photoshop problems - scratch disk full

The Scratch Disk Full error happens if your MacBook Pro internal storage has very little space available. The first thing to do is always to try and move or delete enough files to free up at least 50GB of storage, and the more the better.

It happens because every time you open a document in Photoshop, a temporary file is created that stores working data and undo steps. If your computer’s internal storage is running low on free space, there won’t be enough space to create those temporary files. Opening a very large Photoshop document may require more than 100GB of scratch space. You can also plug in external storage with lots of room on it, and assign it as a scratch disk in Photoshop preferences.

Try to free up your disc by deleting the temp files:

1. Press the Windows Button + R to open the "Run" dialog box.
2. Enter this text: %temp%
3. Click "OK." This will open your temp folder.
4. Press Ctrl + A to select all.
5. Press "Delete" on your keyboard and click "Yes" to confirm.
6. All temporary files will now be deleted.
   
   Also you can delete your App Data Cash to free up your disc

For one thing, you probably need to free-up some hard disk space.

• Move data and work files to external drives.
• Uninstall non-essential software.
