yooWeb 1.0 for Mac was available as a free download on our application library. The software is included in Internet & Network Tools.
From the developer:
yooWeb allows you to add online content directly to your FileMaker databases, including images, financial data, scientific data, and more. Supported image formats include JPEG, GIF, and PNG.
With yooWeb you can download or upload data using HTTP, HTTPS, and FTP. yooWeb's support for submitting forms (both get and post, including multipart forms with file uploads) allows you to interact with online software.
You may want to check out more software for Mac, such as Arch, Opera Update Checker or AmazonSearch, which might be related to yooWeb.
