The ACT File Extension
Audio Files: ADPCM Audio File
File extensions tell Windows which programs are used to open different types of files. Common file extensions include .txt, .doc, .jpeg, etc. Windows stores information about each file extension (including File Extension ACT) in the Windows Registry.
If you receive errors when trying to open ACT files, it could be for the following reasons:
Missing Host Application: Windows doesn't have a default application that is capable of opening, reading and rendering information embedded using the ACT file specification.
Corrupt File Type Association: The default host application may exist for ACT file type but its file association with ACT files was corrupted in Windows Registry.
We recommend that you download and install PC Health Advisor to fix both types of issues:
Identify and install Host Application: PC Health Advisor scans your PC, identifies the missing host application for ACT files, and provides you with the most up-to-date copy of the host application.
Repair File Type Association: PC Health Advisor repairs corrupt file type associations so that ACT files can always be opened and viewed correctly afterwards.
