Customize Width of Column View in Finder

I entered your topic line in a Yahoo search bar, this is what I got:
How To Keep Finder’s Column View Width From Changing

Hope it works for you! Let us know.

 

With Snow Leopard its very easy... Just hold down the Alt Key and use your mouse to set the column width. Finder will then remember this as the default setting.

 

This works for Finder, but how about in applications? For instance, I can set the width of the left column (shortcuts, network, etc.) in Finder using Alt, but when I go to open a file via Illustrator, the first column is so narrow I can't read any items in full. And then, the file columns are narrow and never remember to open wide enough to show the file names. Can this be fixed?
