Если файлы были зашифрованы то их необходимо расшифровать, сделать это можно программой Advanced EFS Data Recovery
Advanced EFS Data Recovery (or AEFSDR) is a program to recover (decrypt) files encrypted on NTFS (EFS) partitions created in Windows 2000, Windows XP and Windows Server 2003. Files are being decrypted even in a case when the system is not bootable and so you cannot log on, and/or some encryption keys have been tampered. Besides, decryption is possible even when Windows is protected using SYSKEY. AEFSDR effectively (and instantly) decrypts the files protected under all versions Windows Server 2003 (Standard and Enterprise), Windows XP (including Service Packs 1 and 2) and Windows 2000 (including Service Packs 1, 2, 3 and 4).
New in version 3.0:
Wizard has been implemented
seriously improved key decryption speed
improved file decryption speed: in 60 times for AES, in 11 times for DESX
decrypting files that are larger than 4Gb
added support for NTFS disks with MFT size other than 1024 bytes
complete support for UNICODE systems (like Chinese and Japanese)
