Extract text from WinAce archive parts (C10)
To convert C10 archive parts to another format, you need WinAce or other Compressed software.
To convert other file formats to the "Split Archive Volume" file type, you need software like WinAce or a similar tool.
A .c10 file is the 11th part of a split compressed archive created by the now-obsolete WinAce software. When a user needed to store a massive file across multiple CDs or floppy disks, WinAce would slice the archive into smaller sequential volumes: C00, C01, up to .C10 and beyond.
Historically, these files were managed by WinAce or extracted using prominent archivers like WinRAR.
The .c10 format is severely problematic today. It is a proprietary, closed-source format that has been completely abandoned. More importantly, in 2019, a critical remote code execution vulnerability (CVE-2018-20250) was discovered in the UNACEV2.DLL library used to unpack these files. Because the source code was lost by the original developers, major archiving tools like WinRAR permanently deleted their support for ACE and C10 files to protect their users. Furthermore, a .c10 file is completely useless on its own; you must have the master ACE or C00 file, along with all other numbered volumes, sitting in the exact same folder to even attempt an extraction.
If you manage to safely extract the contents, you should immediately re-compress those files into a safe, open standard like ZIP or 7Z. This prevents future access issues, ensures native compatibility across Windows and macOS, and completely avoids the severe legacy security risks.
Because of the deprecated extraction libraries and the split-volume requirement, standard online converters fail to process .c10 files. We can safely inspect the file's internal headers, bypassing the vulnerable .dll files, to show you raw text or metadata. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your C10 file, detects the exact format, and lets you read the text inside.
Users also converted D10, T10 and DF10 files.
If you want to convert C10 file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use WinAce or similar software from the "Multi-volume File Compression" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to C10, try WinAce or another comparable tool in the "Multi-volume File Compression" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our C10 converter.
