Have you encountered a problem with a OTP file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a OTP file here. In the further part of this page we have added a list of programs that should open your OTP file. It is enough you choose a proper application for your operating system, download and install it.


The file extension OTP identifies the templates for the presentations of the OpenSource application OpenOffice.Org Impress.

An OTP file contains formatting information, fonts, colors, but can also contain text and images. Otp files can also contain macros. These macros may contain malicious code, which is why you should do a virus scan before running it.

The OTP format is part of the Open Document for Office Application Standard, also known as OpenDocument. Originally developed by Sun Microsystems and based on XML, the standard has been defined and developed by the Organization for the Advancement of Structured Information Standards (OASIS).

OpenDocument is the native format of OpenOffice.Org Suite. Otp is a standard version of the presentation software OpenOffice.Org Impress.

How to open a OTP file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the OTP file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a OTP file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support OTP files. At this point we are looking for disk space where the application was installed in and we can link it with a OTP file. Since then, our operating system will use the selected program to support all OTP files.

Other issues

Despite the described problem with OTP there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the OTP file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the OTP file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
