The dll1 file extension is associated with ASUS Express Gate (Splashtop), a lightweight operating system environment installed in the ROMs of some ASUS motherboards and notebooks. Express Gate provided a quick way to start a separate environment.
Express Gate functioned as a secondary operating system for Internet use and included its own software and data files. A dll1 file is one of the data files used by this environment; its contents are intended for Splashtop OS rather than for direct use by Windows or another desktop application.
The related software ran on Linux/Unix-based Splashtop OS.
A dll1 file is normally loaded by ASUS Express Gate and is not intended to be opened manually. To use it, leave it in the location and installation from which Express Gate expects to read it, then start Express Gate on the compatible ASUS motherboard or notebook.
Renaming the file or opening it with a text editor may damage or misrepresent its contents.
A dll1 file is an internal ASUS Express Gate data file, not a user document or interchange format. It therefore has no practical conversion to another file format.
If the goal is to preserve or move Express Gate, copy the complete original installation or system backup rather than converting individual dll1 files.
