  1. Invalid MS-DOS Function


    Hello,

    Could somebody please help, I have various files throughout my hard drive which error "Invalid MS-DOS Function" if I try and move or delete them however they "work" normally if I try and use them.

    I ran a check disk which returned no errors.

    I am feeling this may be a format job however I'd like to avoid that if possible ... any thoughts?

    :)

    You need to provide a clearer explanation of what you are trying to do that doesn't work.

    - What are you trying to delete and where from?

    - Are you using File Explorer to find the files you want to delete?

    - Do you get an error message when you attempt to delete a file? If so, what is it?

    Can you be more specific?

    What files (provide a few examples), where are they located?
    How are you trying to move or delete them? Is it via File Explorer?

  5. The files are located all over my hard drive and are of various types.
    The 4 files on my desktop i tried to delete by selecting and pressing delete.
    The 4 files in a program we write I could not rename or delete 4 of the multitude of files in the folder.

    I managed to fix all 8 files by re-installing the application (which has never had an issue on Windows 10) and then deleting it.
    I'm guessing there must be some corruption in the FAT

    Um Windows does not use FAT as the drive format, it uses NTFS. You should not be getting any type of MS-Dos error, because MS-Dos went bye-bye with XP.

  7. Sorry, I didn't mean FAT as in how the drive is formatted ... just the section of the hard drive which contains the directory/file structures.

    I know I should not be getting them, the problem is I am (well was) getting them and I need to find out why. Everything i found online kept talking about USB sticks on Windows 7 producing the same errors.

    Have you tried deleting it through command prompt? If it isn't working please post results of these 3 commands when entered in an elevated (run as administrator) cmd window (replacing "Path\Your File.zip" with the real path to the file).

    del "C:\Path\Your File.zip"
    dir /x /a "C:\Path\Your File.zip"
    attrib "C:\Path\Your File.zip"
     
  11. I am having the same problem. It's so frustrating! I cannot move, delete, rename. Always get this stupid Invalid MS DOS function.

  12. Not true. You can format and use drives formatted in Fat and Fat 32. Its the default file format for small USB thumb drives etc. DOS is gone though in your current Windows versions, its been replaced with command shell. The error messages are likely part of backward compatibility. That's my guess anyway.
