Allocated Altitudes

A file system minifilter driver developed to the Filter Manager model must have a unique identifier called an altitude that defines its position relative to other minifilters present in the file system stack. Minifilter altitudes are allocated by Microsoft based on minifilter requirements and load order group.

The current altitude allocations are listed for each of the following load order groups.
