Downloaded zip file is empty ← Troubleshooting When clients download an entire collection, the images are saved in a ZIP file. If your images have special characters, such as "©", "|", "§", "ñ" or extra "." in the filename, these images might not show up correctly on Windows machines with the default extracting program. You can correct this by removing any special characters in the filenames. If the problem persists even when your files have no special characters, please contact us at firstname.lastname@example.org.
