Open KMS File

KMS files are a type of file primarily associated with Microsoft Windows, more specifically with Key Management Services (KMS) for Windows Server. These files are used to aid in the activation of Microsoft Windows and Microsoft Office copies deployed in bulk across a corporate network, allowing activation in large quantities. However, there are some other software that also use the KMS file extensions, which we'll describe separately in the following sections.

KMS file in Microsoft Key Management Services

The Key Management Services (KMS) from Microsoft is a server technology that allows businesses and enterprises to centrally manage the activation of Microsoft products, thus easing the process of product activation for large organizations. This means the KMS file extension can be related to license and activation data of the Windows Server. However, it's not a common file type or format that could be open or used in a regular way. These files are mainly accessed and managed through the specific administration tools and services provided by Microsoft.

KMS file in Correlate

Another software that uses the KMS extension is Correlate. Correlate's KMS files are Knowledge Management Save files, which hold references to numerous pieces of information saved in a single Correlate disk file. In this case, KMS files can be opened by the Correlate software, a knowledge management tool that allows you to create a database of information and assets.

KMS file in PlanetPress Design

Next is the PlanetPress Design which uses KMS file extension for its Keyman Developer Keyman Source File. It's connected with scripts written in the Keyman language. The Keyman is a programming language developed to create and modify keyboard layouts. In this case, the KMS file can be opened and modified by using Keyman Developer, a part of the PlanetPress Design suite of applications.

KMS File Important Information

Finally, if you encounter a file with a KMS extension but can't open it, it can be due to two main reasons. Either you don't have the relevant software installed on your device, or the file is not associated correctly with the software meant to open it. In certain scenarios, lack of sufficient computer hardware resources can also hinder file opening. Security problems can also occur if the KMS file has not been obtained from a trusted source. Therefore, always be sure of the source of your files before attempting to open them.

Also, it's important to remember that KMS files, in particular, those relating to Microsoft Key Management Services, should not be tampered with unless you understand thoroughly what you are doing as they are closely related to system licensing. Incorrect handling may cause serious problems or even completely disable your system.

Keep these points in mind as you handle KMS files, and they should be no problem for you.
