This postscript driver is trying to place the file in:
Note: i don't know why it's trying to place it in your temp folder - that's the fault of the print driver.
But the process, that is doing the printing, has been marked as Integrity Level: Low. This means that the process is very limited in what it is allowed to do on the computer.
One of these limitations is only being allowed to write to file system locations that are set to allow Integrity Level: Low writes (i.e.
c:\Users\Jerry\temp does not allow low integrity writes). A default install of Windows Vista/7 marks only two folders with the Low Mandatory Integrity Level:
%LOCALAPPDATA%\Microsoft\Windows\Temporary Internet Files\Low
These are the only two places that a "Low" integrity process are allowed to write.
If a process gets "access denied" while trying to save a file: Windows will silently try the save again, but this time redirected to a location that allows the write. (Note: This is a compatibility hack for applications that were written before Low Integrity existed)
The same effect happens if you try to write to a location that requires administrator access, but you're only a standard user. e.g. if i try to save a file to:
The write will fail, and Windows will silently try the save again, but this time to:
Later, if you try to open
Windows will silently redirect to the copy in the Virtual Store.
This is all done so that applications, which incorrectly assume that all users are administrators, will still function when the user is really a standard user.
Note: On Windows XP these applications would fail, and usually horribly, when they were not allowed to save wherever they want. Microsoft added, with Windows Vista, this huge compatibility infrastructure to allow these rogue applications to work as standard user.
Next question: why some folders are hidden when you unhide them.
Folders having the Read Only & System attributes are understood to be special system folders. In order to see them, you have to change your Windows Explorer preferences, and turn off:
- Hide protected operating system files (Recommended)
Temporary Internet Files folder is marked as hidden, so you'd also have to turn off the option:
- Do not show hidden files and folders
You might be wondering how Internet Explorer can download files; when it's not allowed to write to any location except the Mandatory Integrity Level: Low location.
The answer is that once the file is downloaded, the process running the tab communicates back to the Internet Explorer controller host, and asks it to move the file to your requested location. The IE controller process runs with your (standard user) privelages - while each tab runs in a Low Integrity process.
i think if you print something from Notepad, or Word, or some other "regular" integrity level process, that the save will work fine...to the temp folder.
i'm surprised it doesn't ask you where you want to save the file.
