    scratch disks

    Can someone please talk me through the subject of Scratch Disks (I am using Painter X, and Mac 10.5.4)?-- After finding Painter (which I have only just begun to use) going slower and slower on my (low-end) Macbook, I found Jin's article which speaks of adding an external hard drive for your scratch disk. What exactly is a scratch disk? What size do you need? Does it get confused with the "time machine" function on Leopard? Would you also use such a thing to store ALL Corel files, to save memory on the computer's hard disk, and if so, how would you set that up?

    Re: scratch disks

    I'm sure someone will give you a better, and more technical,  explanation once they see this post torraccia but for now here is what I learned the other day when a friend heard me complaing about the way my PC worked slowly in painter, occasionally told me I did not have enough memory to complete a process and even shut the programme down as it encountered an 'error'

    I was told to open painterX go to edit, preferences  and then memory&scratch.

    The 'memory usage was set to use 80% of available memory and then the was set to use the largest section of my PC's partition which for me was drive D as drive C (which it had been set to) was only a quarter of the size of this drive.

    I hope this helps.

    I was told that the scratch disc is rather like having a sketch pad made of acetates where you draw every section of the image on a seperate page and therefore need lots and lots of pages for each image before you reach your final result where you can flatten them and put them all onto just one sheet of paper. That made some sense to this non technical brain of mine.

    I have had no problems since changing the scratch disc setting and the whole thing seems to work smoother and swifter.

    Hi,

    Again, since the subject of this thread is related to understanding and using Corel Painter in general, not to a technical issue or bug requiring help from the Corel Painter developers, I've moved it from the Got a Question? forum to the appropriate forum, Corel Painter X.

    Thank you for demystifying this for me, Squirrel! I think I am set up and ready to roll.

    Re: scratch disks

    It's me again....do you STORE finished Painter files on this scratch disk, too, or is it mostly for rough drafts? What is it that uses up so much memory in the computer, the fat preparatory files, or the final product? Would it be reasonable to keep everything pertaining to Painter in this one place, and if so, how would you set that up?

    Torraccia,

    The scratch disk is not used by the artist to store files.

    It's virtual memory used by the program when there's not enough RAM to perform an operation. By default, the scratch disk used by Corel Painter is on the hard drive where the program is installed, but it can be changed by the user to be on an external hard drive or other local drive. 

    If you don't want it on the hard drive, to change the drive for your scratch disk go to Edit > Preferences > Memory & Scratch (Windows) or Painter X > Preferences > Memory & Scratch (Mac).

    Re: scratch disks

    Jen, I'm not yet too fluent in computerspeak, so I guess I haven't been clear. May I try again? My Painter program was going very, very slowly and crashing alot, and thanks to your help sheet on keeping it running smoothly, I went out and bought an external hard disk, 300 g. I now plug this into a port on my laptop (not much RAM!) any time I am using Painter, and as everything is going much better now, I assume it is absorbing the big memory-gobblers. What I don't understand is this: once a file is saved, even" iterative save", is it saved on the scratch disk, or the internal hard drive? Would it not be smart to set things up so that Painter files ARE saved on this external hard disk, freeing up my limited internal memory for things like photos? I am not sure if "scratch disk" is special terminology relating only to Painter, or if this entire external disk, which I have told the computer is named "scratch disk", can also be put to use for other things, like storing my finished Painter files. You are obviously a very smart computer wizzard--what do you say?

    Hi Torraccia,

    The scratch disk is virtual memory used by the program when there's not enough RAM (random access memory) to perform an operation.


    What I don't understand is this: once a file is saved, even" iterative save", is it saved on the scratch disk, or the internal hard drive?


    Again, Painter files are not stored in the scratch disk. Similar to system RAM, the scratch disk is temporary, used to "remember" things while we work so Painter can perform operations we ask the program to perform or that are automatically performed when the program is being used. The scratch disk is virtual memory used when we run out of system RAM, to allow us to continue working.

    Would it not be smart to set things up so that Painter files ARE saved on this external hard disk, freeing up my limited internal memory for things like photos?

    Memory (system RAM and virtual memory, or scratch disk) and hard drive space are two different things.

    If you save files to your external hard drive or to a CD or DVD rather than to the computer's hard drive you will save space on your computer's hard drive.


    I am not sure if "scratch disk" is special terminology relating only to Painter,....

    Scratch disk is not terminology related only to Corel Painter. It's used for other programs as well.


    ,,,, or if this entire external disk, which I have told the computer is named "scratch disk", can also be put to use for other things, like storing my finished Painter files.

    Others may share how they save their files or where they back them up. Here's how I do it:

    I've specified my external hard drive, also 300 GB, for the Painter IX.5 and Painter X.1 scratch disk, and also use my external hard drive as a place to back up files. 

    You are obviously a very smart computer wizzard--what do you say?


    First, thanks, but I would not call myself a computer wizard, not by a long shot. There are many who are much more techie oriented than I am and I can only share what I've learned from years of using Corel Painter and other graphics programs.

    As outlined in my Sticky thread at Conceptart.org's Painter forum, use File > Save As for the first save, then use File > Iterative Save for following saves and Painter will automatically save the file to the same location where you saved the first time using File > Save As and add a series of numbers at the end of the file name you gave it when saving the first time. The series of files will look something like this:

    • my_painting.rif (first save using File > Save As)
    • my_painting_001.rif (second save using File > Iterative Save)
    • my_painting_002.rif (third save using File > Iterative Save)
    • my_painting_003.rif (fourth save using File > Iterative Save)
    • .... and so on. 

    When I'm working on a project, I save the file this way, first using File > Sava As, then using File > Iterative Save every few minutes or when I make a significant change to the image (whichever comes first). Then I have a series of versions of the same image as it is developed. If anything goes wrong, I don't lose much work as I can always go back to a previously saved version and continue working.

    In order to keep things organized, I usually create a new folder somewhere on my computer's hard drive (or on my external hard drive). I create the new folder somewhere outside of both the Corel Painter application/program folder and the Corel Painter User folder. Then I use that folder to save all of the files related to the specific project, including notes when I want to remember the process in order to explain it to others or to use when writing a tutorial. Sometimes I take screen prints of dialog boxes as an easy way to remember the settings I used, then save those screen prints in the same folder. Examples might be settings I used in the Effects > Surface Control > Apply Surface Texture dialog box, or settings used in the Effects > Surface Control > Woodcut dialog box.

     

    Hopefully, we've been able to give you enough information to make the difference between memory and space clear, and to help you understand what a scratch disk is used for.
