Determine Format Support

After the file format is extracted, the detection module then uses an initialization file (kvsdk.ini) or the Windows registry to determine whether the format is supported by KeyView, and the appropriate structured access layer and reader to load. See View Initialization Information for more information.

The initialization file and Windows registry contain the following information:

Below are some entries from the initialization file. The entries in the initialization file or the Windows registry list each format value, and the reader used to parse that format.

180=afsr.dll
232=afsr.dll
236=htmsr.dll
272=htmsr.dll
355=htmsr.dll
328=foliosr.dll
294.2.0.9.0=l123sr.dll

For example, the final entry specifies that a Lotus 1-2-3 Spreadsheet file version 9.0 is parsed by the Lotus 1-2-3 reader, l123sr.dll.

NOTE: The information in the initialization file and Windows registry applies to all formats except graphics. Detection of graphics formats is handled by an internal module named KeyView Picture Interchange Format (KPIF).
