start up disk is almost full

The startup disk is simply your internal hard disk.

Copy files to an external USB hard drive, then move the original files to the trash and empty.

i have the same problem ..

while i use only 7GB in my user account and and 5 GB in desktop

HD available space 5GB

how i can solve this problem ?

Hi,

you have to have a lot of files somewhere else on your disk. Desktop btw is a part of your user account. Have you stored files somewhere apart from your user folder?

Volker

Hi,

that is a lot "missing". Have you setup Bootcamp (for Windows boot)? Have you emptied your trash?

volker

i already emptied my trash , but boot camp i am not use windows so, why i use it

thank you , again

omar

If you look directly in Macintosh HD, are there any single big filesß If you have not set up Bootcamp, than it can not explain 90 GB missing :-/

i will think about it.

volker

Hi,

To help locate where large files are stored, please try "Grand Perspective" (Free).

This program will graphically show you where large files and small files are stored:
http://grandperspectiv.sourceforge.net/

thank you for this advice.

i take this program and i locate this file which is appear as tow large files.

Macintosh HD / private / var / log / system.log.1

after i remove it 100 GB available

thank you Volker Runkel for your efforts

thank you PockyRevolution for grand perspective .
you are the one how is slove my problem.

Omar,

a 100 GB system log file is not normal. Something must be producing many messages in your system.log - i recommend you monitor that file and if it grows again that fast, you should use console.app to see what produces these many system messages.
