Effect on NTFS File and Folder Permissions When Files and Folders Are Copied and Moved in Windows 10

Supporting NTFS Permissions

When you assign or modify NTFS permissions to files and folders, problems might arise. When you copy or move files and folders, the permissions you set on the files or folders might change. Specific rules control how and when permissions change. Understanding these rules helps you solve permissions problems. Troubleshooting these problems is important to keep resources available for the appropriate users and protected from unauthorized users.

Effect on NTFS File and Folder Permissions When Files and Folders Are Copied

When you copy files or folders from one folder to another or from one volume to another, permissions change

When you copy a file within a single NTFS volume or between NTFS volumes, note the following:

• Windows10 treats it as a new file. As a new file, 1t takes on the per. missions of the destination folder.

• You must have Write permission for the destination folder to copy files and fold. ers.

• You become the creator and owner.

When you copy files or folders to FAT volumes. the folders and files lose their NTFS permissions because FAT volumes do not support NTFS permissions.

Effect on NTFS File and Folder Permissions When Files and Folders Are Moved

When you move a file or folder, permissions might or might not change, depending on where you move the file or folder.

when you move a file or folder within a single.NTFS volume, note the following things

• The file or folder retains the original permissions.

• You must have the Write permission for the destination folder to move flies and folders into it.

• You must have the Modify permission for the source file or folder. The Modify permission is required to move a file or folder because Windows deletes the file or folder from the source folder after it is copied to the destination folder.

• You become the creator and owner.

Facts to Know About Moving Between NTFS Volumes 

when you move a file or folder between NTFS volumes. note the following:

• The file or folder inherits the permissions of the destination folder.

• You must have the Write permission for the destination folder to move files and folders into it.

• You must have the Modify permission for the source file or folder. The Modify permission is required to move a file or folder because Windows deletes the file or folder from the source folder after it is copied to the destination folder.

• You become the creator and owner.

When you move files or folders to FAT volumes. the folders and mes lose their NTFS permissions because FAT volumes do not support NTFS permissions.

p When you move files or folders within an NTFS volume, permissions that have been directly assigned to the file or folder carry over to the new location. In all other cases of moving and copying. existing permissions are lost. and the object will inherit permissions from the new parent. When moving to a FAT volume. permissions are lost entirely.

How to Troubleshoot Common Permissions Problems

some common permissions problems that you might encounter with  solutions that you can use to try to resolve these problems.
A user cannot gain access to a file or folder. If the file or folder was copied or moved to another NTFS volume, the permissions might have changed. Check the permissions that are assigned to the user account and to groups to which the user belongs. The user might not have permission, or might be denied access either individually or as a member of a group.

You add a user account to a group to give that user access to a file or folder, but the user still cannot gain access.For access permissions to be updated to include the new group to which you have added the user account, the user must either log off and then log on again, or close all network connections to the computer on which the file or folder resides, and then make new connections.

A user with Full Control permission to a folder deletes a file in the folder, although that user does not have permission to delete the file itself. You want to stop the user from being able to delete more files.
You have to clear the special access permission, the Delete Subfolders And Files check box, for that folder to prevent users with Full Control of the folder from being able to delete files in it.
