Chapter Six — File Functions (continued)
It is frequently desirable to know what type of data a file contains. The file’s extension can give a glue but can also be ambiguous. To dig deeper, a program must examine the content of the file and look either for an explicit signature or certain clues as to the content.
The file type testing only covers a fraction of all the file types using in Windows, Unix and other systems. Further, some tester operate on file extensions only such as Word or Excel.
The underlying application uses file type codes to represent a file’s type. File type codes, in binary form, are actually a complex set of bits that help to classify the file type and identify it’s content. When the content is examined, more type information is available and certain content data is also extracted. The codes can also be represented as a string token.
The file type codes consists of a series of bitwise values. Note that the top bit (0x80000000) is never set so is to avoid a file type code being confused with an formatted error code. The first portion of interest is the class or FT_CLASS_MASK (0x0000F000). This classifies files such as spreadsheets and document files. The specific type of file is contain in the type FT_TYPE_ORDINAL_MASK (0x00007FFF). A flag is set on various file types, FT_A (0x00008000) to indicate whether the file is ANSI or ASCII based (it could also be UTF but can be opened in a text editor).
Certain types of a variation as set by the FT_VARIATION_MASK (0x0E000000) to indicate sub types such as an XBRL schema file.
Finally, a file type may contain version information. For this reason, direct comparison of codes may not be practical.
