If you are try to upload a zipped file into eBinders by dragging it straight from the Finder application on a Mac into eBinders, you will most likely get an error. This is because the Finder only displays a preview of the files, it has not yet decompressed the zipped files. You can work around this by transferring the zipped file onto your desktop which will then decompress the files and allow them to be uploaded into eBinders. Or, if your Finder has an "Extract File" option, you can use that to decompress the files and then be able to upload them into eBinders.
