This entry details my data archaeology work on the Mitsubishi WINCAPS/CAPS (Computerized Automatic Part Searching System) software developed by and/or for Mitsubishi Motors Corporation.

Pretty sure there is a DOS CAPS, or at least DOS access layer to database given the two strings in

IDX - Index
Index files are broken up into 2048 byte chunks, which I will refer to as "pages". Index file must be at least 1 page in size, meaning the smallest IDX file will be 2048 bytes, filled mostly with null bytes(00h) if it has 1 or 2 indexes (there are 60 indexes per page in SHARYO.IDX for example).
Header
The first 32 bytes of each page is the "header". The header's first 8 bytes contain the filename, if the filename is less than 8 bytes the remaining bytes will be padded with 20h. After the name is "IDX", followed by 00h as a seperator.
Byte 13 (14th byte) is the "page number", starting with 01h and incrementing each page.
Bytes 14-32 appear to be other informational flags which have yet to be understood.
| Byte # | Description | 
|---|---|
| 0-7 | Uppercase ASCII, matches file name, if name < 8 bytes it is padded with 20h | 
| 8-10 | 49h 44h 58h, literal: "IDX", Uppercase ASCII | 
| 11 | Always 00h, separator or null byte for the string? | 
| 12 | Always the same in all headers that are in the same file, often seen: 09h 11h, is this multiplier or record length? | 
| 13 | The "page" count, starts at 01h increments by 1 every "header" | 
| 14-31 | Other flags | 
| 15 | 00h or 01h or 02h, always set with byte 16? Always the same as byte 16? | 
| 16 | 00h or 01h or 02h, always set with byte 15? Always the same as byte 15? | 
| 18 | Secondary counter, starts at 01h and increments by 01h, always used with bytes 15 and 16 set? | 
| 22 | Number of records on this page |
