Answer 1

I just need to get the name of the file.
Use Path.GetFileName() to get the name of the file , and use Path.Combine() to combine the the save path you want with the file name , try the code like below
var filesPath = Directory.GetCurrentDirectory() + "/files";
if (!System.IO.Directory.Exists(filesPath))
{
Directory.CreateDirectory(filesPath);
}
foreach (var item in files)
{
if (item.Length > 0)
{
var fileName = Path.GetFileName(item.FileName);
var filePath = Path.Combine(filesPath, fileName);
using (var stream = new FileStream(filesPath, FileMode.CreateNew))
{
await item.CopyToAsync(stream);
}
}
}

Seem like you want to get the file name base on your file path.
You can get it into way
using System.IO;
Path.GetFileName(filePath);
or extension method
public static string GetFilename(this IFormFile file)
{
return ContentDispositionHeaderValue.Parse(
file.ContentDisposition).FileName.ToString().Trim('"');
}
Please let me know if you need any help

I faced the same issue with different browsers. IE send FileName with full path and Chrome send only the file name. I used Path.GetFileName() to overcome issue.
Other fix is at your front end side. Refer this to solve from it front end side.
