File extension apm is used for Microsoft Windows metafile image format, also known as Aldus Placeable metafile. Many Windows-based applications import or export Windows metafiles in a format known as the Aldus Placeable Metafile (APM) format. In this format, these metafiles cannot be used with the Windows metafile functions such as GetMetaFile(), CopyMetaFile(), PlayMetaFile(), and so on. To use these metafiles, the APM header must be removed from the metafile and the remaining metafile bits must be written to a newly created metafile.

Microsoft Windows Metafile Format (WMF) files are used to store both vector and bitmap-format graphical data in memory or in disk files. The vector data stored in WMF files is described as Microsoft Windows Graphics Device Interface (GDI) commands. In the Window environment these commands are interpreted and played back on an output device using the Windows API PlayMetaFile() function. Bitmap data stored in a WMF file may be stored in the form of a Microsoft Device Dependent Bitmap (DDB), or Device Independent Bitmap (DIB).
