SharePoint Allowing File Upload with Invalid Filename Starting with '$'

[aishwaryapise]

Dear Microsoft Team,

I am encountering an issue with SharePoint that contradicts the official documentation. According to the SharePoint documentation, filenames starting with the character $ are not allowed when uploading files. However, in our SharePoint environment, I have been able to upload files with names beginning with $ without any error or restriction.

The file names can't start with "~" (tilde) and "$" in sequence. "~$" is a prefix for lock files that office documents create when you edit a file. https://superuser.com/questions/405257/what-type-of-file-is-file
