I am new to sparse files and wondering if compression zones and sparse ranges are the same thing.
I recently learned the term compression units from here: http://www.flexhex.com/docs/articles/sparse-files.phtml
When it comes to a compressed or a sparse file, NTFS divides the file into chunks called compression units.
However in this example they have sparse ranges: https://code.msdn.microsoft.com/windowsdesktop/CSSparseFile-6e26dc97
SetSparseRange...The minimum sparse size is 64KB.
From reading elsewhere I see that NTFS disk clusters are 4kb in size and windows defines a compression unit as a collection of 16 units each 4kb... 16 * 4 == 64kb so are they the same?
I can how in Microsoft NT world they have a different term (compression units) than others (sparse ranges) but I'm not sure if I have this correct.
I am having a tough time finding thorough documentation so if you know of any resources I will gladly look into them.
TIA
