[G14_run] [EXTERNAL] Re: Files at /cache

[Tsuneo Kageya]

Ciao Alessandra,

 thank you for the more response.

(2) Here is an example of file which is both at /cache and tape and we can get such a file from the tape.

ok, fine. It looks like the files on tape are more recent than those in
disk, doesn't it? So probably they were the output of the cooking.

      Ciao, Tsuneo Kageya.
