Files disappearing suddenly, and others not allowing me to delete them.

Question

First of all, I have a Power PC G4 1.42 Ghz, 1GB DDR SDRAM. And, my problem is mainly that files are continuously disappearing from my finder and/or Desktop. Their names are there and when I try to click they simply vanish. At the same time that this began happening, whenever I created a file to the desktop I was unable to delete it. It also happens in the Finder, but not as often. I click to delete and I get this error: +The finder cannot complete the operation because some data in... could not be read or written. (Error code -36)+. It began sporadically, but now it´s happening continuously.
I create a New Folder, and the same thing happens. It just doesn´t appear.

Hi sergiocarlos, and a warm welcome to the forums!
Not certain, but this can fix myriad problems...
Safe Boot from the HD, (holding Shift key down at bootup), it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions.
In finder, select Go menu>Go to Folder, and go to "/volumes".
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1, and reboot.
