Increasing Scratch Disk Capacity Limitation?

    The size of my primary scratch disk is 120 gig ---- however when photoshop
    scratch memory, applied to this drive exceeds 2 gigs, photoshop advises
    primary scratch disk memory is maxed out and recommends that I need to
    remove unneeded files to provide more scratch disk capacity. Win2k file
    manager shows that I have 111 gigs of remaining space on this drive when
    this occurrs.

    I'm using Photoshop version 4.

    How can I increase this apparent 2 gig memory limit on my scratch disk?

    TIA for any suggestions.

    I know that the FAT(32) file system is limited to individual file sizes
    of 2GB. A disk partition and volumes can be bigger but a single file
    cannot. If you can convert your disk to NTFS then that should remove
    this limitation. If you already have an NTFS disk volume then maybe it's
    PS limiting the file size.

  3. I've always thought that FAT32 support file sizes up to 4 GB. FAT16
    has a file size limitation of 2 GB, as far as I know.

    Photoshop can't use more than 2 GB RAM and that's probably the reason
    why it can't write a scratch file larger than 2 GB either. You won't
    get a larger scratch file size even if you tell Photoshop to use a
    NTFS disk as the scratch disk. When it reaches 2 GB, it creates a new
    scratch file, even if the scratch disk is NTFS.

    1) More scratch disks.

    2) Photoshop CS.

    All of my drives are NTFS and I have both a primary and secondary scratch
    disk specified, both with lots of excess available space. When the primary
    disk scratch file reaches 2 GB, a new/second temp scratch file is
    established in the secondary drive ---- and when it caps out at 2 GB,
    photoshop issues the error message that the secondary scratch disk is
    filled-up.

    I assume that you mean that Photoshop creates a new scratch file in the
    secondary scratch disk, when the primary disk file reaches 2 GB ---- not a
    third new temp file in the secondary, when the second temp file maxes out at
    2 GB.

    I'm only encountering this problem while working on a special
    application ---- so my question is more academic than representing a common
    problem. However, thanks to all for your comments and suggestions.

    You REALLY need a newer version of Photoshop.....

    The limit in Photoshop 7 is about 4 Exabytes of scratch, and the limit
    in Photoshop CS is about 64 Exabytes.

  7. No, I wrote that. :)
    I haven't experimented with a secondary scratch disk because I don't
    need it at the moment. I have only 1 primary scratch disk defined in
    Photoshop and when the size of the scratch file reaches 2 GB, Photoshop
    creates a new file on the same drive, no matter if the scratch disk is
    FAT32 or NTFS. I guess it keeps doing that until the drive is full, but
    I have never experienced that.
