What is an ACU file

ACU files mostly belong to AcuCobol-GT. ACU files are used by several applications and are not a single universal format. They can serve different roles depending on the program that created them.
For example, one common use is as an Application Configuration Utility file. This type is used in environments like AcuCobol systems (managed by SF1 and AcuCobol-GT) to store configuration settings or index data for COBOL-based applications.
Other uses include:

AutoChart Sonar Data: Files that store sonar and chart data for analysis by Autochart PC.

Chilean Financial Report: Files formatted for financial reporting and viewed with ACU Report Viewer.

FilExt.com tip: Each variant uses the same extension but has a different internal structure. It is important to use the original software for opening and editing these files to avoid data corruption.

How to open ACU files

You need a suitable software like AcuCobol-GT to open an ACU file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ACU file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ACU file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert ACU files:

AcuCobol-GT
See the previous paragraphs to learn more about the main application. ACU files are often referred to as AcuCobol-GT settings because this type of file is primarily created or used by this software.
ACUCOBOL-GT (Intermediate Object File) by Acucorp, Inc.
Acucorp offers an open systems COBOL, ACUCOBOL-GT, that lets you write a program once, and run it on virtually any operating system platform without recompiling. This is achieved using a pseudocode system. Rather than producing native code for a single platform, our compiler produces a small, independent object that can be placed on any open-systems machine. At runtime, the object is executed by a native runtime executable. The Mime types used with this association are: application/vnd.acucobol. The identifying characters used for this association are - Header magic number: 0x10121420.

How to solve problems with ACU files

Associate the ACU file extension with the correct application.
Update your software that should actually open settings files. Because only the current version supports the latest ACU file format. Search, therefore, e.g. on the manufacturer website after an available AcuCobol-GT update.
To make sure that your ACU file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
