Auto open excel files in IE10? RRS feed

  • Question

  • Hello is there a way to always open excel files (xls, xlsx) in IE10? Also can you turn off file format and extension doesn't match in Office 2013? Sorry for the 2 part question. Trying to kill 2 birds with one stone.

  • Hi,

    We could follow these steps to open Microsoft Office Excel file with Internet Explorer 10:

    1. Rght click the Excel file;

    2. Point to "open with" and then  "choose default program...";

    3. Click "Internet Explorer";

    4. select the "Always use the selected program to open this kind of file" check box, and then click OK.

    In addition, we could unassociate file type and remove file extension associations as below:

    1.Open an elevated command prompt with admistrator privileges.
    2.Remove the file extension association from its assigned file type with the following command, follow by ENTER:
    assoc .ext=

    Replace .ext with the extension name that needs to be unassociated. For example, to disassociate WinRAR .rar extension, simply type assoc .rar =.

    Note that after disassociation of file extension from file type, the default program for the file type no longer been shown in the “Open With” list for the file extension.

    3.Then, clear and delete the default program used for the open command when launching files of this type by typing the following command, and press ENTER:
    ftype FileType=

    Replace FileType with the actual name for the file type associated to the file extension to be removed from the system. For example, for WinRAR, type ftype WinRAR=.

    Note that if you don’t know what’s the correct “FileType” to type, simply type assoc (associated file type will be shown after the extension) or ftype to get a listing of all file types defined in the system.

    After disassociation or unassociation of a file extension association, when user double clicks on the particular type of file, the dialog box will be prompted saying “This file does not have a program associated with it for performing this action. Create an association in Set Associations control panel.” and user is forced to click the only OK button. However, it’s possible to right click on the file, and choose Open With… option, then user can select a program from a list of install programs to open the file, and on the same time, set the correct and proper file association again.

    Best regards,
