copying preserving packed os attribute

[Hurdet]

When i copy a file packed from OS the destination loss the packed attribute.
Do it is possible to preserve it with TC and/or dos?

No, that's not how the Windows CopyFileEx function behaves. It copies the file depending on the attribute of the target FOLDER: If the target folder has the "compressed" attribute set, all files copied to it will also have this attribute. Otherwise they will be uncompressed.

I have un folder A that set with compact.
I Junction other folder B not compacted.
I then see that B is not compacted and A is compacted.
Do it is normal?
A not is only a reference to B without news file copy in hard disk?

A Junction is just a special kind of link to a folder.
The Junction itself is not compacted, but it points to the same files, which are still compacted.

I understand this, and that is what I would expect.
But instead, if you read well, happens to me that the folder originally uncompressed when it copy to compressed drive is compressed in the target remaining in the uncompressed source.

If you copy/move file with compression and/or encryption attributes onto FAT32 drive, it will lose those atributes because FAT32 doesn't support those.
Also, if you copy files from NTFS to NTFS, they won't transfer the attributes, you have to MOVE them. Only with moving they will keep the 'compressed' attribute.
