I am using windows os as my device.
I want to copy all files and folders from my internal hard drive to external one using Total commander program.
The reason of using Total commander is copy long file names that windows os can not handle it.
During copy files and folders with total commander there is an option to "Copy NTFS permissions" too.
What is this check box?
Is it necessary for my External hard drive?
Should i check it or not?

This option is for when copying from NTFS to NTFS.

With the option ticked, the file permissions on the source file are copied as-is. This may cause a problem if the target folder has different permissions, for example a different owner, which may prevent this owner from using the files. It is less important if you are the owner of both source and target.

With the option unticked, the copied file will inherit the permissions of the folder to which it is copied, meaning that it will have no permissions of its own that are different than that of the target folder.

Addition by @Tonny:

To add: With the checkbox OFF it has the same behaviour that Microsoft's own File Explorer has. With the checkbox ON you may need admin-rights to apply the permissions on the target files and the copying (when doing a large amounts of files) is a bit slower. For most people keeping this OFF is the best option. The ON setting is mostly of interest if you need to re-create a source folder-tree on a target disk exactly, including original permissions. Most users will never have a need for that.

    @SilverLight To copy files to a transfer-disk (or USB stick) to be used on different computers this REALLY should be OFF.

  • @Tonny Really appreciate for help and comment. Can total commander copy all files and folders in the right way? I do n't want to lose anything in the future. Apr 10, 2022 at 15:44
