DDファイルとは？
A DD file is a compressed archive created by DiskDoubler, a discontinued file compression utility for Macintosh computers running Mac OS Classic. It contains one or more files compressed in the DD format, which uses the LZ78 compression algorithm to reduce the size of files. DiskDoubler compresses files in place, allowing them to be expanded automatically when opened without requiring a separate decompression step.
詳細情報
DiskDoubler worked in the background through a feature called AutoDoubler, which automatically compressed files as they were saved or modified. This made it convenient for users to save storage space while keeping files accessible for everyday use. Mac OS Classic users commonly used the software to maximize disk space on systems with limited storage capacity.
DDファイルの開き方
You can open DD files with various programs, including Smart Projects IsoBuster, The Unarchiver, and 7-Zip. These programs can extract the files from DD archives, allowing you to recover the original data or migrate it to current archive formats.
