Requires clarification on accessing snapshot files

I have Linux 64 bit VM. I have enable CTK and then taken a snashots.I have taken about 5 snapshots before that and deleted all.

Now by calling QueryDiskChangedArea("*") got a vector of offset to write and i did active blocks written to destination VM.I used base disk to open and write it.

When i power on the vm its showing the old files. New files whatever i copied between the snapshot creation and deletion is not showing.

Siva, you told that once we delete the snashot all the containts will be merged to base disk.If i power off the VM and open the current snapshot file and write it , its seems to be working.

Need a clarification on the steps.Can some one please clarify this.

with thanks,

Santosh
