Detailed Description

This is an entry of file list. Each directory has such a list for fast search & modification. This structure was introduced because on-disk equivalents have variable sizes & record formats.

◆ FI_Flags

uint8 _DIR_INDEX_ITEM::FI_Flags

Set of flags. This is intended for internal use. Valid flags:

  • UDF_FI_FLAG_FI_MODIFIED
    Presence of this bit means that given FileIdent was modified & should be flushed.
  • UDF_FI_FLAG_SYS_ATTR
    Presence of this bit means that given entry of file list contains valid file attributes & times in NT-specific format.
  • UDF_FI_FLAG_FI_INTERNAL
    Presence of this bit means that given entry represents the file used for internal FS purposes & must be invisible.
  • UDF_FI_FLAG_LINKED
    Presence of this bit means that related FileEntry has more than one FileIdent. It happends when we use HardLinks.

Referenced by UDFGetBasicInformation(), and UDFSetFileXTime().

◆ Length

uint32 _DIR_INDEX_ITEM::Length

Specifies on-disk size of FileIdent. 0 value of this field means that given entry has no on-disk representation (ex. - pointer to the directory itself). In this case Offset value must be also 0.
