What is the .SQI File Extension?


.SQI File Extension Description:

The file format SQI stands for Squish Query Index File, which is a message base index for processes created under the second version of Squish Developers Kit, otherwise known as SDK.

The SQI file format is a rather old file format type used in program development during the early 90's. Structured after the C programming language, the file structure of .sqi file extension types are very similar to that of their predecessor.

The message base index characteristic of the SQI file type is one of the two components of a Squish file. The other one is the data file that consists of the bulk and the majority of the source code referenced to the program project being developed. The file extension .sqi holds the simple array of index for Squish records.

The simple array structure of a Squish message base index is characterized by simple integer numbering, which is sequentially attributed to its corresponding message. Starting from 1 to the last existing message entity, these messages in the index do not need to be restructured every single time they are accessed and referenced.

However, the simplistic sequence of the .sqi file extension type makes it quite difficult for system developers and debuggers to manually look for a specific message, especially if the .sqi file format has amassed a large number of index messages for the Squish program.

Later versions of the Squish Developers Kit have included the support for a Unique Message Identifier (UMSGID) for each message that is indexed in an .sqi file type. This means that each newly added message entry in an .sqi file is assigned with a unique 32-bit identifier, which acts as a tag for later referencing. This ID takes up 4 bytes and follows the standard rules of being assigned a header, and referenced along with other fields. This is extremely helpful for system developers when searching for a specific line in the SQI file format code.
