I have a folder shared and I copied it to another computer just fine, but two individual files say I don't have permission to copy them. And the filename is in green in Windows explorer on both the copy-from (W7) and copy-to (Vista) PC. I never saw this before, what does it mean and how do I fix it? These two files are nothing special.
Files shown in Green are encrypted.
Files shown in Blue are compressed.
Both of these actions are fairly low level file system / Windows actions that effect how the file is stored, but not it's structure or content (like compressing in to a zip file would, for example).
The two are mutually exclusive - NTFS cannot compress and encrypt a file at the same time.
Files encrypted in this was can only be decrypted by the user account that performed the original encryption.
