Convert DICOMDIR to another file type
To convert DICOMDIR directory files to another format, you need MicroDicom or other Database software.
Convert a file to DICOMDIR
To convert other file formats to the "Medical Imaging Directory" file type, you need software like MicroDicom or a similar tool.
About DICOMDIR files
The .dicomdir file is an essential index file used by the DICOM (Digital Imaging and Communications in Medicine) standard. It is typically found in the root directory of a CD, DVD, or USB drive given to a patient after an MRI, CT scan, or ultrasound. Specialized medical viewers are required to read these files. Popular software includes RadiAnt DICOM Viewer, MicroDicom, and Horos for macOS. You can learn more about the standard on its Wikipedia page. A major disadvantage of the .dicomdir format is that it confuses patients and non-medical professionals. The file itself contains no actual images. It is merely a routing database that points to deeply nested, cryptically named dcm image files. Standard web browsers and built-in OS image viewers completely fail to process it. You cannot natively view your health data without downloading specialized, often expensive or clunky third-party medical software. Because it is a text-based database rather than an image, converting a .dicomdir file typically means extracting its metadata to TXT, XML, or CSV. If your goal is to get JPG or PDF images of your scans, you must target the actual dcm files located in the disk's subfolders, not the .dicomdir file. The .dicomdir format is notoriously difficult to process because it relies on strict medical compliance rules and specialized encoding. Often, only a dedicated medical viewer can properly parse the patient hierarchy data. If our analysis detects a supported underlying structure, viewing or metadata extraction may still be possible without installing heavy medical suites.
Convert.Guru analyzes your DICOMDIR file, detects the exact format, and lets you read the text inside.
If you want to convert DICOMDIR file to JPG, DICOM, DCM, MP4, CSV, JSON, XML, YAML, YML, TOML, INI or CFG, you can use MicroDicom or similar software from the "Medical Imaging Index Database" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to DICOMDIR, try MicroDicom or another comparable tool in the "Medical Imaging Index Database" category.
The DICOMDIR Converter Story
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 DICOMDIR converter.
