Problem deleting OneDrive folder due to multiple checked out files

you need to login to the sharepoint document library and then 

If you check out a file and don’t make changes to it, or you make changes that you don’t want to keep, you can simply discard the checkout, rather than saving the file. If your organization tracks versions, a new version is created each time you check a file back into the library. By discarding the checkout, you can avoid making new versions when you haven’t made any changes to the file.

1. Go to the library where your file is saved. (If you’re looking at a view of the library on another page, you may have to click the title of the library first. For example, you may have to click Documents first to go to the Documents library.)
2. Select the file, or files, that you want to discard changes for, click Files and then click Discard Checkout.
3. Click OK to finish discarding the checkout. The green arrow disappears from the file icon when the file is checked back in.

Thanks for getting ba to me! I should have been more clear in the question. I am trying to delete the entire folder, but I can't due to a very large number of checked out files. I am looking for a way to discard checkout on all these file, so I can delete the entire folder. Doing that one file at a time would be extremely time consuming. Is there a way to do that using a powershell script, or some other way that would allow me to discard all open files in that folder, so I can delete it?
