[CP2K-user] the specified OLD file cannot be opened.

[Young In Jhon]

If I add ext_restart shown below for restart and run the input file, the 
following error message appears.

&EXT_RESTART
  EXTERNAL_FILE abc-1.restart  #  Needs to match project name above
 &END

-------------------------------------------------------------

The specified OLD file <abc-1.restart  #  Needs to match project *
 *  \___/     name above> cannot be opened.  

-------------------------------------------------------------
abc-1.restart file is located in the same directory and my cp2k version is 
6.10.
It is difficult to know what's the problem with it.

Restart is a basic operation and its failure is embarrassing.
What things should cause it? What's the meaning of "OLD" file at the error 
message?

Thanks.
 Luke
