How is it possible that after i moved some files from one server to another that it spikes in size.

Question

I need to clear a few things up. We needed to move a handful of files which is around 200gb.

however after copying them to the new server, it went from using 200gb to 320gb. Which is weird.

The only clue i might have is that the old server says Size 202gb and Size on disk 202gb, where as the new one says Disk 202gb and Size on disk 169gb. Which should suddenly take up 320gb of a 400gb shared drive.

Answer 1

We found out what the problem was, the drive was fragmented. We don't how since we never told the drive to do it, plus it's a virtual drive.

otherwise thanks for the support.

Answer 2

Hello,

Thank you for your post on the Microsoft Forum.

Can you describe this issue in more detail? Because this makes it easier for us to locate the problem, such as how you copied the files and what kind of data files were newly added to the disk after the copying was completed.

Best regards

The way the files are moved is from a physical drive to a drive on virtual machine in vmware. the files is a mix of different things but mostly .iso files.

The way i'm able to move them from one server to another is by mapping the drive of one machine over the network and then drag and dropping the files onto the new drive.

I have checked the folder multiple times, yet i don't seem to find anything that just adds itself.

Hi,

You can download two tools PSTools.zip and TreeSizeFreeSetup.exe from the following link, copy them to the machine in question and decompress them. This tool can check the space occupied by each folder on the disk.

The download link is as follows:

PsTools - Sysinternals | Microsoft Learn

After the installation is complete, run CMD as administrator and run the following command:

cd pstools path

psexec -s -i "treesize path"

The purpose is to open the Treesize tool with system permissions and view the disk space usage.

In the treesize console, click select Directory and select the disk you want to view:

size is the current disk space occupied by the corresponding file. We can try clicking the "+" next to the folder on the far left to view files that take up larger space:
