Folders Modified
This window lists the folders that have files (directly beneath them, not necessarily in subfolders) that have been modified both as a result of being edited and also during the build process. This is to facilitate uploading just the modified portions of a large project to your website host.
These folder names are not cleared during subsequent builds, in case you build multiple times before finally uploading your content. The Clear All button removes everything from this list (only), under the presumption that the files have been uploaded and no longer need to be tracked.
Note that this list will be cleared when the program exits.
