# Loading Troubleshooting

> Common issues when loading DICOM files

## Files Don't Appear

* Ensure files are valid DICOM format (`.dcm` extension or standard DICOM without extension).
* Non-DICOM files (JPEG, PNG, TIFF) are not supported.

## Black Screen After Loading

* Check that your browser supports **WebGL2** (Chrome, Edge, or Firefox).
* Enable hardware acceleration in browser settings.
* Update your GPU drivers.

## Slow Loading

* Large datasets (500+ slices) may take longer. Check the progress bar.
* Ensure you have at least **4 GB RAM** available.
* Close other browser tabs to free memory.

## Only One Series Detected

* Make sure all series are in the **same folder** or subfolders.
* Check that each series has a distinct Series Instance UID in the DICOM headers.

## Browser Crashes

* Very large datasets may exceed browser memory limits.
* Try loading fewer slices or a single series.
* Use Chrome (it has better memory management).
