The ac file extension is related to a special text file that describes the geometry of a model used by AC3D.
AC3D files contain all available information about a model built with AC3D - textures, surface settings, materials, object data etc.
Many 3D modeling programs should be nowadays able to process AC3D geometry models.
It is likely that this file type can be exported to other 3D format.

The ac file extension is associated with the CaseWare Working Papers, an engagement software for Microsoft Windows operating system.
The ac file stores some kind fo client data from Working Papers.
You cannot open this file type manually, it is accessed by the program automatically.
Probably cannot be converted to anything else.

GLPK is a GNU package for solving linear programming and related mathematical optimization problems on Linux and Unix systems.
A GLPK .ac file, typically used as part of the package's build sources, contains Autoconf configuration definitions and macros. These definitions describe checks and settings needed to build the software.
Autoconf processes the file to generate a configure script. The resulting build files are then used to prepare GLPK for compilation; the .ac file is not a GLPK model or data file.
A GLPK .ac file is a plain-text source file. Open it with a text editor or source-code editor on Linux or Unix.
To use it in a GLPK source tree, run the appropriate Autoconf or Automake build tools rather than opening it in the GLPK solver itself.
This file is not normally converted to another file format. It is build-system source that is processed to generate a configure script and other build files.
If the build definitions need to be changed, edit the text and regenerate the build files with the Autoconf or Automake tools as required.
