You can make life a lot easier for editors by making a few adjustments for file downloads.
In the user TSconfigyou can set that the file size is displayed by default and the default layout is set:
##Download with filesize TCAdefaults.tt_content.filelink_size = 1 ##Layout for Download with icon TCAdefaults.tt_content.layout.types.uploads = 1
In the TSconfig page, you give the layouts a name so that the editor knows what to set:
#uploads alt labels TCEFORM.tt_content.layout.types.uploads { removeItems = 0,3 altLabels.1 = Icon altLabels.2 = Preview }
