It may prove necessary to change the location of cached data (download data from signbank) from the special ELAN data folder (see 1.1.2. Special ELAN data folder) to elsewhere, because this data may take a great amount of space. See below for how to do this.

It can be set in the Preferences tab of Edit > Preferences>Edit Preferences. At the item 'Location of cached data' click Browse... and navigate to a new folder in a different location than the default and click Select. The X restores the default file location.
