Hi,
If you used the Ibexfarm interface to delete those two files, they were deleted using Perl’s unlink function, so the OS no longer maintains a copy of the files. In that case, you might want to consider using some recovery tools to try and retrieve your files (eg. PhotoRect is a free, cross-platform software that I’ve used with success in the past) — do it as soon as you can though, since when the OS reallocates memory used by the deleted files those can no longer be recovered
If you deleted them manually using a file browser, maybe the OS sent copies in a recycle bin of some sort
