Hi,

Many times when I try to recover files from a harddive they end up taking more space then the actual capacity of hard drive they was recovered from.

Example:

I have a hard drive with a total capacity of 160Gb. The files take up 89Gb (as stated in Windows properties). After the scan of the hard drive in ZAR and I select "all files" it states that the files require 191Gb. More then double the actual files size, and more space that was available on the source drive.

Before the recovery I selected ZAR to only backup "current" files from a "simple volume".

If there is a total of 89Gb I only want ZAR to recover 89Gb. Why does it show the double?

This is a known phenomenon, explained to certain extent in this thread (http://www.z-a-recovery.com/data-recovery-forum/showthread.php?t=276)
We cannot sort out good files from trash reliably. Additionaly, if NTFS compression was used on a volume, that also inflates the numbers.
