A .DTP file is a Publish-iT Document. This is an older file format created with Serif publishing software. The Publish-iT Document format was used in early 2000s for creating presentations and newsletters. It contained complete documents including text, images, and layout information in one file. Today, the one-file approach has changed to many files for content, design, and export. The files are now used for archiving purposes as most modern programs such as Microsoft Word and Adobe InDesign cannot open the.DTP file format.
File Extension Details
The.DTP file is a standard binary file type associated with the Publish-iT program created by Serif. The complete content of a Publish-iT project, including text, images, and layout information is stored in this file. To open this file type you need a compatible version of the Serif program or another program that can read binary files such as Notepad++. It has no associated MIME type and its extension is not related to other publishing file types like .PSD, .AI and .INDD.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .DTP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .DTP extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .DTP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .DTP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .DTP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .DTP file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .DTP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .DTP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .DTP file) will be extended to the maximum.
It is also good to check
- if the .DTP file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
