What is an SPL file?
An SPL file is an animation created by FutureWave FutureSplash Animator, a now-discontinued multimedia authoring tool from the mid-1990s. It stores vector-based information about an animation, including text, shapes, graphics, colors, and metadata.
More Information
FutureWave designed FutureSplash Animator to create compact and scalable animations that developers could embed into websites or users could view in compatible players. Macromedia acquired FutureWave in 1996, which Adobe later acquired in 2005. Adobe turned FutureSplash Animator into Adobe Flash, which supported SPL files until Adobe discontinued it when modern web standards like HTML5, CSS3, and JavaScript became prevalent.
How to open an SPL file
You can open SPL files with Adobe Flash and Adobe Flash Player, although both programs are discontinued. To open an SPL file with either program, select File → Open.

An SPL file may also be a file created by Windows when a user submits a print job. It contains the spooled print data, which includes the digital document contents sent to the printer for printing.

An SPL file contains a program written in the Shakespeare Programming Language (SPL). The program consists of source code that resembles the script of a play. It can be run with the shakespearelang interpreter.
More Information
The Shakespeare Programming Language is an esoteric programming language whose structure is modeled after the Bard's plays. Each program contains characters, acts, scenes, actions, and dialogue that determines its output, by adding positive values to characters using positive nouns and adjectives and adding negative values to characters using negative nouns and adjectives.
For example, an SPL file might introduce Romeo and Juliet, have them enter a scene, speak, and exit the scene. When run using an SPL interpreter, this program would likely output a simple line of text.
How to open an SPL file
You can open and edit an SPL file with Microsoft Visual Studio Code (multiplatform) or any other text editor. You can use the shakespearelang interpreter (multiplatform) to run the program an SPL file contains.

An SPL file may also be a spelling dictionary used by Vim, a popular Linux text editor. It contains a language-specific dictionary used to provide spell check functionality in Vim. SPL files are stored in Vim's ~/vim/runtime/spell directory.
More Information
Like many text editors, Vim (and its variants) contains spell check functionality that highlights users' spelling mistakes. To turn on spell check, Vim users must either enter the command setlocal spell in Vim's command line or add the set spell command to their .VIMRC file.
By default, Vim uses English spelling dictionary files, named en.characterset.spl, to check users' spelling. However, users can modify their VIMRC file's set spelllang setting to use other languages' spelling dictionaries. Vim contains over 100 SPL dictionaries, grouped into over 50 languages. In addition to these SPL files, Vim uses SUG and DIFF files to highlight misspelled words and show spelling suggestions.
How to open an SPL file
Vim SPL files are not meant to be opened. If you want to use an SPL file as your Vim spelling dictionary, you can do so by:
- Opening your Vim VIMRC file.
- Updating the set spelllang setting to use your SPL file's language code. For example, if your SPL file is named fr.latin1.spl, update the setspelllang setting to read set spellang=fr
If necessary, you can download SPL files (as well as each language's SUG and DIFF files) from ftp.vim.org.
