Have you encountered a problem with a DCM file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a DCM file here. In the further part of this page we have added a list of programs that should open your DCM file. It is enough you choose a proper application for your operating system, download and install it.


DCM files are image files in the so-called DICOM format. The DICOM format (Digital Imaging and Communications in Medicine) is an open standard for the exchange of information in medicine. DICOM images are lossy or lossless in TIFF or JPEG format and are embedded in the DCM file.
In addition to images from, for example, MRI, ultrasound, X-ray and CT devices, the files may also contain segmentation, patient data, findings and image registrations. Also 3D data is possible. At the same time, the DICOM standard also represents the protocol standard that is implemented in almost every medical device for imaging and image processing procedures.
In addition, DICOM forms the basis for the PACS digital image archiving system in hospitals and clinics (Picture Archiving and Communication System). Other, often used extensions for dicom files are dic and dicom. Partially the ending is omitted altogether.

Programs which can open a DCM file

How to open a DCM file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the DCM file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a DCM file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support DCM files. At this point we are looking for disk space where the application was installed in and we can link it with a DCM file. Since then, our operating system will use the selected program to support all DCM files.

Other issues

Despite the described problem with DCM there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the DCM file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the DCM file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
