Metadata

Metadata are information describing the content of the file they are part of. For example :

An important feature of Siren is its ability to extract metadata from files and use them in a rename expression through variables.

The information gathered depend on the file extension and, in a few cases, the platform you're using. Caution : by modifying or removing the original extension of a file, Siren may not extract its metadata anymore.

It handles a large file extension catalog : image, audio, video, office document, application package ...

Here is a categorized list of supported extensions :

If you are not interested in these metadata and want to save memory and CPU cycles you can disable their extraction in "Preferences/General".

At the same place, another option will enable you to choose if Siren has to try to detect the type of files whose extensions are invalid or unknown.
