[Bug-ddrescue] recover single files from NTFS partition?

[RD]

Hello,

Everything I read about ddrescue seems to imply trying to recover whole 
partitions. Can I also use it to recover single files from an otherwise 
good NTFS partition?

It's a 10 GB partition, and I don't have so much free space anywhere 
now. All I want is a couple of damaged email files of around 100 MB.

Can I mount the NTFS partition and "ddrescue /mnt/ntfs/my_mail_file 
logfile"? I understand the file may be not be laid out in one piece on 
the disk and may be fragmented.

In other words, I guess my real question is: does ddrescue copy disk 
blocks one after the other, or when given a file, does it just ask the 
filesystem module/driver/whatever to return the relevant blocks which it 
can read?


Thanks,

RD
