Note Note for researchers working at the MPI for Psycholinguistics, Nijmegen: Please specify only the name of the file – do not make use of the open folder icon to the right of the Link field. The name of the media file should be the same as the name of the IMDI file (see Section 1.2.1.12), and as the name entered in the field Session Name (see Section 2.1.1). Furthermore, the file name has to be Unix compatible: do not use file names longer than 14 characters, do not use non-letter or non-number characters (except for the underscore: _), and do not use blank spaces.

The (approximate) size of the media file in bytes. Note that this field is not standardized: it is meant to be read by humans (to give them an indication of the size before they, e.g., download it), not to be processed through the computer.
Type

value comments Format
The format of the media file. Choose a value from the pull-down menu, or type in an alternative value.
