Split multi-volume ACE compressed file archive
File type: Archive and compressed file
A c50 file is one volume of a split ACE compressed archive created by WinACE. It is not a complete archive and normally cannot be extracted by itself.
The c50 file is an additional volume in the archive's sequence, which begins with an .ace file or a self-extracting EXE file.

The c50 file extension is associated with WinACE, a Windows archiving program. It identifies an additional volume of a multi-volume archive in the native ACE format. In this sequence, the c50 file is normally the continuation volume numbered 50.
WinACE creates smaller volume files when a large archive is split. The first volume uses the .ace extension, or an EXE extension for a self-extracting archive. Additional volumes use extensions such as .c01, .c02, .c03 and so on, including .c50. The archive content is distributed across all of these volumes.
ace is WinACE's native compression format. WinACE also supports other archive formats, including ZIP, RAR and Microsoft CAB.
To extract the archive, all volume files must be placed in the same directory. Extraction is started from the first .ace or self-extracting EXE volume, and WinACE then reads the remaining volumes, including the c50 file, automatically.
A c50 file is only one part of a WinACE split archive. Place it and every other volume from the same archive in one directory, then open the first .ace file or self-extracting EXE volume with WinACE on Microsoft Windows.
Do not open the c50 file as though it were a complete archive. WinACE needs the first volume and all subsequent volumes to extract the archived files.
A single c50 volume cannot be converted independently because it contains only part of the multi-volume archive. Obtain all volumes and open the first .ace or self-extracting EXE volume in WinACE.
After extracting the complete archive, the files can be repacked in another archive format with WinACE or compatible archiving software. This creates a new archive rather than converting the c50 file itself.
