Tamara:
In your first post in another thread, you said:
So I looked in the help menu to try to delete the user. It said to turn off filevault. I tried and was told I did not have enough diskspace.
Have you been able to do anything about turning FileWault off? I suspect that you were not able to, since FileVault saves your User Folder in a sparseimage which occupies as much space as your Users Folder. In order to be able to turn FileVault off, you need that much space more.
This article gives you a bit more information about the issue.
Buying an external HDD is a good move. Actually that would have been my first recommendation. I hope that you bought a firewire external HDD, as you cannot make a bootable clone on a USB device. So, go ahead and clone your entire internal HDD to the external Firewire HDD using
SuperDuper. SD will make a bootable clone from which you will later boot your computer.
(The . in front of your user name indicates it is a hidden file. It might be that your Home Folder was renamed, with a . in front of it. You can try downloading
Wizzard and see if it shows your hidden folder. Note: This is a parenthesis; I suggest backing up and disabling FileVault first).
Post back and let me know how it is going, and we will see what comes next.
Good luck.
