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.

As you know, ArduoFileSplitter is a freeware software born to split big file into smaller ones.

To split a big file into more little chunks can be useful to:

• save the file into multiple media
• send a big file to a friend  via multiple email  with little attachment
• share a file into p2p channels

In the previous tutorial we explained how to split a big file into some little pieces.

Usually the original file, splitted into lot of pieces, arrive at destination. The recipient receive the files and ans "how can I merge this chunks to rebuild the original file?"

The question is licit, and in this tutorial we will teach you how to do this.

First of all download and install ArduoFileSplitter. If you find some problems during installation, please contact us.

All the file chunks have to be placed in the same folder. In this example we have a file splitted into 44 pieces, placed into

"C:\test\" folder. A folder is equivalent to each othes, were the pieces are placed is not the matter.

The first step is to open ArduoFileSplitter and select the "Merge" tab. The windows should be some like this:

Now we have to choose the input folder (where the pieces are) and the output folder (where the rebuild file will be placed).

We choose "C:\test" for input folder and "C:\test" as output folder.

Now we have to click into merge button to rebuild the file.

The rebuilding process can take some time depending on the files size. The progress bar tell us the process state.

When the work end you will find the rebuilt file into the choosed folder.

Note:

ArduoFile splitte generate a md5 checksum file during the splitting process. If it is present in the input folder with the pieces,

every file will be checked. If someone had been corrupted the progam report it. Another check to the output file will be done.

Thoose check can be done before trying to rebuild the file through the "Check Hashes" section of this application.

First of all download and install ArduoFileSplitter. If you find some problems during installation, please contact us.

Suppose that we nee to split a big file called "bigfile.zip" into smaller pieces no more big than 100KB.

The first step is to open the application. To do thi start menu > Programs > ArduoFileSplitter > and click into ArduoFilesplitter icon. This may vary from pc to pc.

Only for who download the portable version:

If you have downloaded the portable version, you need to extract the executable file from the zip archive. You can use the freeware 7zip op winrar. After that you can run the application.

Once the application run you got a window like this:

Now we need to:

1. Select the big file
2. Select the output folder
3. Run the split process

Select the big file

click into the "Select File..." button. A Open File selector dialog will appear. Through this you can choose the desidred file, in this sample the "bigfilke.zip" on my pc.

Select the output folder and file size

The choosed file will be fragmented into smaller pieces and wiil be saved into a folder. So We choose the output folder clicking into "Select output folder". 

We have to say how much bigger must be each cunk! So we put 100 into the site textbox and choose KB as measurement unit. If you wnato to use default sizes (i.e. CD ROM size or DVD Size) you find them as pre configured.

Select the big file

In the end, the easier task: we nee only to click the "Split" file. The process could take some minute, but you can check the state of the work through the progress bar.

Wen the progress finished, a popup alert you.

So we can open the selected folder:

This is the foldere used in my example, there is:

1. the original file
2. A set of file of 100 KB
3. The checksum file

The original file has been splitted into 16 pieces each of 100KB and a md5 checksum file has been product.

This file i very important beacuse contains a md5 checksum for each chunk and the checksum for the whole file. When you will send thoose chunks to someone, it could happen that some chunk will be corrupted during internet transfert. So the receiver ca check the integrity of each file with ArduoFileSplitter. If some chunk is not good, it ca be re sended. After the whole file have been rebuild with ArduoFileSplitter, you can check the integrity of the whole file. Now if there are an error,it dependes only by the receiver, because each cunks was good. You can discover how to rebuild a file, given a set of chunk, in the next tutorial.
