My computer will not open haverstraw.1260861867, image-4.1261143638, hopper-railroad-10bis.1260860380, or 902561.kmz. Please help me.
When it comes to opening mysterious files the information you need to have is the extension. In order to open a file, you need to know either the program that created it, or a program that can open it. The file extension tells you the program that created the file - most of the time - or at least narrows down your options. File extensions can also hint at related or compatible programs that might be able to open the file, even if they didn't create it.
In this case, the only extension that we have to work with is the KMZ. The others may have the same extension and you just left it off. Otherwise, once we are finished with KMZ you can write again with your other file mysteries.
For KMZ, the associated program is Google Earth. There is a Filetonic file extension database that is devoted to helping you find the programs that created unknown files. You can find the database by clicking the link above. KMZ files are compressed sets of one or more files that can be viewed in Google Earth.
Since image files are usually very large, they are also usually compressed, and the same is true of the KMZ type. KMZ files are compressed using a ZIP compression and so can be unzipped with any generic zip utilities. Before you can open the file, you might need to rename it from a KMZ to a ZIP file for compatibility. To rename a file, simply click the text box that contains the name and manually change the extension, then press Enter. Once you have unzipped it, you should change the format back to KMZ if you plan to use the file again.
Common zip tools include WinZip, 7Zip, the Windows XP Compressed Folders Tool for Windows of Stuffit. You may already have a zip utility on your computer. A quick search in your Start directory should let you know. If not, you can google the program that you choose and install a download - they are usually free. I hope this solves your problem. Good luck!
