this to identify which existing files are large enough to be worth deleting to free up room. Finding an old firmware image reporting a size of 3,145,728 bytes (3MB) tells the admin exactly how much space deleting it would reclaim.
