I have just updated to your latest version and can confirm that the file is now deleted from the import directory!
Thanks so much.
I can confirm at least the follow is true.
“I’ve tried to use a directory relocator plugin that will bring it to sermon-manager-import, but when it uploads, it won’t delete the original files.”
I am using the latest version of WordPress. I FTP the file to the import directory and click publish. The file is copied to the new location but isn’t deleted from the import directory.
