Access: read-only

Description: Free space within a Flash partition. Note that the actual size of a file in Flash includes a small overhead that represents the file system's file header. Certain file systems may also have a partition or device header overhead to be considered when computing the free space. Free space will be computed as total partition size less size of all existing files (valid/invalid/deleted files and including file header of each file), less size of any partition header, less size of header of next file to be copied in. In short, this object will give the size of the largest file that can be copied in. The management entity will not be expected to know or use any overheads such as file and partition header lengths, since such overheads may vary from file system to file system. Deleted files in Flash do not free up space. A partition may have to be erased in order to reclaim the space occupied by files.

This object is a 64-bit version of ciscoFlashPartitionFreeSpace

What is ciscoFlashPartitionFreeSpaceExtended?

Reports the amount of free space remaining in a flash partition as a 64-bit value, accounting for file, partition, and device header overhead.
