Do 
        stat Standalone1.avi
or, if you are using GNU/Linux - 
        strace -v -e lstat64 stat Standalone1.avi

Multiply the "Blocks:" figure by 512 (in the case of the stat output,
this is st_blocks).  If the result is less than the file size, the
file is a sparse file.  An alternative is to compare the first and
second sizes given by

        ls --block-size=1 -ls Standalone1.avi
