One common situation when I use STG FolderPrint Plus is doing a search on my graphics folder, and have a whole bunch of results that are inside ZIP files. I don't want to extract them because these are very large ZIP files, with ten of thousands of items (icons in different file types and resolutions or graphic packs mostly).
For the graphics outside the ZIP files, since a few version backs you can preview while using the Search screen. But for each file found inside a ZIP file, I open the ZIP file, find the specific file, and open it to check it out.
But now, on the first feature of FPP 4, it can also preview files inside ZIP files – so you can just click the file, and get your preview right into the program.
FPP 4 will be made available when more new features are ready.
