It always takes me a few tries to create junctions for some reason.

Try checking out this post and see if it helps clarify some things:
https://stackoverflow.com/questions/12037723/windows-7-symbolic-link-cannot-create-a-file-when-that-file-already-exists

Typically that error occurs when the target folder already exists. If you want to have the target folder to be D:\ZBrush\QuickSave for example, make sure the folder “QuickSave” Doesn’t already exist. Try that and let me know if you still have problems.

Got any other suggestions?

Hi Pete,
Okay, I got a couple ideas.
First, let’s make sure you’re running the Command Prompt as an Admin, which is different than just running the command prompt with a Windows admin user account. In Windows 8.1 when you right click the start button, there are two options for the Command Prompt, one has (admin) after it, that’s the one to use. If you’re using a different version of Windows let me know and I can try and help ya out, if that might be the issue.
Second, I reviewed some mklink information and it sounds like it might throw that error if the target folder already exists. I.e. in my example if “D:\Users\Public\Documents\ZBrushData” already exists, try deleting it (make sure to back anything up in there if necessary) and trying the mklink command again. If you never created the target folder, I would also try creating it first, just to see if that works.
Third, if neither of those ideas work, you can try creating a “symbolic link” instead. This may work better with Windows 10 anyway, if that’s your OS (I’m currently still using Windows 8.1). To create a symbolic link, you just change the option parameter of the mklink command. Instead of using [mklink /J] you’d use [mklink /D], so the command I would use for my personal system would look like:
mklink /D “C:\Users\Public\Documents\ZBrushData\” “D:\Users\Public\Documents\ZBrushData”
the only difference being the /D instead of /J. Directory symbolic links and junctions are similar, the biggest difference is symbolic links can work with mapped network drives.
Another thing you could try, if you’re copying and pasting the command, is paste it into notepad first. Then copy it again out of notepad, before pasting it into your command prompt. That should hopefully rule out any weird character encoding strangeness, just in case.
Hopefully that will help! Now I need to go pour a drink to cheers with ya :-).

Hi Landon, thanks for responding! There seem to be no shortcut icons on either of the folders you mentioned, and as for what I typed in I simply cut and pasted the command from this page. Maybe I should just do it with the quicksave folder as that’s the main offender- even with quick saves limited to 10, it’s still 10.8gb! My System drive is only a 120gb SSD, so I set all my other programs to store/cache files on one of my other 1TB drives. But of course, ZBrush doesn’t want to let you do that for some reason…
Cheers,

Pete

Hi Pete,
I’m guessing you get that error when you submit the command to create the directory junction inside the DOS prompt?
My guess is, if you’ve tried it more than once, you might have already created it.
When I go to “C:\Users\Public\Documents” using File Explorer, it shows the ZBrushData folder icon with a shortcut arrow, instead of the usual plain folder icon, letting me know it’s a directory junction. What does yours look like?
If you’re only trying to change the QuickSave folder storage location, and not the entire ZBrushData folder, then check to see if it has the little shortcut arrow on the folder icon instead.
If neither of those folders have the shortcut arrow on the folder icon, can you paste the exact command you’re typing into the “Command Prompt” for me, here in a reply?

I’ve been trying this, but it says “cannot create a file when that file already exists”. Any ideas? Now I’m completely tortured. I cannot understand why pixologic made it so you have to mess about with dos commands just to change the goddamn quicksave folder anyway- that is just unacceptable.
Thanks for your tips though.
