How to fix broken mov files​?

MOV files are widely used for storing video and audio content, primarily by Apple’s QuickTime. However, these files can become corrupted or broken due to various reasons such as improper file transfers, sudden power loss, software crashes, or malware infections. Fortunately, there are several methods to repair broken MOV files and restore them to a playable state.

Common Causes of MOV File Corruption

Interrupted File Transfer – A power outage or abrupt removal of storage media during file transfer can corrupt MOV files.

Bad Sectors on Storage Device – If the storage device contains bad sectors, files stored in those areas may become unreadable.

Unsupported Codecs – If a media player does not support the codec used in the MOV file, it may fail to play properly.

Virus or Malware Attack – Malicious software can corrupt or damage MOV files.

Incomplete Download – If a MOV file is partially downloaded due to network issues, it may be unplayable.

Software Crashes – Video editing software or media players crashing during playback or editing can lead to file corruption.
