The file system allocates a number of blocks that together provide enough space to hold the file data. Unless the file fits exactly into the aggregated blocks, then some storage space allocated to the file is unused by the file. A file's allocated storage size is sometimes referred to as file size or alternatively with qualification such as ...

Even when Storage Spaces is not thinly provisioned, ReFS may still be unable to dependably correct all file errors in some situations, because Storage Spaces operates on blocks and not files, and therefore some files may potentially lack necessary blocks or recovery data if part of the storage space is not working correctly.
The byte, 8 bits, 2 nibbles, is possibly the most commonly known and used base unit to describe data size. The word is a size that varies by and has a special importance for a particular hardware context. On modern hardware, a word is typically 2, 4 or 8 bytes, but the size varies dramatically on older hardware.
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix mega is a multiplier of 1 000 000 (10 6) in the International System of Units (SI). [1] Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of ...

The Working Set Size (WSS) is the size of this data set. The significance of this is that if the Working Set Size is larger than the available memory in a virtual memory system then the memory manager must refer to the next level in the memory hierarchy (usually hard disk ) to perform a swap operation swapping some memory contents from RAM to ...
