Use the Manage Files window to Rename, delete or remove bad files.
The Manage Files command in the Do Menu, brings up a window that allows you to alter your files. Select a file in the list and press delete to remove a file. Since set lists can refer to files, all set lists that reference the deleted file will be changed. The deleted file entry will be removed from the set list. If a set list contains a single reference to the deleted file, the set list will be deleted. You can also rename files by selecting the file and choosing the Rename button. Delete Bad Files will attempt to remove all bad bookmarks that reference non-existing files and will remove bad entries in set lists as well. All bookmarks/set lists should be in sync with the current pdf files that you have on your iPad. You can also rename lists (they have an extension .fld) and indexes (extension .csv). If there is a zip file, you can extract the files in the zip to your unrealBook documents folder. You can choose to only save the files not found, or to overwrite your files with the files found in the zip file.
