Hi Rahendra,
I understand that, you want to remove read-only attributes for a folder that is custom created.
Refer these steps and check if it helps.
To view or to remove the Read-only or the System attributes of folders
Warning: If you remove the Read-only or System attribute from a folder, it may appear as a ordinary folder and some customizations may be lost. For example, Windows customizes the Fonts folder and provides a special folder view
that permits you to hide variations, such as bold and italic. It also permits you to change the folder's view settings in ways that are specific to fonts. If you remove the Read-only and System attributes of the Fonts folder, these customized view settings
are not available. For folders that you have customized by using the Customize tab of the folder's
Properties dialog box, the folder icon and other customizations may be lost when you remove the Read-only attribute.
If a program cannot save files to a folder with the Read-only attribute, such as My Documents, change the Read-only attribute to System by using the Attrib command at a command prompt.
a. Type “cmd” on the Start screen.
b. Right-click on it and select “Run as administrator”.
c. Type the following command and press Enter:
To remove the Read-only attribute and to set the System attribute, use the following command:
attrib -r +s drive:<path><foldername>
For example, to remove the Read-only attribute and to set the System attribute for the C:\Test folder, use the following command:
attrib -r +s c:\test
Be aware that some programs may not operate correctly with folders for which the System attribute and the Read-only attribute are set. Therefore, use the following command to remove these attributes:
attrib -r -s c:\test
