In space critical disk, I seen that the deployed disks have less free space than the original disk used to create disk image, about 320MB less in 2GB disk.

This happens using R-Drive 6.1 on a Windows 7 desktop computer, source or target disk connected to it by an USB 3.0 adapter; I seen that in the System Volume Information folder of the cloned disk appears a strange file having size of 320MB. This one there is not in the "master" disk.
It seems that is the image generated from the Master disk that have inside the undesired file.

Making the same work on a Windows XP computer, this trouble does not happens.

What is the name of the file?

The file have name 5{3808876b-c176-4e48-b7ae-04046e6cc752}
The O.S. of the deployed disks is Windows Embedded Standard.

Thank you.
