To calculate the size in MB of selected folders in your Sources panel, right-click on the folder and go to Show folder size. The size of the selected folder and all subfolders will be shown as a preﬁx to the folder name, and folders will automatically be sorted by decreasing size. Note that the size may include documents not visible in the folder. For example, referenced documents (e.g. sequences in alignments, or documents with aliases) are not removed from the database when deleted, until the documents which reference them are also deleted. The folder size will not automatically update with changes to folder contents and can be removed by unchecking Show Folder Size, or by restarting Geneious Prime.
