Why some files cannot delete?  If I delete, will say cannot read from the source file or disk?  Somebody can help me.  Thanks.

What is the file name, where is that file location? it looks like you  delete a file that already gone.

你check你既regional options既standard format係用咩language. 如果之前你係用英文,而那時你save個file,咁依架你換佐另一個language,咁呢個file就唔delete得. 你要換返原本即setting先可以delete個file啦.

try delete the files in safe mode

如果不能delete,可能正在使用中,如下圖,可以用安全模式,開機按F8,後刪除

I already try the safe mode.  It cannot delete.

the file in my c:\documents and settings\my documents\my ebooks.  the file name is
CAGD898F and CAI3SLE5.  the file cannot rename, move, and delete.  thanks.

Maybe you can try this:

1.  Go to Start_Run and type CMD in the box. Enter.
2. Change directories to get to the parent folder of the renegade directory.
    Type cd..   to move up one level.
    Type cd yourfolderpath    to move to a specific folder within the drive you are currently in.
3. Display the contents of the directory with DOS 8.3 naming convention (short names).
    Type dir /x /a
4. Find your bad directory and rename it to less than 8 letters.
    Type ren currentfoldername newfoldername

5. Close the Command Line Editor.
6. Open Explorer and try to delete the folder you just renamed.
OR
5. Delete the file in Command Line Editor.
    Type del newfoldername

Hopefully it´ll work for you.
