Option
/A[[LIGNMENT]]:size
The /ALIGN option aligns segments in a segmented executable file at the boundaries specified by size. The size argument must be an integer power of two. For example,
/ALIGN:16
indicates an alignment boundary of 16 bytes. The default alignment is 512 bytes.
This option reduces the size of the disk file by reducing the size of gaps between segments. It has no effect on the size of the file when loaded in memory.
