Despraying BLOB Data

The DFUplus.exe program also allows you to despray BLOB files from the HPCC Systems platform, splitting them back into the separate files they originated from. The key to making a despray operation write BLOBs to separate files is the use of the splitprefix=Filename,Filesize option. For example, the following command line desprays all the BLOB data to the c:\import\despray directory of the 10.150.51.26 machine from the single logical file named LE::imagedb:

C:\>dfuplus action=despray dstip=10.150.51.26 dstfile=c:\import\despray\*.* 
            srcname=LE::imagedb PREFIX=FILENAME,FILESIZE nosplit=1

Once this command has executed, you should have the same set of files that were originally sprayed, recreated in a separate directory.
