Windows 10: How do I change file type ?

I had to install a newer version of a program. Now when I open a folder, all the files still have the old image and it shows the file type as the old version, so when I try to open a particular file, it tries to open in the old version. How can I change the files to the new version ?

How to change default app for file type

'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.

And, once enabled, is available in Settings > Apps > Default apps.

 

How to change default app for file type

@Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.

Change Save As File type

Hi Patrick,

Thank you for writing to Microsoft Community Forums.

1. What type of files are you trying to save?
   
2. What type of File formats are you referring to?
   
3. Are you facing this concern with all Websites?
   

However, Try the below suggestions to change the default programs & File associations in Windows 10.

Method 1. Choose a Default Program for specific file types (extensions).

1. Right click on the Start menu and then choose
Control Panel. Set the View by to Small icons and then choose
Default Programs.

2. At Default programs options, choose
set your default programs.

3. At the left pane select the application that you want and then click:

a. Set this program as default to make the selected application as the default application to open all files types that it can handle, or

b. Choose defaults for this program to choose which specific file types the selected application can open by default.

b1. If you select the Choose defaults for this program option, then a new window will open that lists all the extensions (types of files) that the selected program can handle (open). Look at the list
of extensions and select any other extensions (files types) you want to be opened by the selected program. After making your changes, click
Save.

Method 2. Associate a specific file type (extension) to open with a default program.

The second method is to choose a default program by extension.

1. Go to Control Panel >
Default programs and select Associate a file type or protocol with a program.

2. From the list of file extensions, select the extension that you want to change the default program to open with and then click
Change program.

3. Finally select from the suggested programs or select
More apps to find another program on your computer, to open files with the selected file extension.

Hope it helps,
