<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">On a disk archive, this indicates the size needed to store the file.&nbsp; Some files take less space than you might expect because they are "sparse".&nbsp; On filesystems that support sparse files (ProDOS, and to some extent DOS 3.3), a block filled entirely with zeros isn't actually stored on the disk.&nbsp; Instead, the file system structure is updated to indicate that there is a gap, and when the file is read the missing data is filled in with zero bytes.</FONT></P>
