.NET desktop app not able to delete files on Windows 10.

[testwinten]

I have a simple app that tries to delete file located at c drive on Windows 10.
But Win10 does not allow to delete file through c# .net code using File.Delete() . Throws error "access is denied".
File creation is allowed but deletion gives exception.
Can anyone help with this?

Thanks in advance.

Hi testwinten,

it sounds like a permissions issue, right click the file/folder you are trying to delete > Properties > Security and check what the settings are for your user instance!. You may have to edit the settings to suit yourself?:

I hope it helps.

The file as all the permissions as mentioned by you.

Still not able to delete it.
Sharing the code for your reference.

public MainWindow()


{

InitializeComponent();

string path = "C:\\Temp\\Test.txt";

try


{

// Delete the file if it exists.


if (File.Exists(path))


{

File.SetAttributes(path, FileAttributes.Normal);

File.Delete(path);

}

}

catch (Exception ex)


{

Console.WriteLine(ex.ToString());

}

}

Error I get is:
Access to the path 'C:\Temp\Test.txt' is denied.

Try this. Here are two "fixes"
run both in a Command prompt (Admin)
They will add a context to the right click of the folder. Use the take owner context
first and see if it helps.

Use 'EMCO MoveOnBoot' its on this site: https://emcosoftware.com/move-on-boot always works for me, hope this helps, cheers.

I would like to programmatically delete file. This tool is deleting the file but I want it to do it in my .NET application.

Can you manually access the folder where the files are in the MS.Net folder on C: drive?.

Yes. I can access it manually.

 

[testwinten]

One update:
When I try to use "SetAccessControl" method and assign fill access control to file, I get this exception "Attempted to perform an unauthorized operation."

 

[Wolfie]

And have you tried deleting the files from there? (The MS.net folder):

What user account type are you using?, MS or local, guest or admin, what version of W10 do you have?.

 

[testwinten]

I tried deleting text document from there. But getting same error "Access to the path 'C:\Windows\Microsoft.NET\assembly\test.txt' is denied."

Windows 10 version: WINDOWS 10 Enterprise

User account type: local(having local admin rights)

Are the file attributes "Read only" ?:

You might need to take out that tick so to speak.

Attributes are not marked has "Read only". It has all the permissions

 

[Wolfie]

It suggests using "Safe Mode" here:

I don't have anything else myself sorry.
