The EFS:COPYRAW option allows you to copy files from a Windows file system with exact preservation of its data and settings. This can be helpful when deploying applications that require specific files, such as an image file or an application configuration file.
In this guide, you will learn what the EFS:COPYRAW option does and how to use it.
What is the EFS:COPYRAW Option?
The EFS:COPYRAW option is used to copy files from a Windows file system with exact preservation of their data and settings. This means that when the file is copied, it is duplicated exactly as it exists on the file system, including attributes and permissions.
This can be helpful when deploying applications that require specific files, as it ensures that the files are exact copies of the originals.
How to use the EFS:COPYRAW option
Using the EFS:COPYRAW option is fairly straightforward.
First, you need to open an elevated command prompt. This can be done by typing "cmd" into the Start Menu, and then right-clicking on the resulting command prompt icon and selecting "Run as administrator".
Once you have opened the command prompt, you can use the following syntax to copy a file:
copy source_file_name destination_file_name /T /E /C /K /EFS:COPYRAW
In this example, /T tells Windows to preserve the original timestamps of the source file, /E tells it to preserve the original owner and group information of the source file, /C tells it to continue copying even if there are errors, /K tells it to preserve the original attributes of the source file, and /EFS:COPYRAW tells it to preserve the original data and settings of the source file.
