Split multi-volume ACE compressed file archive
File type: Archive and compressed file
A .c52 file is one volume of a split, multi-volume ACE compressed archive created by WinACE.
It is not a complete archive on its own. The other volumes, including the first .ace file or self-extracting executable, are required to extract the archived files.

The .c52 file extension is associated with WinACE, an archive and compression utility for Microsoft Windows. It identifies an additional volume in a multi-volume archive that uses the ACE format.
ace is the native archive format of WinACE. When a large archive is split into smaller volumes, WinACE normally uses an .ace file or a self-extracting executable for the first volume, followed by files named .c01, .c02, .c03 and so on. The .c52 file is one of these additional volumes.
WinACE also supports other common archive formats, including ZIP, RAR and MS-CAB.
To extract the archive, all volumes must be in the same directory. Opening the first volume in WinACE allows the program to read the remaining parts and extract the archive contents.
Place the .c52 file and every other volume of the same archive in one directory. Open the first volume - normally the .ace file, or the self-extracting executable if the archive starts with one - in WinACE.
Do not open the .c52 file as an independent archive. WinACE uses the complete set of volumes to extract the files.
A single .c52 file cannot be converted independently because it contains only part of a multi-volume ACE archive.
After obtaining all volumes, extract the complete archive with WinACE and create a new archive in another format with an archive utility that supports that format.
