Merge two Windows partitions

Today we would like to show you how you can merge two partitions or volumes relatively easily and thus have a larger partition with more storage space afterwards. This process is actually relatively simple, but there are a few things to consider when merging the paritions .

Let’s assume that we have 2 partitions on a hard disk (HDD or SSD), which we now want to merge into one volume . In this case, the prerequisite is that the second partition or volume is empty, because this volume must be deleted.

Attention: We would like to point out that prior to such Windows system changes, an up-to-date backup of the entire data should be available if problems arise. 

As you can see below, we want to merge volumes E: and F: so that we have a large partition afterwards. To do this, we first backed up all data on volume F: and moved it to another volume. Volume F: is now empty and can be used in the disk management (diskmgmt.msc)

Delete volume …

to be deleted.

Merge volumes and delete free volume

Before Windows really deletes the volume, the following security question appears .

Delete volume

This security question is:

Deleting the volume deletes all data on it. Back up any files you want to keep before you start deleting. Do you want to continue.

After deleting the partition , the previously used space on the data carrier is released again. Now you can simply expand the existing volume with the following function.

Extend volume…

Extend volume

Now you will be guided through the expansion of the volume with an assistant . You have to specify by how much storage space the existing partition should be expanded .

By default, Windows suggests the total free space available.

Expand Volume Wizard

If you have now successfully completed this extension wizard, the existing partition has all the space available on this data carrier.

Volume merged

This makes it relatively easy to merge two partitions or volumes.
