What is an AC_ file

AC_ files mostly belong to CaseWare Working Papers. The AC_ files are CaseWare documents that use the Microsoft Compound File format to store accounting work papers and related financial data.
These files are structured to hold several embedded streams, which may include text, calculations, and metadata used in audits.

They are created and managed with CaseWare Working Papers software.

The design allows a single file to keep multiple pieces of data together in a controlled environment.

The format is specialized for accounting and audit purposes, ensuring that the data integrity is maintained.
