Combining Commodore 64 disk images doesn’t require a deep dive into command-line tools or obscure software tricks. For Windows users, DirMaster by Style64 makes the process clear and fast—especially when dealing with multiple .d64 files.
In a recent video, YouTuber joezomby1 walks through the process of merging content from several C64 disk images into a new one, all within DirMaster’s visual interface. No scripting, no hex editing—just point, click, drag, and save.
DirMaster allows users to open multiple disk images side-by-side. You can easily browse each one, select the files you want, and drag them into a new disk image window. This makes it ideal for consolidating multi-disk games, organizing demos, or cleaning up disk compilations. The software shows directory blocks and available space in real time, so you’ll know if you’re about to exceed the limit of a standard 1541 disk.
joezomby1’s walkthrough highlights a few quick tips that can save time—like how to copy only the PRG files you need or keep file order consistent. Once you’re done combining, saving the new .d64 is just one click away. It’s a tidy solution for anyone wrangling scattered files from old projects, scene collections, or disk-based software libraries.
DirMaster continues to be a favorite among Commodore 64 users who prefer a clean, graphical workflow without the hassle of legacy file managers or emulator-based disk editors.
