vi/vim FAQ: I keep getting these vim swap/temporary/backup files in my current directory, the ones with the tilde (~) character at the end of the filename; how do I get these swap/temporary files to go into another directory?
A vim swap file (at least on Mac OS X) is named with a ".swp" file extension, and seems to exist as long as you are editing a file in vim. The vim backup/tilde file is the filename that has a "~" character appended to the end of it, and when these are left in your current directory, they're pretty annoying. You can tell vi/vim to place both of these temporary files in another directory, as shown here.
Moving vi/vim temporary/swap/tilde files on Mac OS X
Using vi and vim on my Mac OS X systems, I tell vim where to place the backup and swap files using the commands shown here:
" tell vim to keep a backup file set backup " tell vim where to put its backup files set backupdir=/private/tmp " tell vim where to put swap files set dir=/private/tmp
I just place these commands in the
.vimrc file in my home directory, and I no longer get all those junky vi/vim swap/tilde files in my current working directory. If you're using an older version of vi, you should place these commands in a file named
.exrc in your home directory.
This same approach should work just fine on other Unix systems as well, though you may want to change that directory to just
/tmp. That "directory" didn't work for me on Mac OS X, probably because
/tmp on Mac OS X systems is actually a symbolic link to the
vi/vim temporary/swap/tilde files on MS Windows
I don't have a Windows system I can test on at the moment, but the approach should be similar; just tell vi/vim where to place these backup/temporary/tilde files. Something like this should work, assuming you have a C:\Temp directory.
" tell vim to keep a backup file set backup " tell vim where to put its backup files set backupdir=C:\\Temp " tell vim where to put swap files set dir=C:\\Temp
I'm guessing that you need two backslashes there, though I could be wrong. If anyone knows for sure, I'd appreciate you letting me know in a comment below.

I hope this vi/vim tip on moving your vi and vim temporary backup and swap files to another directory is helpful.
