How do I convert a .7z archive to ACE using this converter?

Open the 7z-to-ace page, pick your .7z file, choose ACE from the output drop-down, and click Convert. The service extracts the 7Z archive in memory, rebuilds the folder tree, then recompresses the files with ACE's LZMA solid compression. After it finishes, download the .ace archive and open it with WinACE or another compatible unpacker.

Why would I want to convert 7Z to ACE instead of keeping 7Z?

While 7Z gives better compression in most modern scenarios, ACE is still the native format for legacy WinACE-based backup systems, some industrial software, and old distribution disks. ACE's solid archive mode can occasionally achieve a smaller archive than 7Z on collections of small, highly similar text or config files because it reuses a single dictionary across all files, and converting lets you restore compatibility with those older tools.

Will converting 7Z to ACE preserve file timestamps, permissions, and folder structure?

The file bytes are copied losslessly, so the original content inside each file stays intact. The converter also preserves common metadata such as modified dates and the directory hierarchy. However, ACE's file header is older than 7Z's and doesn't support UTF-8 Unicode filenames or POSIX permissions; non-ASCII names may be converted to the system's legacy ANSI/OEM codepage, and Unix execute bits/owner info are not stored in the ACE archive.
