What are data files? I looked in the dictionary but... My QUESTION relates to seeing them on my Samsung3s as well as on the DESKTOP. I'm trying to make file management easier and reduce the clutter when I open the 'files' folder. They appear to have no purpose as far as entertainment or links. They often have the same name almost as the music or video file I'm looking for so it's time wasting and problematic. Can I delete them on my phone or do I need to go through all the files and put them in a folder assuming that is possible? If they have no use other than system information why are they even visable? Data files are files you created. This includes word processing files, spreadsheet files, and files you've created with any SOFTWARE. So, you don't want to delete them, do you? Well, of course, you might want to delete files that you no longer want. But, be sure you no longer want them before you delete them.

Program files, on the other hand, are files the make the programs, i.e. software, on your computer work. Of course, you should not delete them. Doing so would break the program. If you want uninstall a program, do it through the TOOL found in Control Panel for your version of Windows.

Data files are, quite simply, files that contain data (which you may or may not have created yourself) and are readable by the user - as OPPOSED to system files which are of use only to the computer or installed programs.
