Hi Everyone,
I'm having this issue and spend huge amount of time to search around but cannot explain why FSRM reports a big diffeent on used space compare to Windows Folder Properties.
As you can see following, Windows reports 513 GB but FSRM says662 GB
Based on my research, the difference is due to Windows block size and small file. Yes, we have around 150.000 small files 2KB, 10KB,20KB, etc. Our default block size on disk is 4KB.
Let say average each small files waste 2KB, the waste space on disk is 150.000 x2KB=300 MB only.
Where is approx 150 GB difference here?
How can we explain this. Can someone please help? Thanks
ps: I'm using Windows 2008R2, 4KB block as mentioned. No compression.
