The issue with the files containing the "+" character in their file name not being downloaded when downloading a SharePoint document folder is a known issue with SharePoint. This is because the "+" character is a reserved character in URLs and needs to be encoded before being used in a URL.

One workaround for this issue is to rename the files to remove the "+" character before downloading the folder. You can do this by navigating to the document library in SharePoint, selecting the file(s) with the "+" character in their name, clicking on "..." and selecting "Rename". You can then remove the "+" character and save the changes.

Alternatively, you can try using a third-party tool to download the files from the SharePoint document library. These tools may handle special characters in file names differently and could be able to download the files successfully.

Thanks so much for the information, ShijurajJayaraj!
I have searched Microsoft document and nowhere mentioned that the "+" character is a restricted or reserved character.
As the file with "+" in the name is one of the files in the programming installation, rename the file will cause the installation fail. I will look for some 3rd party tools for download files from SharePoint.
Again, much appreciate.
