Often times, when we are working on files on school computers, we might email the document to ourselves if we don't have a flash drive or if we find that method more convenient. However, when we download the file from our email accounts to edit them on school computers, we would click on "Open" in IE or "Open With" in Firefox.
     Afterwards, when we try to save the file, there is no "Save" dialog box. Then, when we try to open the file again, there is no way to find where the file is saved. The reason being, when you click on "Open," your file is saved to a temporary folder which is located in your AppData folder  in your user profile. However, most of us don't know or don't have the time to go on a scavenger hunt for a paper that is due next period.
     The solution to this is to click on "Save" in IE (Internet Explorer), or "Save File" in Firefox. Save the file to the desktop (My Documents, or any other type of file that you can easily locate), then open the file and edit it from there. That way, the file is not saved in a temp folder that is cleared after you log off, but in a persistent folder that you can actually locate. Be sure to save your document often, because there are still times that you can loose a file because of a BSOD (Blue Screen of Death).
