[edit] Identifiers

For single-file archives, often the last letter of the filename extension is changed to "$". Sometimes an exclamation mark is used instead of the dollar sign, which appears to be the case when an archive with $ as the last name character already exists. For multi-file archives, the most common extensions seem to be .lib and .cmp. Many archives of this type have no suffix but $ as last character of file name. A few contain only a single file instead of several files.

[edit] Identification

Files begin with bytes: 65 5D 13 8C 08 01. At offset 8 the filename style byte is stored. The value 1 means without wildcard. This is typically the case for the single variant. The value 2 means with wildcard. This is the case for the other variant.
