Title: File sizes
Post by: derek on October 05, 2001, 06:27:28 PM

Having installed and configured e-smith 4.1 as a local server only I copied a numner of files from Win2K Pro to a shared directory. When I right-clicked (in Win2K) on a file to see its properties the info displayed was:

File Size: 80MB
File Size on disk 650MB

I am showing approximate values. Actual rspective numbers were slightly different. The point, however, is that the difference between reported File Size and File Size on disk were pretty shocking to me. I intended on using e-smith solely as a file server for my home network.

Does anybody know about the problem? Is it really a problem? Or perhaps Win2K somehow erred due to the difference in partition types between Win2K and Linux?

In case it matters, relevant specs of my system:
P150
64RAM - EDO
two WD HDDs 40GB each, ata100
note: the BIOS doesn't auto-recognize the discs but when set manually the system boots and reports proper disk sizes.

Any comments will be appreciated.

Windows believes the file size is based on clusters of 512 KB (524,288 bytes) each. Just so it can understand the whole disk...

Case in point:-
AGSatellite running on server creates file ddatabase.dat of 79872bytes

ls -altF ddatabase.dat -> 79872bytes
du ddatabase.dat -> 84Kbytes
i-bay, right click, properties, size on disk -> 512 KB (524,288 bytes)

It takes up whatever is du (disk usage) tell you it does.
