Open:
- formatIndex >= 0 (exact Format)
1) Open with main type. Archive handler is allowed to use archive start finder.
Warning, if there is tail.
- formatIndex = -1 (Parser:0) (default)
- same as #1 but doesn't return Parser
- formatIndex = -2 (#1)
- file has supported extension (like a.7z)
Open with that main type (only starting from start of file).
- open OK:
- if there is no tail - return OK
- if there is tail:
- archive is not "Self Exe" - return OK with Warning, that there is tail
- archive is "Self Exe"
ignore "Self Exe" stub, and tries to open tail
- tail can be open as archive - shows that archive and stub size property.
- tail can't be open as archive - shows Parser ???
- open FAIL:
Try to open with all other types from offset 0 only.
If some open type is OK and physical archive size is uequal or larger
than file size, then return that archive with warning that can not be open as [extension type].
If extension was EXE, it will try to open as unknown_extension case
- file has unknown extension (like a.hhh)
It tries to open via parser code.
- if there is full archive or tail archive and unknown block or "Self Exe"
at front, it shows tail archive and stub size property.
- in another cases, if there is some archive inside file, it returns parser/
- in another cases, it retuens S_FALSE
- formatIndex = -3 (#2)
- same as #1, but
- stub (EXE) + archive is open in Parser
- formatIndex = -4 (#3)
- returns only Parser. skip full file archive. And show other sub-archives
- formatIndex = -5 (#4)
- returns only Parser. skip full file archive. And show other sub-archives for each byte pos
