What is a .DET file?
The file extension .DET is associated with Sage ACT! 5, which is a software program designed for managing contact information. This file type is specifically used to store email messages created or used within the ACT! program. The .DET file format is a proprietary format, meaning it is unique to the ACT! software and not commonly supported by other email or contact management programs.
A .DET file contains the content of a single email message, but it does not include any file attachments that might have been part of the original email. This means if the email had any documents, images, or other types of files attached, these would not be saved within the .DET file.
To open a .DET file, you would typically use the Swiftpage Act! software, which is the updated name for the Sage ACT! program. This software allows users to view, manage, and organize their contacts as well as the emails associated with them. If you do not have Swiftpage Act! installed, you may have difficulty opening a .DET file because it is not supported by most other email or contact management programs.
