I don't understand what you mean. "No two files should be unique" means literally that only *one* file is unique, the others are copies of each other. Do you mean that no two files should be the same? > Moreover > the filenames should also be unique every time I run the script.

Start a counter at 0, and every time you create a new file, name the file by that counter, then increase the counter by one. > Can this be done within few minutes of time.

I doubt it. 1000 files of 1GB each means you are writing 1TB of data to a HDD. The fastest HDDs can reach about 125 MB per second under ideal circumstances, so that will take at least 8 seconds per 1GB file or 8000 seconds in total. If you try to write them all in parallel, you'll probably just make the HDD waste time seeking backwards and forwards from one place to another. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
