photoshop · HeyBraza shows you
could not complete your request because the scratch disk is full
HeyBraza points at edit > purge and the scratch-disk preference so photoshop gets room to breathe again.
'could not complete your request because the scratch disk is full' means photoshop ran out of the temporary working space it uses on your hard drive - usually because your startup disk is nearly full. clearing space and pointing photoshop at a roomier drive fixes it. here's how.
short answer
free several gb on your startup drive, then use edit > purge > all to dump cached history. to stop it happening again, add a second drive under preferences > scratch disks and restart - hold ctrl+alt (cmd+option on mac) while photoshop launches if it won't open at all.
or do it yourself
- 1free up disk space on your startup drive - empty the trash/recycle bin and clear downloads; photoshop needs several gb free to work.
- 2inside photoshop, go to edit > purge > all to dump cached history and clipboard data (this can't be undone, but frees space immediately).
- 3point photoshop at a drive with more room: edit > preferences > scratch disks (windows) or photoshop > settings > scratch disks (mac), tick a second drive, and restart photoshop.
- 4if photoshop won't even open, hold ctrl+alt (windows) or cmd+option (mac) right as it launches to open the scratch disk preferences before it loads.
- 5clear the temp files: search your drive for photoshop temp files (named 'pst…') and delete any left over from a crash.
