About editing BAT files
I created a BAT file for a program called FSUM (It is a program for checksum).

In my BAT file, it contains:
fsum -md5 -r *.* >md5_checksum.txt

The above command will copy the output to a txt file. However if there's an existing file with the same name already, it will overwrite it without prompt.

How to prompt if the program is going to overwrite a file? Does anyone know any command which can do so?

Look at this link, it should give you some clues:

You might be able to do something like this:
fsum -md5 -r *.* >md5_%time%.txt

Its been a long time since I've done anything with DOS batch files. There are certainly others here who have more recent experience in this topic. Please correct me if I'm not correct.

Hi.
What does "%time%" in >md5_%time%.txt do?

Anyway, I tried it but the comptuter said "parameters are incorrect".

I read your suggested website before you told me, but in vain.

And since you said you don't use BAT for a long time, so did you find any other more powerful things to replace BAT?
If so, what are they and how good they are?
