What is a SHOW file?
A .SHOW file can be one of several different file types. Most commonly, it is a presentation slideshow file created by Hancom Office Show. It may also be identified as a Thinkfree Office NEO Show Document, which is developed by Hancom.
The .SHOW file extension is not limited to presentations. It is also used by the Showbie application for educational materials. In the live events industry, .SHOW files operate as lighting control show files used by MA Lighting grandMA software (including grandMA2 and grandMA3). Additionally, Pangolin Laser Systems uses this extension for laser and multimedia show data, often saved in a GZIP format.
How to open SHOW files?
You can open .SHOW presentation files using Hancom Office on Windows or Mac. If the file is a lighting show file, you need specific console software, such as grandMA3 onPC. Because multiple software programs use the .SHOW extension, you may need to try different applications to see which one works.
Best practices and troubleshooting
If you do not know the origin of your .SHOW file, do not blindly rename the extension. Instead, inspect the file contents. Many .SHOW presentation files use a standard ZIP format structure. You can create a copy of the file, rename the copy to use the .ZIP extension, and use extraction tools like 7-Zip or the `unzip` command in a terminal to view the internal XML and media files.
Software and tools
Standard desktop tools for these files include Hancom Office, Showbie, and grandMA3. Developers can also use scripting libraries like Python's `zipfile` module or `gzip` module to extract data from ZIP-based or GZIP-based .SHOW files.
Summary
viewer.online/show analyzes .SHOW files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because .SHOW files use the known ZIP format, viewer.online/show can safely open and display them online, eliminating compatibility problems.
