I chose to load a folder of 25 images. Just like the 2020 version, this 2021 version does remove the EXIF information but the pointer remains spinning. I let it go for 3 hours, then stopped it.
Another attempt with the same folder looked the same with the spinning mouse pointer circle. With the pointer still spinning, I did a “Save As” at 100%, and it did save the files without EXIF information. What I did not like about this “Save As” is that the program starts out allowing the user to migrate to the folder to save the images in, starting with My Computer. When I reached where I wanted a sub-folder, I learned that there is no “New Folder” option, so I had to go create it outside the EXIF-CLEANER program, then return to continue navigating into the new folder.
Next, I tried a Reset. The screen cleared, but nothing was ever redisplayed. My final option was the Exit the program and forget-about-it.
