On a Windows 2016 server, I deleted the contents of the recycle bin which I believed had around 100GB of data. The server has a 1.5TB drive with some parts being used for file shares and historic versions. However, after emptying the bin, I noticed that the amount of free space on the drive had increased by approximately 200GB, which was twice the amount I had expected.
I’m not sure if there’s a reasonable explanation for this, or if I’m just imagining things due to excessive caffeine consumption.

Introduction
In this blog post, we will be discussing the possible reasons why emptying the recycle bin on a Windows Server 2016 can create more room than planned. We will explore the different factors that can affect the amount of free space on a drive and how to properly manage your disk space.
Recycle Bin and Disk Space Management
The recycle bin is a feature in Windows that allows users to recover deleted files. When a file is deleted, it is not permanently removed from the system but instead moved to the recycle bin. The user can then restore the file if needed or empty the recycle bin to permanently delete the file. However, emptying the recycle bin does not always result in the expected amount of free space on the drive.
One possible reason why emptying the recycle bin can create more room than planned is that there may be hidden files or folders that are taking up space on the drive. These files may not be visible to the user but are still present on the system. Emptying the recycle bin removes these hidden files and frees up space on the drive.
Another reason why emptying the recycle bin can create more room than planned is that there may be temporary files or system files that are no longer needed. These files can accumulate over time and take up valuable disk space. Emptying the recycle bin removes these unnecessary files and frees up space on the drive.
File Compression and Deduplication
Windows Server 2016 also includes features such as file compression and deduplication that can affect the amount of free space on a drive. File compression reduces the size of files by compressing them into a smaller format. This can result in significant space savings, especially for large files such as videos or images.
Deduplication is another feature that can reduce the amount of space used on a drive. Deduplication identifies duplicate files and removes them, leaving only one copy of the file on the system. This can result in significant space savings, especially for files that are frequently duplicated such as backups or virtual machine images.
Storage Spaces
Windows Server 2016 also includes a feature called Storage Spaces that allows users to create virtual disks that span multiple physical drives. This can be useful for managing large amounts of data and can also provide redundancy in case of drive failures.
However, Storage Spaces can also affect the amount of free space on a drive. When a virtual disk is created, a certain amount of space is reserved for overhead, which can reduce the amount of free space on the physical drives. Additionally, if a drive in the Storage Space fails, the remaining drives may need to be rebuilt, which can also reduce the amount of free space on the drives.
Disk Cleanup and Defragmentation
To properly manage disk space on a Windows Server 2016, it is important to regularly perform disk cleanup and defragmentation. Disk cleanup removes unnecessary files and temporary files from the system, freeing up valuable disk space. Defragmentation reorganizes the files on the drive, making them easier to access and improving system performance.
Disk cleanup and defragmentation can also affect the amount of free space on a drive. Disk cleanup can free up space by removing unnecessary files, while defragmentation can free up space by reorganizing the files on the drive. However, both disk cleanup and defragmentation can take a significant amount of time to complete, especially on large drives.
Conclusion
In conclusion, emptying the recycle bin on a Windows Server 2016 can create more room than planned due to various factors such as hidden files, temporary files, file compression, deduplication, Storage Spaces, disk cleanup, and defragmentation. Properly managing disk space on a Windows Server 2016 is essential to ensure optimal system performance and prevent data loss due to drive failures. By regularly performing disk cleanup and defragmentation, and utilizing features such as file compression and deduplication, users can effectively manage disk space and ensure their systems are running smoothly.
There are a few possible explanations for why emptying the recycling bin on a Windows Server 2016 machine would result in more free space than expected:
- The recycling bin may have contained multiple copies of the same file, resulting in the space being freed up multiple times when you emptied the bin.
- The recycling bin may have contained hard links to the same file, which would cause the space to be freed up multiple times when you emptied the bin.
- There may have been other files or folders in the recycling bin that were taking up space, but were not visible to you.
- There may have been hidden system files in the recycling bin that were taking up space, but were not visible to you.
- There may have been a problem with the way the free space on the drive was being reported, causing it to appear that more space was freed up than actually was.
It’s also possible that you simply made a mistake in your calculations and the recycling bin did not actually contain as much data as you thought it did.
Without more information, it’s difficult to say for certain what might be causing the unexpected increase in free space. It’s always a good idea to double-check your calculations and make sure that you’re not missing any hidden files or folders that might be taking up space.
In conclusion, there are a few possible explanations for why emptying the recycling bin on a Windows Server 2016 machine might result in more free space than expected. These include the presence of multiple copies of the same file, hard links to the same file, hidden system files, or a problem with the way the free space on the drive is being reported.
It’s also possible that you simply made a mistake in your calculations and the recycling bin did not actually contain as much data as you thought it did. To troubleshoot this issue further, it might be helpful to use a tool like TreeSize or WinDirStat to see a breakdown of where the space on your drive is being used, and to check for any hidden or system files that might be taking up space.
WindirStat displays the total size of data, not the total amount of allocated space. This is evident from the fact that the most commonly used allocation unit on NTFS is 4KB, while the sizes shown by WindirStat are not multiples of that amount.
The final sector of a file is allocated only for that particular file, and the actual size of the file is rounded up to the allocation unit.
If you have many small files, then you may end up reclaiming much more space than the total size of your data, as the loss of space due to the allocation unit is maximized.
