.KEY File Extension

LightWave 3D is a computer graphics application that renders static and animated 3D images. Professionals use the software in various fields, including television, film, video game development, building visualizations, and product design.

You will only encounter a software registration KEY file when purchasing and activating LightWave 3D (before version 11). For example, after purchasing LightWave 3D online, NewTek displays instructions to download LightWave 3D and provides a license.key file to register the application to your computer.

However, since NewTek replaced KEY files with LWK files, LightWave 3D now uses LWK files. Therefore, to register the trial version of LightWave 3D (11.0.3 or later), place the LICENSE.LWK file in the "licenses" folder in the LightWave installation directory to register the software.

KEY files are not meant to be opened. Instead, you can place the KEY file in the "licenses" folder in the LightWave 3D installation directory to register the software.

For example, to register LightWave 3D 10, place the KEY file in the following directory:

• Windows - [user]\​.NewTek\​LightWave\​10.0\​licenses\​
• Mac OS X - [user]/​Library/​Application Support/​NewTek/​LightWave/​10.0/​licenses/​

Although KEY files are not meant to be opened, you can open them with a plain text editor to view the license key.

In macOS and iOS, you can open KEY files with Apple Keynote. To open a KEY file with Keynote on a Mac, select File → Open... in Keynote. If you are looking to only view the KEY presentation, you can open it with Apple Preview, and each slide is presented as a static image.

You can also upload KEY files to the iCloud version of Keynote in your web browser (requires an Apple ID). This is helpful for Windows users who don't have access to the Mac or iOS versions of Keynote. In the iCloud application, you can view, edit, save, and download KEY presentations.

How do I open KEY files in Windows and Linux without an Apple ID?

Windows and Linux users who do not have an Apple ID can open KEY files with LibreOffice Impress. However, Impress users should be aware that the program often alters KEY files' original formatting. Impress also does not allow users to save presentations as KEY files. Therefore, if you make any changes to a KEY file in Impress, you must save the edited file as an .ODP or PPTX file.

Apple Keynote can convert KEY files to several different formats. In the macOS version, select File → Export To, then choose one of the following formats:

• .PPTX / .PPT PowerPoint presentation
• .PDF document
• .MOV or .M4V video
• .JPEG image
• .PNG image
• .TIFF image
• .HTML webpage
• Animated .GIF
• Keynote '09 presentation

You can also convert KEY files to PDF files with Apple Preview by selecting File → Export as PDF....

KEY files store variations of keyboards, whether it be because of different languages with unique characters or keyboard shortcuts for gamers and video editors. For example, a KEY file that stores an English keyboard layout may be named EN.key, and a KEY file that stores a Spanish keyboard layout may be named SP.key.

If the KEY file comes with an operating system, you will most likely be able to find it with the other system files. If you create a KEY file with a program, the application most likely saves the KEY file in the program installation directory.

Typically, the program or operating system that supports the KEY file references the file to map keys typed by a user to the appropriate function. If this is the case, the KEY file is not meant to be opened.

However, the KEY file may be saved in plain text, which means you may be able to open and modify it with a plain text editor. You can try opening a KEY file with a text editor to verify if this is the case. To do this, you may need to change the .KEY file extension to .txt before attempting to open it with a text editor, such as Microsoft Notepad or Apple TextEdit.

Because KEY files are plain text files, you can open them in any text editor, such as Microsoft Notepad (Windows), Apple TextEdit (Mac), or GitHub Atom (cross-platform). However, you should not edit the text your KEY file contains. Editing your KEY file will cause your web server or website to function incorrectly.

For instructions on how to use your KEY file with a web server as part of an SSL certificate, refer to your web server or certificate's documentation.

When a user attempts to unlock their Android device, the device checks the entered passcode, password, or unlock gesture against the data stored in the device's KEY file(s). Most users will never encounter or have to open their Android KEY files. However, forensic analysts who want to access a locked Android device sometimes use KEY files to determine the device's passcode, password, or unlock gesture.

KEY files are not meant to be opened. However, some forensic analyst software, such as GestureCrack, allows users to extract the unlock credentials a KEY file contains.
