what does putty's different text colors of files/folders mean & how to disable

[sunhux G]

Hi,

When I "ssh" into our Linux boxes using freeware putty,
when listing out files, some files are painted in red text,
some in blue text & white.

What does the color code mean & how can I change
them or disable them.  Blue is highly unreadable.

The very same putty ssh into Solaris & HP-UX boxes
doesn't give rise to these colors.


Thanks
U
