Delete a file which contains a particular piece of text in its name

[vivekkabra]

Hi!
I want to delete any file in the ‘Download’ folder which contains .temp in its name.
For example, if there is a file named Image1.temp in the ‘Download’ folder, then I want to delete that file. I took a glance at different blocks included in Taifun’s File extension but nothing struck my mind to solve this purpose.
How can I achieve this?
Please kindly help me.

Thanks!

Is “.temp” the extension of your files or is it included in the NAMES?

.temp is the extension of the file.
Thank you so much @HeyAveHey.
Seeing your blocks, I got an idea of how to do it and solved my purpose using this:

As in my case, only one file with the extension .temp can be there at a time, it’s certain that FileList will contain only one item, which will definitely be at index 1.

Thanks to @Taifun as well for this wonderful extension! (App Inventor Extensions: File | Pura Vida Apps)

Thanks again for helping.
Have a great time!
