When I use the subject object to get a list of files, it is capturing a temp file in the folder. How do I stop this? When the process runs, I'm getting the error "Excel cannot open the file '~$2018-04 44310000.xlsx' because the file format or file extension is not valid". I am running the process for May, so it is opening April, updating, and saving as new month. Many steps later (plenty of time for temp of 04 to go away), the file list is being retrieved with the utility. When I do it manually, the temp file disappears immediately after the "save as" new month file.
