"Can't copy file: Access Denied!"
"I like taking photos using digital cameras. Yesterday, I planned to transfer all my pictures to my computer via a USB device. But when I selected all of them and attempted to pasted them in USB drive, I got an error message: Error Copying File or Folder. Access is denied. That confused me a lot since it is the first time for me to meet such issue. Is that the USB flash drive dead? Any one has any idea as to what I should do here? I am running Windows 10 64 bit."
Why does the error appear?
Before dealing with "Error Copying File or Folder. Access is denied" error, we can check out the following factors that help explain why this error happens.
•The hard disk is set into read only mode by mistake or corrupted file system. When the hard drive is write-protected, you cannot make any operation on the disk.
•The target disk is corrupted. If the target disk or partition is corrupted or damaged due to bad sectors or disk errors, it won't be able to read or write data anymore. Then the "Access is denied" error message might appear.
•The file or folder ownership has changed. In some cases, if you lose the ownership of certain files or folders, you cannot move, copy, delete, edit or save data.
•You don't have the appropriate permissions. Permissions are a series of rules that determine if you can access the files and folders. If you don't have one, you cannot change your data as you want.
•The files are encrypted. As for files that are encrypted by users for the sake of protecting data, you are not allowed to copy or move them to another location.
