Delete files in subfolder using batch script

I have to delete files from a sub folder with a same name. My file path is like as follows.

d:\test\test1\archive\*.txt
d:\test\try\archive\*.txt
d:\test\model\archive\*.txt

I tried deleting using del command in batch script. But there are more than 100 folders with in the folder "test". So it is very difficult to use del for each and every path.

Except for the parent folder name of "archive" folder, everything remains the same for all the paths. So I guess there might be some easy way to delete the files using batch script.

Can anyone guide me whether there is any easy way to delete the files using batch script? Or i have to repeat del for all 100 folders?
