Quick summary

You need at least 500 MB of free space on your hard drive for Imagen to prepare your upload. Large RAW projects need more: about 20% of the project's size.

What causes this error

• Your hard drive is nearly full.
• Imagen needs temporary space to prepare photos for upload.
• Large caches or temporary files are taking up space.

How to fix this

Check how much space you have

• Mac: Go to Apple menu › System Settings › General › Storage.
• Windows: Open File Explorer, and select This PC.

Free up space

1. Empty the Trash (Mac) or Recycle Bin (Windows).
2. Delete files you don't need from your Downloads folder.
3. Clear the Camera Raw cache in Lightroom Classic. Go to Lightroom Classic › Settings › Performance (Mac) or Edit › Preferences › Performance (Windows), and click Purge Cache.
4. Delete old Lightroom Classic catalog backups you no longer need. They're .zip files in the Backups folder next to your catalog.
5. Remove apps you no longer use.
6. If you still don't have enough space, split the shoot into a few smaller projects.

Then try the upload again.
