On a fairly standard WinXP Pro 32 bit computer, what is the smallest amount a disk space actually used by a file saved to the disk.
For example, does a really small file that may be only 10 bytes in size actually take up only 10 bytes of space on the disk, or a larger amount?
Thanx

When a NTFS volume is initialized (formatted) the user has a chance to specify the "Allocation Unit".

This is the minimum file size.

By default on most systems it is 4K bytes.
