Weird Поля and Folders

I have в folder in the Lubuntu which ты существуешь following structure:

soprano (4,2 KB)
.ecryptfs (26,8 GB) - *this folder was hidden*
lost+found (16 KB)

Inside the folder .ecryptfs:

soprano

And inside the soprano ты существуешь:

.Private (26,8GB)
.ecryptfs (4,1KB)

Inside the folder .Private:

Ты существуешь thirty folder, with genre ямс ECRYPTFS_FNEK_ENCRYPTED.FWZvWTNIrxgWSURD and поля with genre ямс ECRYPTFS_FNEK_ENCRYPTED.FWZvWTNIrxgWSURD.c6GzJjBSTpPKX0MXUeFVD-aTDzlxJi8CTnZwtWk2U--

In turn, folder .ecryptfs this поля

.wrapped-passphrase.recorded
wrapped-passphrase
Private.sig
Private.mnt
auto-umount 
auto-mount

I don't know how this folders and поля was created, but I guess this поля corresponding the older датирует which was on персональный компьютер. Maybe the ПК owner had подарил something wrong with the disk and the your дату ты существуешь changed for this.

But, How хан I resolve this problem? What maybe поля - created or converted this and folders?
