Pre-Upload Checklist

Before uploading your medical scans to 3DICOM, making sure you have a few things in order first will ensure a smooth upload process.

Refer to the expandable pre-upload checklist below to get started.

Check and prepare your files for upload.

Locate your DICOM files:

Find the folder that contains the .dcm DICOM files for your scan.

If you’re using a USB or CD-ROM/DVD, make sure it’s securely connected or inserted before browsing its contents.

Avoid Unsupported File Types:

Do not upload .zip, .iso, .exe, or any installer/viewer applications — they’re not compatible.

CD-ROM/DVD Users Only:

Ignore any .exe or auto-launch software/files — you only need the raw .dcm DICOM files.

Look for folders named DICOM, IMAGES, or something similar.

For best performance, copy the scan folder to your local drive before uploading.
