EDI Install archive refers to a compressed file format associated with later versions of the EDI Install Pro installation software for Windows 3.x. EDI Install Pro was developed by Eschalon Development and Robert Salesas.

Discussion

The documentation implies that the format was introduced in EDI Install Pro v2.8. It is the successor of EDI Install packed file.

Registered users of the software received an ARCHIVE.EXE utility to create such files, and a redistributable EXTRACT.EXE utility to decompress them individually.

The default file extension is .$00. In case of a name conflict, .$01, .$02, etc., will be used.

The format also supports file splitting. Fragmented files use extensions .@00, .@01, etc.

Identification

Files start with ASCII "ARCV". This does not distinguish them from Eschalon Setup archive.

They seem to contain the string "CHNK", at the offset given by the byte or integer at offset 6.
