What is the QD4 file format?
A file with the .QD4 extension is a file known as Omnis Quartz Segment 4 Data. It belongs to the Database Files category. This format is associated with N/A.
The reliable way to open a .QD4 file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .QD4 files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
