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. There are other programs that provide access to disk and file archives, but none have as many features or support as many formats as CiderPress.
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.
Key features:
Download CiderPress v3.0.1 (4-Jan-2009) as a Win32 executable.
A tutorial is available, with some sample files. In addition, Walt Perko has created an animated GIF (1.8MB) demonstrating how to put a 32MB ProDOS volume onto a CF card for use with a CFFA (useful if your Apple II isn't able to format the CF card first).
