What is MIME type "application/x-sas-data-index"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/x-sas-data-index is a MIME type used for index files in SAS data sets. It holds information that points to specific records within large data files, making data searches faster and more efficient.

These index files work with SAS software. They are generated as companions to the primary data files. The MIME type ensures that applications know how to process the index data internally without displaying it directly to the user.

• Main Use: Provides rapid lookup pointers for fast data retrieval in large SAS data sets.
• Functionality: Improves query performance and speeds up sorting and merging tasks.
• Associated Files: It is used with files like SAS7BNDX and SI7.
• Designation: The "x-" in the MIME type indicates that it is a non-standard, proprietary format used specifically by SAS.
