# KFileMetaInfo Class Reference

`from PyKDE4.kio import *`

## Detailed Description

KFileMetaInfo provides metadata extracted from a file or other resource.

When instantiating an instance of this class, the metadata related to it will be retrieved and stored in the instance. The data can be inspected through KFileMetaDataItem objects.

## Enumeration Documentation

What

This is used to specify what a KFileMetaInfo object should read, so you can specify if you want to read "expensive" items or not. This is like a preset which can be customized by passing additional parameters to constructors.

Note:
  It is necessary to wrap members of this enumeration in a `WhatFlags` instance when passing them to a method as group of flags. For example: `WhatFlags( Fastest | TechnicalInfo)`

Enumerator:

  Fastest = 0x1 |
  TechnicalInfo = 0x4 |
  ContentInfo = 0x8 |
  ExternalSources = 0x10 |
  Thumbnail = 0x20 |
  LinkedData = 0x80 |
  Everything = 0xffff |
