The document has a recognized file format but is corrupt.
fiPartiallyEncrypted = 0x0020
A portion of the document is encrypted.
fiPartiallyCorrupt = 0x0040
A portion of the document is corrupt.
fiOutOfMemory = 0x0080
There was insufficient memory to process the document.
fiOpenFailed = 0x0100
The document could not be opened due to a file open failure.
fiFilteredBinary = 0x0200
The document is in an unrecognized format and is being indexed using the binary filtering algorithm.
fiImageOnly = 0x0400
The document contains images without text, other than metadata and annotations. This flag can be used to detect image-only PDF files, but it is not a perfect indicator because a file could need OCR and still have some text in it. For example, a PDF file may have one page with text and 10 pages of scanned images, or it may have scanned images and a bit of text (but not the text of the scanned images) on each page.
