About ACE
Marcel Lemke's ACE came in 1998, and WinACE made it a rival of RAR, packing tighter than ZIP on the downloads, game releases and CD-ROMs of the time. A big archive was split into volumes: the .ace first, then .c00, .c01 and on.
ACE 2 added modes that pack pictures, sounds and programs by what they are. WinACE's last versions came with adware, and in 2019 WinRAR dropped ACE after a flaw was found in the old library it read it with, so most apps no longer open it.
Filepeek reads ACE 1 and 2 with a port of acefile, every mode, solid archive and volume, lists its files like a folder and opens the one you pick. A locked archive asks for its password, and Save as ZIP turns it into a ZIP that any computer opens.

Questions
Why won't WinRAR open my ACE file?
WinRAR dropped ACE in 2019, after a flaw was found in the old library it read ACE with, and 7-Zip never read it. Filepeek reads it with code of its own, which that flaw doesn't touch.
How do I open an ACE split into .c00 and .c01 files?
Drop the .ace together with all its .c00, .c01 and later parts. They open as one archive, its files listed like a folder.
Can I open a password protected ACE?
Yes. Filepeek asks for the password when you open a locked file, and it stays on your device.
Can I turn it into a ZIP?
Yes. Choose Export, then Save as ZIP. Phones and computers open the ZIP without an app.
Can I change what's in an ACE?
Yes. Remove, rename or add files right in its list, then Save as ZIP makes a ZIP with your changes. The ACE you opened stays as it was.
