If you have collections of files, for example, work over successive months or even years which constitutes a project, you might have difficulty finding the data for specific topics later on. Using Disk Tree, you can capture the names and locations of all your project files, and whenever you need you can search the data base you have created in order to find what you are looking for. As the name "Disk Tree" suggests, the app was originally created to handle the contents of a series of DVDs (which are not so commonly used nowadays), but in fact is can be used equally to capture chunks of data from any source - e.g. from pendrives or the HD itself - as long as those chunks are not gigantic. Personally, I use it to take snapshots of all my software projects, which I save regularly in blocks such as "Proj_2024_A", "Proj_2024_B", and so on. After many years, when I seach back to see what I have done in the past, I am often surprised at what I find and had forgotten about!
Displaying and distributing photos is far less of a problem nowadays than it was in the past, when this app was written. However, for me, it still has its uses. Its primary use is as a means of displaying a series of photos to an audience, big or small, either automatically with a timer, or manually, one by one at the appropriate time. Optionally, there are different transitional effects which can be used between one photo and the next.
As I said, you probably use WhatsApp or some of the dozens of applications available nowadays to distribute your photos. However, with the Supershow it is very simple to export your slideshows in a form that can be used on the Internet, permitting your viewers to see the photos on their PC or on their smartphone. That said, it is only practical to do this if you have your own website.
