Dear Sir / Madam,
I was installed Dspace 1.8.0 using ubuntu desktop. it was functioning best
but unfortunately Hard Disk Media is crashed and i dont have any backup,
therefore i have submitted the same to data recovery as around 2000 items
with their PDF as bitstream were there.
Now data recovery company is asking for file extensions of the files to be
recovered which will enable me to restore the complete dspace including
Database in postgres, Dspace, Customized layout of JSPUI. Here all the
bitstreams are .pdf only.
I hope you will help me in this.
Mr. Shivraj Thorat

The files in assetstore don't have any extensions. Here's how the
assetstore is structured (especially see the example):
If you can recover the original filename, it's easy to restore the
directory hierarchy based on the first digits of the bitstream name.
If you can't recover the filename, it's still possible to reconstruct
the filename from data in the database, but it will require some work.
Basically you need to run md5sums on all the recovered bitstreams,
then look up the MD5 values in the checksum column of the bitstream
table and rename them to the value in the internal_id column of the
same row. Then you can proceed as above to restore the directory
