No reliable information identifies the creator, contents, or intended use of the .do_ file extension. It is therefore not possible to assign the file to a particular vendor, application, or platform.
No specific program is known to open .do_ files. Opening the file in a plain-text editor may reveal readable content, but a binary or application-specific file may require the software that created it.
The source of the file or the application that supplied it is the best way to identify a suitable program.
No specific converter can be recommended because the format and file contents are unknown. Conversion should be performed by the original application, if that application supports exporting to another format.
