HLSW Game Server Tool is a Windows application for online gamers that provides tools for finding and managing game servers. The software was developed by Stripf Software.
An SL15 file contains data used internally by HLSW. It should be treated as an HLSW support file rather than edited manually.
Open an SL15 file with HLSW Game Server Tool on Microsoft Windows. The file is normally read by the application from its expected location rather than opened as a separate document.
If HLSW does not recognize the file, keep it in its original folder and avoid changing its extension or contents.
There is no standard conversion for the SL15 file format. It is an internal HLSW data resource, not a general-purpose document or media format.
Do not convert the file by renaming its extension.
