I have a large destination file which often needs to be updated from the data from other source files. Source files changes with external processes. There could be few source files changes out of the lot. (ex.. 3 out of 200) Changes in source files does not necessarily happens at the end of the file. How do I update the destination file from the source files without concating all of them?
Thanks.
