HTTP Error 404 - File or directory not found. When downloading a file.

We have customized the physical location as well as file download behavior by using the sample code files 'CustomFileSystemProvider.cs' and 'FileSystemHandler.ashx'. The implementation works fine on developer machine, but getting 404 error on production server.

Hello Suresh,

Most probably the experienced error is due to permission limitations. You can find detailed information on how to test for such in the following FileExplorer's help article: Troubleshooting

I hope this helps.
