CiderPress provides the features that Apple II enthusiasts need to manage their disk and file archives. Open them, view their contents, and copy files between them.
CiderPress, introduced in March 2003, was developed and sold as shareware by faddenSoft, LLC. The program was made free, and the source code released under the BSD license, in March 2007. A “refresh” to modernize the code was just released.
