There is a command button on the toolbar of the Documents folder that says\n"Compatibility Files". Does anyone know what are they and why nothing is\nmentioned about them in the Vista documentation? (at least not when searching\non "Compatibilty Files").\n\nI ask because a program I was running created a folder and some files that I\nwasn't able to see in the Documents folder (or from a command prompt) until I\nclicked the Compatibilty Files button (by accident, really). The program was\na 32-bit Java program, and there were no compatibility issues I was aware of.\nMy file options were set to see hidden and system files, so I couldn't\nunderstand why the files weren't appearing. Clicking on this button showed\nthe folders and files the Java program created, and a few other files I was\nable to view before (however they showed different modification dates). I\nwasn't able to see most of the other files and folders in the directory in\nthis Compatibility Files "view," however. What happened?
