Is there a way to determine the free space on a drive by using a text file ?

I have a path to a folder which is stored in a text file: D:\Projects\Videos\current\ I want the program to take the drive letter from the text file and then show the space on the console. Currently my code is as follows which only shows the free space on my root drive C.
static void Main(string[] args)
{
var list = new List<string>();
var DrivepathTxtFile = new FileStream("LocatedPath.txt", FileMode.Open, FileAccess.Read);


StreamReader reader = new StreamReader(DrivepathTxtFile);

string DrivePath;
while ((DrivePath = reader.ReadLine()) != null)
{
list.Add(DrivePath);
}

DriveInfo[] Drives = DriveInfo.GetDrives();

foreach (DriveInfo d in Drives)
{
Console.WriteLine(d.TotalFreeSpace);
Console.ReadLine();
}
static void Main(string[] args)
{
var list = new List<string>();
var DrivepathTxtFile = new FileStream("LocatedPath.txt", FileMode.Open, FileAccess.Read);


StreamReader reader = new StreamReader(DrivepathTxtFile);

string DrivePath;
while ((DrivePath = reader.ReadLine()) != null)
{
list.Add(DrivePath);
}

DriveInfo[] Drives = DriveInfo.GetDrives();

foreach (DriveInfo d in Drives)
{
Console.WriteLine(d.TotalFreeSpace);
Console.ReadLine();
}
I copied the code straight from the MS page and this obviously does not work as the code is picking my C Drive's space.

Path.GetPathRoot() compare that to the Name property of the drive info

yes. I am having issue there too. ok a bit confused. I added the pathRoot to see the DrivePath string. I do not understand the comparing with the Name property part tho. string pathRoot; pathRoot = Path.GetPathRoot(DrivePath);

Does it specifically have to be done via a text file and a certain drive? Any reason you aren’t just getting the capacity of all available drives?

Yes I want it to be done specifically by text files.

I was trying to figure out how exactly this worked. I still consider myself new to C# 😅
