File Content Extraction 26.1
PDF Export SDK C Programming Guide

# ENdocAttributes

This enumerated type provides additional information about a file during auto-detection. This enumerated type is defined in `adinfo.h`.

NOTE: The attributes in this enumerated type are set when a particular characteristic is detected. However, if the attribute is not set it does not necessarily mean that the characteristic is not present. For example, File Content Extraction sets `kEncrypted` when it detects encryption on the file, but if it does not detect encryption it does not necessarily mean the file is not encrypted.

## Enumerators

`kEncrypted` | The file is encrypted. For container files, this is set if access to the entire container is protected. If only access to individual files within the container is restricted, this is not set.
`kMacBinaryEncoded` | The file uses the MacBinary encapsulation format. File Content Extraction will report this file as `MacBinary_Fmt`.
`kAppleSingleEncoded` | The file uses the AppleSingle encapsulation format. File Content Extraction may report the format of the contained file.
`kAppleDoubleEncoded` | The file uses the AppleDouble encapsulation format. File Content Extraction will report this file as `Apple_Double_Fmt`.
`kWangGDLencoded` | The file uses the Wang Office GDL encapsulation format. File Content Extraction may report the format of the contained file.
`kWindowRMSEncrypted` | The file is encrypted with Windows RMS encryption.
`kBigEndian` | Where a format has big and little endian variants, this value indicates that this file is in the big endian variant.
`kLittleEndian` | Where a format has big and little endian variants, this value indicates that this file is in the little endian variant.
`k32Bit` | Where a format has 64- and 32-bit variants, this value indicates that this file is in the 32-bit variant.
`k64Bit` | Where a format has 64- and 32-bit variants, this value indicates that this file is in the 64-bit variant.
`kSecloreEncrypted` | The file is encrypted using Seclore encryption.
`kSmartCryptEncrypted` | The file is encrypted using PKWARE SmartCrypt encryption.
