KB IssueCannot copy file cannot read from the source file or disk when you try to copy or move a folder.
Issue DetailsWhen trying to copy or move a folder to another location on your hard drive, you may encounter the following error.
Copy File Error
cannot copy file, cannot read from the source file or disk.
Or
Cannot create or replace (Folder Name): Access is denied.
Make sure that the disk is not full or write-protected
and that the file is not currently in use.
Recreate IssueWhen deleting a folder from the network, not all content may be deleted, as some files may still reside in the folder and are only readable by the computer and not accessible to the user.
Resolve IssueThese folders are hard to remove on your own; using the Del command from a DOS PROMPT will not remove the folder. However, there are ways to do it through a reboot and a DOS prompt; if done incorrectly, you could delete the wrong thing.
