DataSpider allows you to upload Zip files, but it does not support encrypted or password protected Zip files.
■Workaround
After extracting a password protected zip file, please upload it by specifying the extracted folder directory in [Explorer]-[File]- [Upload directory/file]
After extracting a password protected zip file, please recompress into a zip file without setting any password and then upload it by [Explorer]-[File]- [Upload directory/file]
