View Full Version : Swap File

03-29-2004, 02:07 PM

Does OSX automatically partition a swap file? My hard drive got down to about 100mb of free space, and I was having LOTS of problems. I when I checked partitions from the UNIX command line, there was no mention of a swap partition. I'm thinking the problems were coming from programs trying to use virtual memory, but there was none left to use.

Any thoughts?

Swap files are generated and stored in /var/vm/ . That would be the root of your boot partition. If you want them to be on another partition, you have to do that yourself via the command line or using a 3rd party application.

Hey Yellow-

Here's the partition table. I don't see any mounted on /var/

Will this table even show the swap partition?

As I said in my last post, there is no "swap partition" unless you created one yourself. By default, all swap files are stored in /var/vm, /var is part of the root (boot) partition.

ls -laF /var/vm

I should note also, if you reboot your computer, the swap files will be removed and you should regain your missing disk space. If you're still short, you should try something like OmniDiskSweeper to help find what is sucking up your disk space.
