Pytivo transfer to Premiere disappeared, why?

I am using Pytivo with HP WHS and Premiere. I was able to xfr a 3GB file from the WHS to the Premiere a few days ago.

The strangest thing is that the file seems to have disappeared from the Premiere. My wife swears she did not delete the file.

Any idea on what could have happened here? I wanted to keep the file on the Premiere until I deleted it manually.

Please let me know. Thanks.
