What is an AIM file?

AIM files mostly belong to AOL Instant Messenger. AIM files serve more than one purpose.
Most of these files are AOL Instant Messenger log files that record chat histories in plain text.
Other AIM files are used in different contexts:
  • Anstoss Image File – stores image data, sometimes related to the MrSID format.
  • 3D Image File – holds 3D image information; see 3dMD for details.
  • Animation Information Model – an XML file that contains animation data used with 3D Studio Max; more info is available at Autodesk 3ds Max.
  • FilExt.com note: Examine the file content with a text editor to decide which type you have. Plain text without XML suggests a chat log, while XML elements or structured data point to one of the 3D or image designs.

    How do you open AIM files?
