The block size on my filesystem is showing 256KB when tune2fs shows 4KB

The block size on my filesystem is showing 256KB when I look at a file though explorer .. how do I make this smaller ?

When I look at a BATCH file from explorer and look at the properties I see
Size 63 byte (63 byte)
Size on disk 256KB (262,144 bytes)

I would like something close to 4KB.

I have lost 3gb of disk space just putting my pictures on this filesystem.


I have run tune2fs to look at the filesystem and it shows the block size being 4KB. So why does explorer think its 256KB.

Do you mean you are looking at the file with Windows explorer? If so, t is because Windows doesn't understand ext3 file systems or logical volumes.

Yes I am using Windows Explorer to look at the folder. I also used TREESIZE pro to show me the 3gb of wasted disk space after copying over 18g of picutures.


I am planning on using my Thecus 5200Pro as a backup for my QNAP TS-509Pro box. (RSYNC job kicked off by the 5200Pro being woken up weekly). I got the RSYNC working that how I copied over the 18g of pictures as a test run.

On the QNAP box I see the block size being 1KB using Windows Explorer.
