Yes, reindexing the directory adds (and optionally removes) files wich were/were not present when the asset feed was setup.
We have an existing directory of files which are downloadable by another service. We would like to make (and have made) that directory available as an asset feed in Proget.
It's easy enough to point Proget to the existing directory for the feed, and have it index it. This creates the metadata within your system, making the files available to those users who are valid to download them.
If I were to add files via a drop directory, it would work, but it would not necessarily add them in the structured manner we have setup in the base directory. Although TBH I haven't tried dumping a directory tree into a drop directory to see what happens. I'll try that. Thanks.
