I have the following path set up for external files: E:\TMG Exhibit Source Repository\ and 3 subfolders named "Audio Clips", "Images People" and "Images Other" in which the particular files are placed. For many years, have only had "Images People" files. Just started to put files into the "Images Other" sub-folder. Can look at the "Properties" --"Info" and all is ok. In other words both paths work ok.
In the "Files">"Preferences">"Current Project Options">"Advanced", the "Exhibit Folder" shows: "E:\TMG Source Repository/Images People\". When I now do a backup, the Images in the People files folder are saved as before but the Images in the Other Files folder are not saved. Before I changed anything, thought I would check first. Must the Exhibit Folder path end with the sub-folder containing the files or will changing the Exhibit Folder path to "E:\TMG Source Repository\" allow access to all three sub-folder files?
A minor point (since it has been working) is that even though the Advanced root folder name is "TMG Source Repository" and the actual name is "TMG Exhibit Source Repository" backup does save the Images People files!
