I want to build a 3D database of molecules for virtual screening and for this i have selected the ZINC database as an input. Previously i have built databases such as ASINEX where the input file was in .SDF format but ZINC database has a SDF.CSH format (eg:filename.sdf.csh). the file opened through wordpad in windows XP platform looks like this

wget --base=http://zinc8.docking.org/subset1/12/ -i - <<+
12_p0.0.sdf.gz
12_p0.1.sdf.gz
12_p0.2.sdf.gz
12_p1.0.sdf.gz
+

It looks like it contains several files in a compressed format

what is the procedure to convert  or otherwise extract the information from this SDF.CSH file to make it as .SDF?

I am using DS2.0  in a windows XP platform.
