excellent recovering Status - files have file-size larger 0 - pdf not openable - tried with various pdf Readers / writers. (win8.1-64b). see enclosed example. who can help?
Perhaps nobody. The file does not have a PDF file header, nor any header that I can recognise. Presumably the data clusters have been overwritten at some time (a file state of excellent means that no live file is using the clusters at this time).
It's possible that a deep scan might help, look for .pdf files of the approx size. However a deep scan will not recover fragmented files so possible yes, probable not really.
