TC 6.03a incorrect copy operation on EFS encrypted files

[olego]

This has been verified using the latest available version of TC (6.03a) on Microsoft Windows XP.

-= Destination file loses encryption =-

To repro:
1) Create an encrypted file on NTFS volume;
2) Using TC, copy this file into another directory on the same volume;

Expected: the destination file to stay encrypted (as it happens when copying is performed with Explorer or by command line utilities 'copy', 'xcopy', etc);
Actual: the destination file is copied unencrypted.

-= When copying encrypted file to a file system not supporting encryption, file gets copied unencrypted without warning dialog box =-

To repro:
1) Create an encrypted file on NTFS volume;
2) Using TC, copy this file into any directory on FAT volume;

Expected: before actual copying the warning dialog box to appear notifying that destination file is going to be unencrypted (as it happens when copying is performed with Explorer, 'copy', 'xcopy', etc);
Actual: the file is copied silently, without any warnings. The destination file loses encryption.

Thank you.
