What is an .SQ3 file?

.SQ3 file extension has been classified as Database Files.

.SQ3 is oml2-server database

The sq3 file extension is used by oml2-server for its database files. A oml2-server (OML2 Server) is the daemon program for OML.

The OML2 Server seems to be obsolete product without support from developer, or producer.

The sq3 database format seems to be similar to SQLite.

.SQ3 file format is deprecated and this file format is no longer supported.

Currently, .SQ3 file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.


How to open:

Try any SQLite database viewer to view content of *.sq3 files.

How to convert:

As far as we know, this .sq3 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
