Large File Upload increases the size of files that can be uploaded to Castor via the 'Upload File' field - from 5MB to 2GB per file.
Currently, this premium feature can only be added to a study upon request - please contact the Castor team to find out more.
⚠️ Important Note on File Availability
Upgrading to the Large File Upload (up to 2 GB) changes how your files are stored. Once enabled, any previously uploaded files in the standard storage (up to 5 MB) will become temporarily unavailable.
Need your existing files moved?
We can easily migrate your old files to the new storage for you! Just submit a quick request to our support team, and we’ll handle the transfer.
