Arduo File Splitter is a free tool born to split big files into littler pieces. We spoke about the standart feature of this application in previous tutorial:

In this brief tutorial we teach how to compare two files to check if they are equal. Some time it  could be usefull.

For example, after you copied a file from an external disk to your pc, you could ask if the  copied file has any errors. Of course, if the two files are "equal" there isn't error:you are sure that the copied file is fully functional.

But wat means, in this context, "equals"? Arduo File splitter calculate an md5 file for each files and compare it. Obviously, same files have same checksum. So

if they are different, some error occour during the copy.

To compare the file, you need to download and install ArduoFileSplitter, and open it. After that you have to select the "Compare" tab. You should see something like the window belove:

Now Youo only need to choose the files and check "Compare MD5 hash". Then click "Compare". After the hashes computation, the result will appear on the form.

Note:

The md5 hashes computation is the safer method to compare files. Others tools like this check  the file length to compare two files. This is obviously  unsafe because different  files can have the same length. Just think to take a text file and replace all the "a" letters with "b". The resulting file has the same length than the previous one, but the content is vey different.

To provide same feature of other tools we add the length comparing method. This is more quick, but very unsafe. If you need to check little fle we reccomand to use always the md5 method.
