Still didnt get any answer:How can I open files that have a QF extension (.QF)? The file is a book's test bank

What is a qf extension?  You need the program that created this file to be able to read it.  You could open with notebook and see if you could discern the cryptic content of this file.  It's a non-standard file so you need the non-standard program that created it.  Good luck.

Try downloading the file to your computer. Then go to my computer find the file and open it up. It should work.

That means that the file you tried to open cannot be opened in that program.\n\nSo either you need to:\n1. Update your program\n2. Get the appropriate codec (like DivX or Xvid)\n3. Download a new program that can open up the file type.

That file extension requires a program called After Shot.  However, it should open under and Corel product since Corel bought JASC softeare back in 2004.  Try opening it under Paint Shop Pro, if you have that program.  Also, open up windows explorer and make sure the file does not say 0kb.  If it does, its a bad file and contains no data.  Also, see the link below, it will help you fix this error.

Re-Download it as the correct file type?\nTry changing the files properties with regard to what it opens with?\n\nThats all I can come up with! =(

Not sure what you are asking. The .exe extension just indicates that the file is an executable utility or program. What are you trying to convert?

you probably don't have the correct program to view the file. Check the Microsoft website to see what you need to open it.

If you do not have MS Office, MS Word, or any other software that uses the '.doc' format, you will not be able to view files of that format.  Most likely, this format will not be available in the drop-down box mentioned above, either.\nAlternatively, you should still be able to save the files as a valid .doc file by typing quotations around the full file name in the 'file name' section of the Save screen.\n\nFor example, if you have a document titled 'example' and you want it saved as a .doc file, but have no other option of saving it as such...in the 'file name' box simply type the following:\n"example.doc"\nwith the quotation marks.\n\nIn order to view the file, however, you will have to have the necessary software installed on your system.  The extension has to be assigned to a valid program such as MS Word or WordPad I believe views .doc files, as well - though some of the advanced formatting available in MSWord will be lost when viewed with WordPad.\n\n***RESPONSE TO ADDITIONAL DETAILS***\nDid you try putting the quotation marks around the file name...such as\n"example.doc"\n\nWhen you add the quotations, it will save the file in the format specified regardless of what is in the "save as" box.\n\nAlso, open any folder (such as 'My Documents', for example) and go to Tools - Folder Options.  Click the 'File Types' tab and scroll down the list of file types until you find 'DOC'.  If you find it, down near the bottom where it says 'Opens with...' click 'Change' and browse for the program you prefer.\n\nIf you can't find it, click 'New', and in the top box, type\nDOC\nthen click 'Okay'.  Find DOC in the list, then follow the instructions above to select the appropriate program for it.

Your file extensions are messed up.\nI'm not a mac user, but that is what i guess is the problem.\nMost of your downloads are associating themselves with the text application, so they open up in that application.\n\nLook in the apple support knowledge base on how to change extensions on mac. \n\nhopethat helps.

Rename the file extension from .bak to .dwg\nNothing to it!
