What is the .DT_ File Extension?

.DT_ File Extension Description:

The DT_ file extension is used for the DAT Backup system used for backing up files.

The files with the .dt_ file extension typically contain backup data files that serve as protection against data loss. As part of the DAT backup system, these files contain preventive tools used by PC users for storing data files. The creation of files with the .dt_ file extension can be optionally set to automatic; to be performed during scheduled backup process. Data files are stored as files with the .dt_ file extension to identify them as backup files. Just like DAT files, files with the .dt_ file extension can be opened in Microsoft Word and Notepad.

Files with the .dt_ file extension can be stored in a folder designated by the user. It is usually placed in a location that will not be affected in case of system crash, such as external drives. If the .dt_ file extension is placed in a separate physical drive, it will then be preserved in case an eventual failure of hard drive happens.

The DT_ file extension is also known to identify Macintosh File Data Forks. Macintosh has designed a data fork as a file's data container. It is composed of a series of consecutive bytes of data. Macintosh files taken as a sequence of bytes that comprise an application usually contain a resource fork and a data fork. The file with the .dt_ file extension is thus an essential component in Macintosh operating systems and applications.

Files with the .dt_ file extension simply contain the data of a file. In storing the DT_ file extension, the location (whether in the data fork or the resource fork) depends on the files structure or if it is built as a resource or not. Data can be located in a resource fork if a document only contains data. On the other hand, a document or application can contain both data and resource, and are thus located both in the data fork and resource fork. The DT_ file extension is hence not limited in the data fork.

The use of files with the .dt_ file extension in Macintosh operating systems and applications are easily seen when retrieving backup data. Important program files and even executable codes used by an application can be contained in the files with the .dt_ file extension. In document files, the DT_ file extension is implemented when storing windows locations, fonts, icons and other user preferences that are unique to a particular document.
