What is an APM file?
Metafile image created by many Windows programs originally designed to scale images on output devices; contains an image and metafile header information; similar to .WMF file except that it contains a preceding 22-byte header.
APM files cannot be used natively by the Windows API metafile functions GetMetaFile(), CopyMetaFile(), and PlayMetaFile(). They must first be stripped of their 22-byte header, which can be completed with the Microsoft program Wmapmf.exe.
