Awesome Hidden Windows FeatureAnd by awesome, I mean totally _not_ awesome. A co-worker just called me over to his desk to check out some odd behavior. He had just extracted a zip file that contained a "Complete Web Site."
When you right click on a page and choose "Save As," you have the choice of saving the HTML only or the Complete Web Site, which will include all images, CSS, etc. A friend saved a page with the "Complete" option, zipped it, and sent it to my co-worker. He unzipped it to find two items: index.html and index_files (a directory). That's normal, we've seen that before. Since my co-worker only needed the HTML, he decided to cut and paste the HTML file to another directory, but when he did the folder automagically followed.
That's right, the folder was moved without any user interaction. We thought that Windows may have somehow linked the folder to the HTML file since it was saved using the "Complete" method. To test this theory, he deleted index.html and guess what happened. That's right, the index_files folder was automagically deleted. What an awesome feature. So if you've named any of your folders the same as an HTML file with "_files" on the end, you may lose your files.
Thank you Microsoft for screwing up basic file and folder management. The entire world appreciates it!
