What is an AOF File?

How to Open, Edit, & Convert AOF Files

A file with the AOF file extension is an Artlantis Object file. These files are 3D images that the Artlantis Studio and Artlantis Render software use as part of an Artlantis 3D Scene (.ATL file).

Newer versions of the Artlantis software have replaced the Artlantis Object file format with files that have the .ATLO file extension.

If your AOF file isn't used with Artlantis software, it may instead be an Acorn Object Format file.

These files are combined with object libraries on the now discontinued Panos operating system (developed by Acorn Computers) to produce an executable program image file (.RIF).

Your AOF file may be an append-only file if it's not in either of the above formats.

How To Open an AOF File

AOF files that are Artlantis Object files can be opened with Artlantis Studio or Artlantis Render. Demo versions are available for both programs through that link on the download page.

While your AOF file is most likely in that format, it's possible that it's instead an Acorn Object Format file. These files can be opened using Acorn 32000 Linker, but I can't find a download link There may not be one available anywhere since the Panos OS isn't widely used.

Append-only files using the AOF file extension are associated with Redis, so you might be able to open one with that program.

Note: Don't confuse other, more common file types with AOF.

For example, AFI, AOB (DVD Audio), AIFF/AIF, and ALO files look a bit like AOF files but they all open with different programs.

Tip: If your AOF file is most definitely not used with Artlantis software, but you aren't sure how to open it, try using the Notepad++ text editor to open it. When you view the file as a text document, you may be able to pull out some information within the AOF file that explains the format it's saved in.

If you find that an application on your PC does try to open the AOF file but it's the wrong application or if you would rather have another installed program open AOF files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an AOF File

Artlantis' Media Converter program is used to convert AOF to ATLO. If you download Artlantis Studio, which comes in a ZIP file, there are two EXE files that you can choose from. One is Artlantis Studio and the other is Media Converter.

Artlantis has some plugins available for programs like Sketchup and Revit that let you export models to the ATL format. Those files, when opened in Artlantis Studio, can then be exported to the new Artlantis Object file format (.ATLO).

Again, I don't have a download link for Acorn 32000 Linker, but if you do happen to have that program running on the Panos operating system, I know that you can use it to open the AOF file.
