If you are looking to send any files or data, whether it is through email, an instant message or a file, then your next step is to get an application to do this for you. One of the biggest mistakes people make when downloading applications to their computers is that they use the free version and then find out after using it for a while that there is a large file or database left on the computer that they cannot delete. This is because once they have been installed on the computer they are a part of the system and they cannot be deleted unless you manually edit the "main" database that is stored on your hard drive.
Another big mistake many people make when downloading software to their computers is that they don't back up their work before installing it. If you think about it, you need a backup program in order to make sure that your data is safe. This means that if you lose your files during the installation process, then you have a way to restore them without losing any important information. With all of the great programs out there, however, it can be difficult to know which one is the best.
If you are looking for something for your phone or tablet, you will want to choose one that is free and has a good reputation. If you have a high end device such as a Blackberry or Android, then you are going to want to pay a little more. You also have the option of buying software that will work with other devices, but these usually aren't free. This is why you should do your research first to find out what software you are interested in.
