# -filealign (C# Compiler Options)

The -filealign option lets you specify the size of sections in your output file.

## Syntax

-filealign:number


## Arguments

number
A value that specifies the size of sections in the output file. Valid values are 512, 1024, 2048, 4096, and 8192. These values are in bytes.

## Remarks

Each section will be aligned on a boundary that is a multiple of the -filealign value. There is no fixed default. If -filealign is not specified, the common language runtime picks a default at compile time.

By specifying the section size, you affect the size of the output file. Modifying section size may be useful for programs that will run on smaller devices.
