The documented Windows feature is the CreateHardLink Win32 API and the fsutil hardlink command. Treat a file with this name as an unverified third-party program until you inspect its location, signer, hash, and origin.
The name may appear while a backup, synchronization, development, storage, or installer program creates hard links. It can also belong to an unwanted or damaged application. Do not delete or replace it solely because the filename looks unfamiliar. First preserve the exact error, identify the file, and then test the file-system conditions that hard links require.

What a Windows hard link is
A hard link is a second directory entry for the same underlying file data. Both names refer to the same file; neither is a separate copy. Microsoft describes CreateHardLink as establishing a hard link between an existing file and a new file.

- They link files, not directories.
- Deleting one name does not delete the file data while another hard-link name remains.
- Microsoft documents a maximum of 1,023 hard links for one file.
Windows programs can open a hard link as they would any other filename. The link is not a shortcut and does not contain a separate target path in the way a shortcut does.

What createhardlinks.exe might be
The filename suggests a utility that creates hard links, but the name alone proves nothing about its publisher or purpose. It could have been installed with a legitimate backup, synchronization, source-control, storage, or deployment application; it could be a damaged component; or it could be an unwanted executable using a plausible name. The exact publisher, version history, and intended function cannot be established without evidence from the affected computer.
Microsoft documents the API and command-line facility, not a standard executable named createhardlinks.exe. That distinction matters: a valid Windows hard-link operation does not make every program with “createhardlinks” in its name trustworthy.
Is createhardlinks.exe a virus?
There is no sound way to classify a particular copy as safe or malicious from its filename. Use several independent checks instead:
The Tool Desk
Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →1. Check the complete path
In the error dialog, Task Manager, or the program that reported the failure, record the complete path, including the drive letter. A file inside a known application’s installation directory is easier to explain than one in a random temporary, downloads, or user-profile subdirectory, but location is not proof of safety.
2. Inspect the digital signature
- Right-click the file and choose Properties.
- Open Digital Signatures, if that tab exists.
- Select a signature and choose Details.
- Confirm that Windows reports the signature as valid and that the publisher matches the application you installed.
An absent or invalid signature does not automatically prove malware, because some legitimate utilities are unsigned. It does mean you should require stronger evidence from the file’s origin and a security scan.
3. Calculate and scan the hash
Record a cryptographic hash before moving or deleting the file. In PowerShell, run:

Get-FileHash -LiteralPath "C:pathtocreatehardlinks.exe" -Algorithm SHA256
Submit the resulting hash, or the file where your organization permits it, to an established malware-scanning service or your managed endpoint-security system. Review the result from Microsoft Defender or the security product your organization uses. A clean result is useful evidence but is not a guarantee; a detection should be handled according to your security policy.
4. Identify the installing application
Ask what changed immediately before the message appeared. Look at recently installed programs, backup jobs, synchronization clients, developer tools, storage utilities, and scheduled tasks. Record the exact application name and version, the executable path, and the complete error text. This context is often more useful than the filename.
5. Do not download a replacement executable
Do not obtain a “replacement DLL” or executable from an unverified download site. If the file belongs to a trusted application, repair or reinstall that application from its official publisher instead.
Can you delete createhardlinks.exe?
Do not delete it until you know which application owns it. Removing a component while its parent program is running can cause repeated errors, failed backups, or data-operation failures.
If the file is unwanted or unsigned
- Disconnect from networks or follow your organization’s incident procedure if a security product reports a threat.
- Use Windows Security or managed endpoint protection to quarantine the file.
- In Settings > Apps > Installed apps (or Apps & features on older Windows), remove the parent application if you can identify it.
- Use the vendor’s uninstaller when one is provided.
- Restart and run a fresh security scan. Keep the original path, hash, and detection details for troubleshooting.
If it belongs to a trusted application
Leave the executable in place and repair or reinstall the owning program from its official source. Update that program and retry the operation that failed. A missing or damaged file is normally fixed by restoring the complete application, not by copying an executable from another computer.
If Windows reports the file is in use
Close the related application and its background processes. If necessary, restart Windows and perform the repair before launching the program again. Do not force-delete a file that an active backup or synchronization job may still need.

Why hard-link operations fail
An error attributed to createhardlinks.exe can reflect the program itself, Windows permissions, or a hard-link constraint. Before changing files, write down the source path, destination path, drive letters, file-system type, account used, exact command, and numeric Windows error code.
Unsupported file system
Microsoft documents CreateHardLink for NTFS. A source or destination on a file system that does not support the operation can fail even when both paths look valid. Check each volume in File Explorer: right-click the drive, choose Properties, and read the File system value.
Different volumes
The existing file and the new hard-link name must be on the same volume. C:Datafile.bin and D:Archivefile.bin cannot be hard-linked because the drive letters identify different volumes. Use a same-volume destination or choose a symbolic link or ordinary copy when crossing volumes is required.
Recommended Free Tools
Directories instead of files
Hard links are for files, not directories. A program that passes a folder path to a hard-link API will fail. Confirm that the source is a regular file and that the destination is intended to be a filename, not a directory.
Destination already exists
The new link name normally must not collide with an existing file or directory. Check the destination with File Explorer or PowerShell, and preserve any existing data before renaming or removing it.
Invalid, inaccessible, or overly long paths
Typos, deleted source files, malformed path syntax, unavailable network locations, and path-length limitations can all produce a failure. Copy the paths directly from the application’s log where possible. Confirm that the source opens, the destination directory exists, and the account can read the source and create entries in the destination folder.

