One thing that is guaranteed to irritate me is when I have to email a file to someone and the file is too big. What do you do then? Well, you could compress it or you could use one of file transferring 'TOP 11 Tools for Sending BIG Files' released 'TOP 11 Tools for Sending BIG Files' released Read More services such as Pando. But recently I discovered another possibility. Using the freeware program JR Split File, you can split the file up into little pieces – and then the person at the other end puts it all back together again.

JR Split File is a portable program 100 Portable Apps for your USB Stick (for Mac and Win) 100 Portable Apps for your USB Stick (for Mac and Win) Read More which means that it doesn’t need to be installed on the PC. It can easily be run off a USB stick if you happen to be on the go, using someone else’s computer. When you double-click the program, the following box comes up :

As you can see in the screenshot, you would first choose the large file to be split. You would also specify the folder to put the smaller pieces into. Next, you need to specify how big each piece should be (useful if an email program has a file size limit) and if you want the recipient of the file pieces to be able to put everything back together again, you need to make a “bat” file (the “bat” file is what reconstructs everything). Then press “split”.

The file pieces will be placed in the folder you specified and then you can email them to the intended recipient. You MUST also send them the “bat” file.

The other person then just needs to place all the pieces AND the “bat” file in the same folder (they don’t necessarily need to have this program). They then just double-click the “bat” file and right away, the file is reconstructed in full. But everything has to be in the same folder otherwise the re-construction won’t work.

It worked perfectly on a lot of files on my PC and seems to be a very easy solution for sending those huge files to people by email.

    It's also handy for breaking movies into 10-20 pieces and transfer them using one of the file transfer services.

    I've used this on and off for years, especially in the days of dialup and smaller HDs. It worked great, and the bat file only has a few lines, so it's easy to check if anyone is nervous about executing a bat.
