Could not copy "obj\Debug\etc" to "obj\Debug\etc". Exceeded retry count of 10. Failed.

 1. Stop the Running Application

• Make sure your app (yourapp(ur application name)) is not running.
• Open Task Manager (Ctrl+Shift+Esc) → go to Details tab.
• Find yourapp(ur application name)) → End Task.
• Rebuild your project.

2. Clean and Rebuild

• In Visual Studio:
  • Go to Build → Clean Solution
  • Then Build → Rebuild Solution
• This clears the obj and bin folders and rebuilds everything fresh.

3. Check for Debugger/Antivirus Locks

Sometimes, even if the EXE isn’t running:

• Antivirus software may be scanning or locking the file — temporarily disable real-time protection or add your project folder to exceptions.

• Visual Studio Debugger might not have released the file — close the solution and reopen it.

4. Manually Delete Locked Files

If the above doesn’t work:

1. Close Visual Studio.
2. Open File Explorer → navigate to your project folder.
3. Delete the folders:

   bin\Debug
   obj\Debug
   

4. Reopen Visual Studio → Rebuild.

If Windows says “file is in use,” use a tool like Process Explorer:

• Download from Microsoft Sysinternals.

• Search for (yourapp(ur application name)) → right-click → Kill Process.

5. Disable Parallel Builds (Optional)

If your solution has multiple projects:

• Go to Tools → Options → Projects and Solutions → Build and Run
• Set “maximum number of parallel project builds” = 1

This avoids concurrent file access issues.

6. Check Post-Build Events

If you have a post-build script that copies or runs the EXE, ensure it’s not launching the app before the next build.

How to download (clone) a Git repository into a specific folder ?

If you want to download (clone) a Git repository into a specific folder, you can do it very easily using the git clone command with a folder path at the end. 

Option 1 – Clone directly into a specific folder Command format: git clone 

Example: git clone https://github.com/username/Notes.git D:\Projects\NotesApp 

This will: Download the Git repository into the folder D:\Projects\NotesApp If the folder doesn’t exist, Git will create it automatically. 

Option 2 – Clone in current folder with custom name. If you’re in a directory (e.g. D:\Projects) and you want to clone the repo into a subfolder with a custom name, do this: 

cd D:\Projects (Enter)

git clone https://github.com/username/Notes.git 

MyNotes It will create a folder called MyNotes inside D:\Projects and put the repo code there.
