How to "Compare File"?

[hstijnen]

Hi,

How can I compare files on disk? I can't find in the CBuilder file routines.

Thanks

ASAIK, niether C++ nor Builder have a pre-built routine to compare files. You could write your own and compare the files byte by byte.

I suggested myself to use a system command, but I don't know how to catch the result.

If everything had a precoded function to accomplish every task then why are we struggling so hard to learn these arcane arts.

Actually i think that it might be a bigger programming job to interpete the output of the "FC.EXE" program.

It's really quite simple:
1: Open the two files.
2: Check file sizes/dates and such.
3: Load all or a portion of both into memory depending on size.
4: do a byte-wise compare.
5: If no difference exist repeat 3 & 4 untill the datas are all compared.

Now You know!!!
