C01 File – What is .c01 file and how to open it?

C01 File Format

A C01 file is a split archive part 1 file, typically used by the WinAce file archiver. It is commonly encountered when large files are split into smaller parts for easier storage, transmission, or backup. The file extension .C01 denotes the first part of the archive, and subsequent parts may be numbered incrementally, such as .C02, .C03, and so on.

Usage and Characteristics

C01 files are primarily used to archive large files, making it manageable to store and retrieve them in parts. This is particularly useful when dealing with file sizes that exceed the limitations of certain file systems or transmission protocols. Additionally, C01 files can enhance data security by providing encryption features within the archive. When combined with a robust encryption algorithm, they offer a secure way to store sensitive information.

Opening C01 Files with WinAce

C01 files are split archive part 1 files used by WinAce, a popular file archiver for Windows. To open a C01 file, you must have WinAce installed on your computer. Once you have WinAce installed, you can open a C01 file by double-clicking on it. WinAce will automatically combine all the split archive parts and extract the contents of the archive.

Alternative Methods for Opening C01 Files

If you do not have WinAce installed, there are a few alternative methods you can use to open a C01 file. One option is to use a free online file extractor. There are several websites that offer this service, such as File-Extractor.com and Extract.me. To use an online file extractor, simply upload your C01 file to the website and the website will extract the contents for you.

Another option is to use a command-line tool to extract the contents of a C01 file. There are several command-line tools available that can do this, such as 7-Zip and PeaZip. To use a command-line tool, open a command prompt window and navigate to the directory where the C01 file is located. Then, type the following command:


7z x C01_file_name.C01


or


peazip -x C01_file_name.C01


This will extract the contents of the C01 file to the current directory.

C01 File Extension

The .C01 file extension is associated with WinAce, a file archiver for Microsoft Windows. It indicates that the file is the first part of a multi-part split archive. Split archives are used to break down large files into smaller parts, making them easier to transfer or store on limited storage space.

WinAce uses a proprietary file format for split archives, with the C01 file extension representing the first part of the archive. Subsequent parts use the extensions .C02, .C03, and so on. The C01 file contains the header information for the archive, including the total number of parts, the size of each part, and the compression algorithm used. The other parts of the archive contain the actual data.

To extract the contents of a split archive, all parts must be present and in the correct order. WinAce can automatically combine and extract the parts based on the header information in the C01 file. The extracted contents will form a single, complete file. To create a split archive, WinAce can automatically divide the source file into smaller parts and assign the appropriate file extensions.
