The ov4 file extension is mainly related to DOS overlay files. When running in a 640K MS-DOS machine, all program code may not fit into available memory at the same time.
To overcome this memory limitation, most large programs use overlays. An overlay is a portion of the program code that shares memory for its code with other code modules. (part of program to be loaded when needed), program code for DOS.
This ov4 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.
