This tip will help resolve error messages E97, E483 and E485 encountered on machines running MS Windows. These errors relate to the creation of, or reading of temporary files. See :help E97, :help E483, :help E485. Also see Fix error E97 Cannot create diffs under Windows.
*e97* Can't create diffs blah blah *e485* Can't read file blah blah
I've experienced these errors when trying to use the diff commands, or any shell commands being called via the :! or :r! commands.
:r! sort blah blah blah % or :r! dir etc
To correct this problem you need to change your environment variable for $TMP or $TEMP. You can do this in a couple of different ways.
1. Use the Windows environment settings. Here is one method. - Right click "My Computer". - Choose "Properties". - Click the "Advanced" tab. - Click the "Environment Variables" button. - In the bottom window pane, scroll down to the TMP or TEMP variables and highlight them. - Then click the "Edit" button and change the path to the directory you want. 2. Use Vim – much better! - Add the following to your _vimrc file: let $TMP="c:/tmp"
In both cases, you need to create the directory (for example, C:\tmp), and you need read and write permission in that directory.
- This tip needs reworking. A reader could get the impression that the only cause for the specified errors is due to TMP.
- Add a brief explanation of what the environment variables do.
- Probably want reference to :help dos-temp-files. Any others?
- The title is not helpful because a reader would only search for this title if they already knew the cause of their problem.
It's probably better for tips to be formatted reasonably consistently. I wouldn't advocate overdoing this, but I don't see why this tip uses <tt>...</tt> for the tip text, while the others don't.
It uses <tt>...</tt> cuz the defualt is too hard to read and, I like it. The diff ain't that big of a deal.
