Occasionally a file may appear on your Palmtop as a result of some unknown glitch. The file name may contain some unprintable characters that prevent it from being erased by Filer.
To get rid of such files start Filer and point at the drive and directory that contains the pesky, undeletable file. Then go to the DOS prompt by pressing [MENU] Options DOS. Type the command ATTRIB, at the DOS prompt and press the Enter key. (Note the comma after the word ATTRIB. The comma is a shortcut that saves you from typing -A -H -R -S.) When you press Enter all the attributes of every file in the directory will be removed.
Then type the command DEL *.* /P and press Enter. The DEL command will prompt you for a 'Y' or 'N' response for each of the files in the directory. Press until you come to the undeletable file and then press Y and the file will be deleted.
To make sure there are no other problems with your disk, use the CHKDSK /F command. If you get a message that some damaged files were found, answer Y to the question about 'fixing' them.
