Summary: Have you noticed some files showing 0 bytes on your computer? What are they? How to open them? Today let iBoysoft help you with a brief introduction to 0 byte file.
In daily usage, files play a central role in storing and exchanging data. However, not all files contain information. Sometimes, you may notice that some files are completely empty, showing a size of "0 bytes".
These files are known as zero-byte files. Although they may seem insignificant at first glance, understanding the zero-byte file can help identify system issues.
What is a zero-byte file?
A zero-byte file is a file that exists within the filesystem but contains no data. It has a name and file metadata, such as creation date and permissions, but the file itself is devoid of any content. Such as:
- The file size is displayed as "0 bytes" in properties or file explorers.
- They have a valid filename and extension but cannot store any information.
- Zero-byte files can be found in any file format, including text files, images, or executables.
So are they useless? No. They can be used in development environments to reserve file names or test file handling functionality; Or utilized in scripts to signal certain actions or states.
How are zero-byte files created?
Why does my file say zero bytes? Zero-byte files can be created on your PC/Mac intentionally or unintentionally:
- Accidental creation: Software or system crashes during file-saving processes; Disruptions in file downloads or transfers, result in incomplete files.
- Corruption: Power outages, bad sectors on a hard drive, or malware can cause files to become zero bytes.
Now you must know some features of zero-byte files. Share this post with others.
How to create zero-byte files on Mac/Windows?
If you wanna create a zero-byte file on Mac or PC, it is so simple, you can follow:
Create a zero-byte file on Mac:
- Finder > Applications > Utilities > Terminal.
- Type the command touch filename.txt and press the Enter key.
(You can replace filename.txt with your wanted name.)
Create a zero-byte file on Windows:
- Click the Start menu, type cmd in the search box then click on Command prompt to open.
- Type the command type nul > filename.txt.

How to open or fix a zero-byte file?
Since zero-byte files contain no data, they cannot be "opened" in a conventional sense to view content. Programs will often display an error or a blank screen.
But we can fix or recover a 0-byte file. These ways can help you:
- Restore the original file from your backup.
- Use Disk Utility on Mac and CHKDSK on Windows to check and repair some issues.
- Recover with a professional tool like iBoysoft Data Recovery for Mac/Windows.
Final thoughts
While zero-byte files may appear to lack purpose, they are integral to various computing operations and can serve practical uses in specific contexts.
Understanding how they are created and managed ensures better control over your system. If you like our post, please share~
