There’s not enough space on the disk to cache DRE speaks

This DRE warning appears when it can’t save DRE speaks to its local cache:

There's not enough space on the disk to cache DRE speaks

You have 2 options to deal with this issue:

Clean up your drive

Delete unused files, apps on the drive that DRE uses for its local cache. Ideally you need 2GB or more of free space. The DRE warning will mention the drive that needs more space.

Use Windows’ Disk Cleanup to gain available space. Search for this tool in Windows Start and choose the drive to clean.

Move DRE cache folder

If you simply cannot make more space available on your drive, you can instead move the DRE cache folder to another drive. Here’s how:

Open DRE
Go to Settings
On the General tab, look for the Folders section
Click the Move Documents Folder Browse button
Find another drive with sufficient space (open the This PC and locate another drive)
Create a folder somewhere and call it “DRE Docs” or similar and hit OK
DRE will now move the cache over to the other drive’s location
Restart DRE for it to take full effect
