The Infinity Engine is a computer game engine developed by BioWare for isometric computer role-playing games. It was developed for Battleground Infinity, which later became the first installment of the Baldur's Gate series.
BioWare used the engine in subsequent games and licensed it to Interplay's Black Isle Studios. The engine's games use several types of resource files, including SPL files for spell definitions.
An SPL file can describe mage spells, priest spells, innate abilities, special abilities and the effects associated with them. The game uses these resources to provide spell names, behavior, targeting and other gameplay data.
The format is a legacy resource format associated with the original Infinity Engine games and their modifications. It remains relevant when working with those games and their community-created content, but it is not a general-purpose spell format.
An SPL file is normally loaded automatically by the associated Infinity Engine game and is not intended to be opened as a standalone document. On Microsoft Windows, Baldur's Gate, Baldur's Gate II, Icewind Dale or Planescape: Torment can use the file when it is installed in the appropriate game resources.
For inspection or modding, use an Infinity Engine resource editor such as Near Infinity or DLTCEP. These tools can display and edit the spell data rather than presenting it as ordinary text.
There is no useful standard conversion from an SPL file to a common document or game format. SPL files are game resource files, so they should generally remain in their original format.
An Infinity Engine modding tool can edit an SPL resource and save a compatible version for a supported game, but this is an edit or game-specific adaptation rather than a general file conversion.

The spl file extension is related to the Macromedia FutureSplash Animator.
FutureSplash Animator was a software product for creating vector-based animations, the predecessor of Flash.
It was developed by FutureWave Software, a small software company whose first product, SmartSketch, was a vector-based drawing program for pen-based computers. In 1995, the company decided that they should add animation capabilities to their product and deploy it over the burgeoning World Wide Web.
The only way to create such animations on the web at the time was through the use of Java, but this was quickly replaced with the debut of Netscape's plug-in architecture.

Split File Shell Extension is a Microsoft Windows utility that integrates file-splitting functions with the Windows shell. It creates .spl files when a file is divided into smaller parts.
These files contain portions of the original file and are intended to be used together. The utility can join the parts to reconstruct the original file. The .spl format is specific to this file-splitting software rather than a general-purpose archive format.
A .spl file is not normally opened as an independent document. On Microsoft Windows, use Split File Shell Extension and its shell commands to join the complete set of split files and restore the original file.
Keep all parts created from the same source file together. Opening one part alone will not provide the complete original content.
There is no meaningful direct conversion from a .spl file to another file format because it is only one part of a split file set.
Use Split File Shell Extension to join the parts and recover the original file. The recovered file can then be converted or compressed with software that supports its actual format.
