Can EasyCatalog search in sub-folders for images?

EasyCatalog will only search in the folder that you have specified in the Field Options for the field. This is mainly for performance reasons, as searching sub-folders each time an image is placed could adversely affect performance. However, if the path to the image can be determined using the content of other fields then custom field functions can be used in the ‘Location’ field.

In this example, 'FIELDSTR(brand)' will be replaced with the content of the ‘brand’ field to build the path to the image.

Alternatively, the “Search for Content” menu option can be used to import images that failed to import. After all of your image boxes have been tagged with the relevant field, use the “Search For Content” menu option to begin searching the file system for the image to import.
