The alignment factor determines where segments in the .EXE or .DLL file start. From the beginning of the file, the start of each segment is aligned at a multiple (in bytes) of the alignment factor. The alignment factor must be a power of 2, from 512 to 64K.

Default: /ALIGNFILE:512

Abbreviation: /A
