in thread how to extract original string from binary files?

Hi Swapnil,

For various reasons I think it's best to just continue working via this site, that way everyone can learn from this thread. I already mentioned two ways you can convert your binary data to a format you can post here, to add more examples to that list there's A simple hex dump in pure Perl and various Windows tools available.

However, posting your binary data here won't help much if we don't know what format the file is in - the file format is actually much more important than the binary data. I see you've tried to describe it in the root node, but it's difficult to read, try using <code> tags.

    Hi Haukex, 

    Please check the hex dump of binary.