Permissions and sharing
The account needs access to the source and destination directories. Another process may also have the file open with sharing restrictions. Close applications that use the file, retry from an account authorized for both locations, and check whether endpoint-security controls or controlled-folder policies are blocking the write.

Symbolic-link input
Microsoft documents that when a path is a symbolic link, CreateHardLink creates a hard link to the target. This can produce a result different from what an operator expects if the source path is itself a link. Resolve the path and verify the target before creating another link.
How to inspect existing hard links
Windows includes the documented fsutil hardlink commands. Open Windows Terminal or Command Prompt, then run:
fsutil hardlink list "C:pathtofile.ext"
The command lists directory entries that are hard links to the specified file. Use the output to determine whether another name still preserves the data before removing one entry.
To create a hard link deliberately, the syntax is:
fsutil hardlink create "C:same-volumenew-name.ext" "C:same-volumeexisting-name.ext"
Use this only after confirming that both paths are files on the same NTFS volume and that the destination name does not already exist. A successful command creates another name for the same data; it does not copy the file.
Manual workflow for a createhardlinks.exe application error
- Capture evidence. Screenshot or copy the exact dialog, numeric error code, executable path, source path, destination path, and time of failure.
- Stop repeated failures. Pause the backup, synchronization, or installer job so it does not continually modify the same files while you diagnose it.
- Identify ownership. Check the executable’s folder, installed-program list, scheduled tasks, and the application log that launched it.
- Verify trust. Inspect the signer, calculate a SHA-256 hash, and scan with Windows Security or your managed security tooling.
- Validate the file operation. Confirm NTFS, one volume, regular files, valid paths, a free destination name, and permissions for the account running the job.
- Inspect links. Run
fsutil hardlink liston the source file and preserve the output. - Repair the owning program. Use its official repair option or reinstall it from the publisher if the executable is damaged or missing.
- Retry with a test file. Reproduce the operation on a non-critical file in a test directory on the same NTFS volume before touching production data.
- Escalate with complete data. Give the application vendor or administrator the exact paths, error code, Windows edition, file-system details, signature status, hash, and steps that reproduce the problem.
What to do when createhardlinks.exe is missing
A “missing” message does not mean Windows itself requires this filename. It usually means an installed application is trying to launch a component that was removed, quarantined, renamed, or corrupted.

Hard link, symbolic link, or shortcut?
These mechanisms are not interchangeable. Choose based on the behavior you need:
| Feature | Hard link | Symbolic link | Windows shortcut |
|---|---|---|---|
| References the same file data | Yes; each name is a directory entry for the same file | References a target path | Stores a shell shortcut to a target |
| Can cross volumes | No; all names must be on one volume | Yes, subject to target availability and permissions | Yes, if the target path is reachable |
| Directories supported | No | Yes | Can point to a directory |
| Effect of deleting one name | Other hard-link names continue to access the data | The link can become broken if its target is removed or moved | The shortcut can become broken if its target is removed or moved |
Use a hard link when same-volume file identity is intentional. Use a symbolic link when a path reference or cross-volume target is required. Use a shortcut for a human-facing shell entry rather than for file-system semantics.
Common mistakes to avoid
- Assuming “Microsoft” or “Windows” in a filename proves origin.
- Deleting the executable before recording its path and error details.
- Trying to hard-link a directory.
- Using source and destination paths on different drive volumes.
- Replacing a missing file with a download from an unverified executable site.
- Testing repairs on irreplaceable data instead of a non-critical file.
- Ignoring the parent application’s logs and focusing only on the Windows filename.
- Confusing a hard link with a shortcut and expecting it to work across volumes.
When the evidence is still inconclusive
If the signature, hash, path, and origin do not produce a consistent explanation, do not label the file safe or malicious prematurely. Preserve the file in quarantine or an approved evidence location, record the hash and timestamps, and ask your security administrator or the owning application’s support team to review it. The exact publisher and intended function of createhardlinks.exe remain machine-specific.

Frequently Asked Questions
Is createhardlinks.exe a standard Windows file?
No standard Windows executable with that exact name is identified in Microsoft’s documentation. Microsoft documents the CreateHardLink API and fsutil hardlink command instead.
Can I safely delete createhardlinks.exe?
Only after identifying its parent application and checking its signer, hash, and security status. Remove an unwanted file through Windows Security and the parent application’s uninstaller; repair or reinstall it if it belongs to trusted software.
Why does a hard-link command fail between C: and D:?
Hard links must keep both names on the same volume. Paths on C: and D: are normally different volumes, so use a same-volume destination or another link type.
How do I list every hard link for a file?
Run fsutil hardlink list “full\path\to\file” in Windows Terminal or Command Prompt.
