I can't delete old (os9) system files !!

I am on osx. (one system only)
I did put in the trash my old system files that I had keep in backup (on an external drive) when I have swith to mac osx... you know... just in case...

Now that I don't need them anymore, I have put these files in the trash. They are still there because every time I empty the trash, everything delete but these files... probably because they are seen as system files...

HOW CAN I DELETE THEM ??

PS : And by the way, on osx, is there a way to acurate the speed of the drive. On os9 we were doing scan disk and optimising disk... Sometihing like this on osx ??

Be careful when deleting system files. are you running panther?..so i assume that you dont need to run classic?.my friend deleted and moved around OS9 system files and is mac went crazy.ha,ha its funny when i think about it now :headphone

yes, i do have only one system running, tis osx 10.3
I do not have a second system (os9). I just had kept my old backup system os9 files.

Somebody ca help me please?
How can I delete these files ??

What is the message you get when you try to delete them? If the files are locked you will need to unlock them.

the message I get is :
The operation cannot be completed because you do not have sufficient privileges for some of the items.
(i am the only user of this machine by the way, admin.)

Just had a thought: Try this Force Empty Trash

thanks for the link...
I just tried this free software. Did'nt worked !!
Probably because the files came from my external drive...&?%$#!

An other idea someone ??

Try selecting Secure Empty trash, that sometimes works for me.

If not,create a root account (boot from the CD, create a new account from the Finder Menu when it gets to the first installation screen, it is the same area where you change the account password and I believe it is listed as such in the finder Menu). The User Name MUST be root, the password can be whatever you want. When you are done, log into the new root account and empty the trash. Logout, log back into your profile and live happily ever after.

Be VERY careful in the root account as your can screw up you Mac BADLY from there.

ish,,, look complicated.
Thanks I will this one...
