"Windows disk space running low issue"

When we buy a brand new personal computer, everything is taken care of by the vendor. We just use it. But, over time, our PC begins to slow down. The longer we use it, the more sluggish its performance becomes. With each Windows update, we are warned about “low disk space.” A system crash can happen suddenly, and wipe out hours of work.

The cause of all these issues is actually quite simple: uneven disk space distribution. This means that you have not resized your partitions properly, leaving some too big and others too small. Typically, your System C drive needs enough room to hold Windows files and updates. All of the problems mentioned above usually occur due to low disk space on the System C drive. Thankfully, you can use a partition tool to reallocate disk space. Here, I will focus on one method of extending a drive and maximizing your disk usage by merging partitions.

Free option 1: Windows Tool Kit

With Disk Management, you can adjust disk space with just a few mouse clicks.

If your system drive, C:, is running out of space and you have a data partition, D:, following it with a lot of free space, and you're running Windows 7, you can indirectly merge the partitions using the built-in Disk Management. First, copy all data from D: to another secure location, or back up all the data to an image file.

1. Right-click "My Computer" > select "Manage" > "Disk Management" > right-click on Drive D and select "Delete Volume".

2. Right-click on Drive C and select "Extend Volume," then incorporate the unallocated space into Drive C.

Alright, here's the translation in American English: Now you've successfully merged C drive and D drive. On one hand, this method is simple and free, requiring no professional skills. On the other hand, it does have its limitations. The cost of using the Windows tool is that you'll lose the other partition.

Free Option 2: Free Partition Merge Software - Tool - Partition Master Free Edition.

While Windows offers many options, they can be limited in what they can do. So when you find that the Windows toolkit isn't enough for your needs, it's time to turn to third-party partition software. Just remember to back up your data first. You might want to try the free and well-reviewed free partition manager, which works with any OS from Vista forward, including as a free Windows 10 partition manager that you can use to manage your new Windows 10 partitions right now.

This free software allows you to directly merge two adjacent partitions. Please refer to the tutorial below for details on how to merge partitions.

Step 1: Select the target partition.

Right-click the partition you want to merge more space into and select "Merge."

Step 2: Select the adjacent partitions to merge.

Merge with the partition that is next to the previously selected one.

Just click "OK" to proceed.

Next up, just translate the sentence into American English:

Step 3: Perform the merge partitions operation

1. Click the "Perform Action" button at the top of the screen, then click "Apply."
2. The program will merge the spaces and add the files from the second partition to the first one.
