Windows 10: How can i change the extensions of a file?

Hey!

I was wondering if we could change the extensions of a file If it's possible. Does anybody knows how to that?

:)

 

File extension *.docx

Hi Randy,

To change the file extension when saving a document in Word 2013, you may follow the steps below:

• Click on File; then, select Options from the list.
• In the Word Options window, choose Save.
• Under Save files in this format, select *.doc from the list.
• Hit OK button to confirm and save the changes.

If ever your Word 2013 application is not recognizing the changes you have made, you may restart the application; however, if the issue still persists, we suggest that you repair it. To do this, see this
link.

We would appreciate it if you could get back to us and provide us your feedback.

 

Remove (not change) file extension association

I mistakenly associated a file extension with .pdf. I've found many instructions on how to change (swap) the file associate from one extension to the other, but how do you remove the association completely and return it to "Choose a default" ??

This user was very helpful (How to UNSET/REMOVE a default app for file type).

I took the suggested steps above and it removed the association but didn't return it to "Choose a default" ... this has caused a thumbnail app to work for every file EXCEPT the ones i mistakenly associated, then did the work around on. This is affecting
productivity as I'm working with over 1,000 files (and growing). Since 145 people said they had the same question, please Microsoft, can you answer or solve this problem? Please help. Thanks.

 

Can a file extension(.flv) be added to Default Program Associations.

Hi Fred,



Thank you for posting your query on Microsoft Community.



I understand that you are facing issues associating a particular file extension with a program on Windows 10. I apologize for the inconvenience caused to you.

To assist you better, please provide the information:

When you say that "Default Program Associations", are you referring to the list of default applications in default programs settings?



I want you to be informed that all the file extensions is listed in the default program settings which is displayed under
Associate a file type or protocol with a program.



In default program list, all the programs or application will be listed. Then we can select each program as default program for opening a particular file.

I suggest you to refer to the below steps to make default program for a particular file extension.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Default Programs and click on Choose Default for this Programs.

4. Select .flv file from the list.

Also you can try other steps to associate the a particular extenstion with the program.

and search for .flv extension from the list.
