Is it possible to change the location of Photoshop's scratch disk file?

Question

By default, scratch disks feature use "root directory" of selected partition/disk. For example:

X:\Photoshop Temp1664856906880

As I understand, these scratch disk files should be deleted after photoshop is closed, but this is not my case. Now I can see another two files present.

My question is, whether is it possible to change location of these files to some folder. E.g:

X:\scratch\Photoshop Temp1664856906880

In Photoshop CS6 there is no advanced settings under Edit > Preferences > Performance... where I could specify the path.

Solution 1

It may be keeping scratch files of recently opened documents.

It is definitely preferable to not have Photoshop using your boot drive as a scratch disk anyway, but you cannot specify any sub-folder, as far as I'm aware.

Solution 2

You won't be able to control the location of the temporary files beyond which disks they will exist on.

1. Click Edit select to Preferences, and then click Performance.
2. Select the check box next to the scratch disk you want to use or clear the check box to remove it.

I couldn't find a screenshot of the Windows version, the instructions are the same, since the physical location on the drive can't be changed on both OS X and Windows.

Photoshop's inability to delete the files are likely connected user's permissions. The solution to your problem is to use a different disk other then your system disk.

Solution 3

In Newer Versions You can Hold [CTRL]+[ALT] keys When click to start Photoshop and then see windows to set scratch disk.

Can you use an NTFS junction? Create one that points the scratch directory to any other drive and folder you like.

Sorry, I edited the question. C drive was a bad example.
