File type specification:
The qcif file extension is used for somewhat old QCIF RAW video format.
The qcif file has roughly 1/4 of the resolution of the CIF file. Seems like a variant of MPEG-4 format, optimized for very small resolutions and frames.
This qcif file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
