What does 0 bytes mean?

Bytes serve as a crucial unit of measurement, revealing the size of a file or the space occupied on a drive. A reading of 0 bytes signifies an absence of data – an empty file or an empty drive.

Nevertheless, a 0-byte reading doesn't always equate to true emptiness. It could be a misleading reading caused by a drive-related problem. When a folder displays 0 bytes despite containing data you know is there, it's a clear indicator of an underlying issue.

Possible reasons for a 0 bytes drive

Multiple factors can cause a hard drive to show 0 bytes. Please get an overview of the following common reasons.

📮 No space: A disk may read 0 bytes remaining when there's insufficient storage space to accommodate additional data. In such instances, a straightforward solution involves deleting unnecessary data or upgrading your storage capacity.

🧨Corrupted file systems or bad sectors: The corruption of a file system has the potential to disrupt your computer’s boot process and result in a drive displaying 0 bytes.

🎆 Viruses or malware: In such scenarios, the presence of a 0-byte virus may have infiltrated your computer, causing your files, folders, or disk to exhibit a 0-byte reading. Thankfully, this issue can often be resolved by conducting a thorough antivirus scan on your system.

💻 Improper shutdown: Abruptly shutting down your computer before it completes a critical operation can result in both data and file system corruption.
