'size' and 'size on disk'??

[gopi_vbboy]

->what is difference between 'size' and 'size on disk' properties on file properties in windows explorer

[dd_wingrider]

The space allocated to files is determined by the cluster size for the formatted partition. Cluster size is higly variable in FAT32/FAT16 file systms, but Windows 2K/XP using NTFS has clusters of 4096 bytes.

To compute the real space allocated to files you need: (FileSize/4096) rounded to the next higher integer x 4096, e.g.
FileSize 37352 bytes
FileSize/4096 = 9.11 rounded to 10

Space Allocated 40960 bytes (4096 x 10)

If the file is then compressed the real space allocation may be lower then native FileSize.

+1 to dd_wingrider i agree the explaination...

So i learnt that 'size on disk' for NTFS less than 'size',more than 'size' in case of FAT32. what is cluster size per byte in FAT32.

Default cluster size for FAT, FAT16, FAT32 and NTFS : http://support.microsoft.com/kb/140365
