A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .s01 Files
S01 files are AccessData encrypted disk images.
They use the MIME type application/octet-stream, which means they are binary files storing data in a non-text format.
- Forensic imaging: They capture complete disk or partition images in an encrypted form.
- Digital evidence: They preserve data securely for forensic investigations.
- Segmented storage: They may be one part of a multi-file series (e.g., S01, S02) that together form a full disk image.
Based on information from FilExt.com, these files are not meant to be opened with routine applications like media players or text editors, making them ideal for secure data storage and forensic use.
Using the correct decryption and analysis tools is key to accessing the stored information.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .s01 file?
An .s01 file is typically the first segment of an encrypted disk image created by AccessData forensic software. These files contain a secure, bit-by-bit copy of a hard drive or storage device used for digital investigations. They are usually part of a multi-file series (e.g., .s01, .s02, .s03) representing a single large volume.
How do I open an .s01 file?
You need specialized forensic software such as AccessData FTK Imager or Forensic Toolkit (FTK) to open these files. Because .s01 files are often encrypted, you will likely be prompted to enter a password or provide credentials to mount the image and view the file system inside.
Why do I see .s01, .s02, and .s03 files in the same folder?
This indicates a split disk image, where a large forensic file has been divided into smaller chunks for easier storage or transfer. To access the data, keep all segments in the same directory and open the first file (.s01) with your forensic tool; the software will automatically link the subsequent parts.
Can I convert an .s01 file to .E01 or raw .dd format?
Yes, you can use FTK Imager to load the encrypted .s01 image (provided you have the password) and then export it to other standard formats like EnCase (.E01) or Raw (.dd). This process is often done to make the evidence compatible with other analysis tools.
What is the MIME type for .s01 files?
These files typically utilize the generic MIME type application/octet-stream because they consist of encrypted binary data without a specific standard registration. For more details on how generic binary streams are handled, you can check mime-type.com.
Why can't I open .s01 files with 7-Zip or WinRAR?
While .s01 files are technically archives of disk data, they use a proprietary structure and encryption method specific to AccessData products. Standard compression tools like 7-Zip or WinRAR generally do not support this specific forensic format and will fail to extract the contents.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
