I've seen people argue about this error in SharePoint and how annoying it is, but somehow people have found a solution, but annoyingly I have seen 0 answers to my error. You see, this error normally happens with folders and the folder having an empty file inside with 0 bytes, but even worse than that is my error, which gives me the error when I'm trying to delete A FILE.
Yeah, that's right, a file, an error that should be only for a folder, somehow appeared when trying to delete a file.
For this example, I tried to delete an Excel file inside Sharepoint Web, and the message popped up, for extra information I'm using an account with admin permissions, and even I can't delete it.
For some unknown reason right now I am not able to attach an image but I'll try to attach one when I figure out why I can't.
