Tell the Association of a file with a program

When Windows encounters a file with the extension can't identify, he asks what to do, usually suggesting a check of the Web or proposing to use a program already installed.  Generally, I take the notebook initially to see if the file gives a clue as to what it is.  There is a box already checked, asking if you want to use Notepad to open this type of file all the time.  I always turn off this box, but I forgot to do it earlier today.

The notebook was the wrong program to try to open this file extension, but now he is engaged and shows all files with this extension as .txt files.  I can bring to the top of the screen to select another program to associate with this extension, but no programs on my computer are applicable in this case.  Is it possible to go back and mark this extension simply as 'unknown', which is what it was in the first place?  Is not part of the options, but should certainly be.  Another good thing would be to disable permanently this box for always use Notepad or other open file.

Hey, guys.

I found a solution, and it's a very easy.

The first thing I did was a system restore, back to a week ago.  That did not help.  Although the restoration was successful, the. Extension TOL has not yet shown on a folder that contained this file type.

I went on the Web and looked for «Windows does not have the extensions of files...» "or a similar term.  The first who came (from 2005) simply told, go to: Display/Control Panel/folder Options and uncheck the box: "Hide extensions of known file types".  Voila, the. TOL and same. TXT file extensions appear again very well.  So even if Windows says that the. Extension TOL as an "unknown" file type, deeper inside of her to think that he knows what it is.

This does not explain why the. TOL disappeared and did not go back, but the functionality you need is back and I trust what I see on my screen is probably what will be visible on the screen of the recipient file.

Thanks again to you two; If you think of anything else, let me know.

  • I want to make an empty file with no program that is associated with it.

    I want to make an empty file with no program associated to it, but when I try to create the shortcut displays an icon. How can I create a file with no icon on it.

    You can simply rename the file without an extension, or you can create files at the command prompt using one of the following methods:

    Use the con command copy and then issue a command CTRL + Z to exit the console example:

    stupid copy file name
    CTRL + Z

    Use the Fsutil command:

    fsutil file createnew

    example:

    fsutil file createnew myfile 0

    How to change the extensions on several files with Windows 7?

    You hear no doubt, is that your movie software will only recognize certain types of image file formats.  If this is the case, you will need to reformat format files to any format PNG is recognizable by the software.

    Rather than we guess, please identify your «film» software

    Download and install IrfanView, which is a free utility for images.  http://www.IrfanView.com/

    IrfanView has the ability to read a great many formats of image files.  It can also convert image files formats.  And even better - for you - it can do all these things on a batch of files.

    As test, after I installed IrfanView, open one of your PNG files.  Now click on file > save as, and select the 'Save as Type' to be little matter the file type of your movie software will accept.  Save the file.  Make sure your movie software can accept the new file.

    Once you are convinced that you can modify files that you have in a format that you can use, use IrfanView

    File > Batch Conversion/Rename command.  If necessary, see IrfanView help on this topic.

  • How to save the string in a file with some special characters

    Hello

    I m using MD5 - llb to create a password.

    So, I want to save this MD5-string to a file and read it later abd compared again.

    Works perfectly with a proplem:

    Some Word create a '\r' in the string of MD5 and when I save this string in a file and read it at the time its read as a '\n' for the comparison does not work.

    My question is: How can I record a string exactly as if it were somewhere and read back (also the invisible characters)

    For example, the word: heinz

    is in MD5: \r\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95 (string as display codes indicator)

    When I save the string in a file, then I rerad back: \n\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95

    I used the "write text file" and "read text file".

    What should I use to record and play back the same thing?

  • How to remove the comments of several files with the Action Wizard, without losing the OCR?

    Hey everybody,

    With the help of Acrobat DC Pro.

    I used Action Wizard previously to remove comments (or more specifically, highlight) documents.  I created a custom command using 'Delete hidden information' and not selected everything but 'delete comments '. However, my files keep losing OCR, I did after I do this.

    I also tried to use the 'Sanitize' tool to delete comments, and it's the same thing.

    Is it possible to automate this process in a way that maintains the OCR?

    Thank you!

  • Create a script to list all the .bat and .cmd files with the dir command &

    Hello

    Im trying to create a script that will list all the .bat and .cmd files in a specific folder and add the data to a new file (file.txt) - example below:

    dir c:\>desktop\file.txt/OD
    dir d:\>>desktop\file.txt
    dir f:\jobs\*.bat>>desktop\file.txt/OD

    IM able to search the F drive and the list of all the .bat files using a generic parameter, but ideally id like to search for .bat and .cmd files, but whenever I have it try does not work. Any ideas?

    I tried the following:

    dir c:\>desktop\file.txt/OD
    dir d:\>>desktop\file.txt
    dir f:\jobs\*.bat,*.cmd>>desktop\file.txt/OD

    Any help is appreciated, the reason for which I need to check all the .bat and .cmd files is to ensure that the scripts on a cluster are all data, so need them all listed in a doc if possible

  • Update the system: remove left files in C:\Program Update\session\ of Lenovo?

    Downloaded updates are deposited under C:\Program Update\session\ of Lenovo.

    Can delete these files after you install the updates?

    Yes, you can delete the contents of the folder after the installation of the drivers/software. The next time that you run the system update, you will probably see that the folders and multiple files (such as XML files) under the 'session' folder will be recreated/downloaded again, but these files will not take a lot of space. You can also move the contents of the record session on a USB drive or elsewhere. That way if you need to reinstall your operating system at some point, you can install the update system and copy the content under the folder of the session again. Then, you don't have to download all the stuff once more, as Lenovo download is extremely slow.

    I don't know if it is possible to save the folder of session elsewhere and not in the system update folder. Maybe it's possible to change some registry keys or configuration files. It was never a problem for me if you ever tried to change this path. For backup using a backup program that allows to create incremental backups, then the files that is not changed will be saved only during the creation of the full backup. When the full backup is created incremental running not backup those files again unless they are changed.

  • CC of the organization saves all files with the icon to the?

    Hi, since a few weeks, I have the following problem: when I save a project in the Organization of the CP, the file still gets .prproj extension but with the icon of the hearing (AU), not creating icon (Pr). problem is that when I fix this kind of files to an email (or send it via us transfer), the other can not open it. It ' has a new number, before it was working OK. anyone understand what is happening? Thank you.

    the icon showing the Audition even if it's a .prproj file may be a separate issue from the other person is not able to open it.  both computers use the same premiere pro version? If it is a simple installation you can try export xml as a work-around.

    If you are on windows, and there is a problem with the file types associations, then right-click on the file and choose 'Open with'. then tell him to always use first pro for .prproj

    If you do not see open with, try now shift while clicking on the file.  This will only change the icons and behavior by double clicking on a file to open it on your computer. He can't fix anything for the other person to open your file.
