EFS file copy

Hello,
when I copy encrypted file, I have thought that its encryption state is
not maintained, but this seems not to be true. When I copy encrypted file,
its encryption state is maintained both when using Drag'n'Drop, Copy/Paste
as well as with copy command.
Is it the right course of actions?

Ondra.
 
there are some differences between win2k and XP, but overall, the system
always tries to preserve the encryption state if possible and when it
cannot, it will warn the user.
 
And with other parameters (attributes) such a Hidden or Compressed?
And what is the difference on XP with the EFS files?

Ondra.

There are some differences in Explorer and also in the cmdline tools (xcopy
and copy). AFAIK, we don't have a matrix of these changes available
anywhere. For internal testing of EFS copy behavior we focus on the
features of whichever release of the OS we're testing, rather than the
behavior deltas between the releases.

If you have a more specific question about how an operation should behave,
please post it and I'll be happy to answer.

Have you tried copying the EFS-protected file onto a non-NTFS partition
or floppy (i.e., to FAT12/16/32 formatted media which don't support
EFS)?
 
You said "always TRIES to preserve the encryption state". This seems quite
notdefined behavior, so what are the exact circumstances, when the state is
NOT preserved?

Many thanks Ondra.

when the user selects the option to allow decryption either in a command
line flag, registry override or UI answer
