# Filter Presentation Files to a Logical Reading Order

With some file formats, for example Microsoft PowerPoint presentations, the order of the text inside the file has no relation to the layout of the text on the page or screen. Recently modified text might appear at the end of a file, even though that text belongs at the beginning of the document.

You can configure KeyView to process position information and sort the extracted text so that it is returned in the correct (reading) order.

NOTE: This feature supports Microsoft PowerPoint files only.

To enable logical reading order

- In the C API, call the function `fpSetConfig()` and set the flag `KVFLT_FILTERLOGICALORDER`. For more information, see fpSetConfig().

- In the `formats.ini` file, find the `[Options]` section, and set `LogicalOrder` to 1. (This is an alternative approach - you do not need to do this if you have configured this feature through the API).

  For example:

      [Options]
      LogicalOrder=1
