A .C10 file acts as segment 10 in a divided archive, and cannot extract on its own because key structure info resides in earlier parts; matching .c## files and equal-sized volumes indicate a split archive, and opening .c00 is the correct way to trigger reconstruction,...
A .C10 file represents a midstream piece of a multi-volume ACE package, containing only part of the compressed data; the presence of similarly named .c00–.c## files confirms a split set, and extraction must start from the first chunk, with .c10 alone offering no...
