What is a .WDSEML file?
A .WDSEML file is a special type of file that is used by Mozilla Thunderbird, which is a program you can download for free to manage your emails and read news. This file is important because it helps your computer search for specific things within your emails much faster when you use the search feature in Windows.
How do you get these .WDSEML files? Well, they are automatically created by Thunderbird if you tell the program you want to make your emails searchable by Windows. You can do this by going into the settings of Thunderbird. You click on "Tools," then "Options," choose the "Advanced" tab, click on "General," and finally, you'll see an option for "System Integration" where you can allow Windows to search your messages.
If you decide later that you don't want these files to be made anymore, you can just go back to the same place in the settings and uncheck the option.
Most of the time, you won't even see these .WDSEML files or need to open them yourself. They are used in the background by Thunderbird to help you find things in your emails when you search for them. If you delete one of these files, it doesn't mean your email is gone. It just means that it might be harder to find that email using the Windows search feature. And if you delete an email in Thunderbird, the .WDSEML file that was helping you search for that email doesn't automatically get deleted. You would have to delete it yourself if you want to get rid of it.
Remember, .WDSEML stands for "Windows Desktop Search Email," which pretty much explains what it does – it helps Windows search through your emails.
The main program you need to open or deal with these files is Mozilla Thunderbird. Since these files are not meant to be opened directly by users, Thunderbird handles everything related to them in the background.
