You may have to move some or all indexed PDF documents to a network server, disk or web site. An index definition contains relative paths between the index definition file (ZPI) and the folders containing the indexed documents. These relative paths must be kept unchanged so that the index will still work after the move.
It is best if the ZPI file and the folders containing the indexed documents are in the same folder, then you can maintain the relative path simply by moving that folder. Otherwise, you might have to create a new index file after you move the indexed document collection.
You can still use the original ZPI file. First move the indexed documents to your target location. Then copy or cut the ZPI file to the new index folder, edit options, then create an index using the Catalog dialog box. See Creating a Search Index.
If the index was stored on a drive different from any part of the collection it indexes, moving the collection or the index makes it unusable. If you plan to move a document collection to another network location or onto a CD, create and build the index in the same place as the collection.
