About .dcx Files
DCX files are multipage image containers used mainly by ZSoft Paintbrush.
They store a series of bitmap images in one file. This makes them handy for applications like scanning or faxing where several pages need to be kept together.
- Main use: Multipage graphics handling via the image/x-dcx MIME type.
- Alternate purposes: Related to the PCX format as shown by the image/vnd.zbrush.pcx and image/x-pcx MIME types.
- Additional use: In some cases, DCX may act as a generic binary file (application/octet-stream), such as legacy Microsoft Word for DOS documents.

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 a DCX file?
A DCX file is a multi-page graphics file originally created by ZSoft for the PC Paintbrush program. It functions as a container that holds a sequence of PCX bitmap images, which made it popular for saving digital faxes and multi-page scanned documents in the 1990s.
How do I open a DCX file on Windows?
You can view DCX files using third-party image viewers such as IrfanView, XnView MP, or GIMP. Since Windows Photos does not natively support this legacy format, installing one of these lightweight graphic tools is the best solution.
Can I convert a DCX file to PDF?
Yes, converting DCX to PDF is highly recommended because both formats support multiple pages. You can use software like XnConvert or various online file converters to transform the bitmap sequence into a single portable document.
Why can't I open my DCX file in Photoshop?
Modern versions of Adobe Photoshop do not natively support the DCX format. To edit these files, you must first open them in a compatible viewer like IrfanView and save them as a TIFF or PSD file before importing them into Photoshop.
Is a DCX file always an image?
Not always; while usually an image, the .dcx extension was also occasionally used by legacy Microsoft Word for DOS for document files. If an image viewer cannot open the file, it might be an old text document that requires a specialized file converter.
What is the correct MIME type for DCX files?
The standard non-registered MIME type for these files is image/x-dcx. However, because the format is based on PCX, you may occasionally see systems identify it as image/x-pcx or image/vnd.zbrush.pcx. You can look up more details on mime-type.com.
How do I fix a corrupted DCX file?
If a DCX file fails to open, the header linking the internal PCX images may be damaged. You can sometimes recover the data by using a hex editor to extract the individual PCX streams or by using robust conversion tools like ImageMagick to attempt a forced conversion.
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.
