How to decompress and access a 10 year old ACE file?

Question

I'm trying to unarchive some old photos I have that are stored in ACE format (via WinACE). The file was created a little over 10 years ago.

I'm running unace l photos.ace and getting what seems to be a full list files.

When I run unace e photos.ace I and am getting an error.

The output is:

UNACE v1.2    public version

Processing archive: photos.ace

File compressed with unknown method. Decompression not possible.

Error occurred

Does anyone have any suggestions/ideas on how to extract these?

Edit: I've downloaded the linux version (v2.5) from winace.com's site with the same effect.

Answer 1

You can try the unace-nonfree package.

Answer 2

You might want to try WinAce in wine or a VirtualBox.
