Found SD crad in new HTC One M9.

I received a factory sealed HTC One M9 the other day from Vodafone. When I opened the SD card slot drawer I found a old 8GB Micro SD card in it........

On the card are the following:

Folders: Android, ghost [inside: SystemLoggers.conf & SystraceEnabler.conf] & LOST.DIR.

Zip: OPJAIMG.zip & OPJAMFG.zip [inside: android-info.txt, dzdata_16g.hdr, dzdata_32g.hdr & dzdata_64g.hdr].

Other files: @@htcmfg_sfcdata.txt, @@file_crc.mfg, OPJAMFG.CRC, htc58diag, PTPTDIAG.nbh, sec.dat & @@station.txt

Any idea what they are used for????
