Hi Raghu, Can you pl explain what curFile and backupFile refer to in this context? Are you referring to the block data file and the metafile?

Another approach I am thinking of is to check curFile.lastModified() and backupFile.lastModified(). As long as these two are different, we could assume they are different files. This is simpler than trying to lock the files. Raghu.
