File corruption can be repaired, but it depends on the situation. First, confirm whether it is an opening method or software version problem. Secondly, try the system's own repair functions such as Word's "Open and Repair" or Windows' chkdsk tool; if it is invalid, you can scan and repair professional data recovery software such as Recuva, EaseUS Data Recovery Wizard, etc.; at the same time, pay attention to preventive measures such as regular backups, using antivirus software, correctly ejecting the USB flash drive, etc. to avoid file corruption.
File corruption is really annoying, especially when you are in a hurry to use it. Sometimes the files can be saved, but it depends on the situation and method.

Check if it's really bad
Sometimes you think the file is broken, it may be just the way to open it wrong or the software version is too old. For example, if the Word file cannot be opened, try changing the version, or drag it to the online preview website to see if it can be read. If it is a picture or video, changing the player or decoder may also solve the problem.

Several common situations:
- The file extension has been changed (for example, from .docx to .txt)
- The program reported an error saying "Unrecognized format"
- After opening the content, the garbled code will be displayed
Try the system's own repair function
Many office software, such as Microsoft Office or WPS, have built-in file recovery tools. Take Word as an example:

- Open Word
- Click "File" > "Open"
- Find the damaged document, click the drop-down arrow, and select "Open and Repair"
If it is Excel or PPT, the operation is similar. This method doesn't necessarily work every time, but it's worth a try.
In addition, the command line tool chkdsk
which comes with Windows, can sometimes fix file corruption caused by disk errors, but this requires a certain operating basis and is not recommended for novices to run it casually.
Use professional tools to scan and repair
If the conventional method does not work, you can consider using data recovery software, such as Recuva, EaseUS Data Recovery Wizard, or DiskDigger. These tools can scan the hard drive to find "lost" file fragments, suitable for cases where errors are deleted or minor corruption.
A few things to note when using this type of tool:
- Operation as soon as possible, the earlier the better, to avoid data overwriting
- Do not install it on the same partition to avoid affecting the recovery effect
- The recovered file is not necessarily complete, it may require multiple attempts
There are also some repair tools specifically for a certain file type, such as R-STUDIO (suitable for various files), PhotoRec (mainly photos), etc., which can also be selected according to the specific situation.
Prevention is more important than repair
In fact, many times the file corruption is caused by sudden power outage, forced U disk removal, program crashes, etc. Therefore, it is important to develop good habits in daily life:
- Back up key files frequently
- Use reliable antivirus software to prevent virus damage
- Confirm that the saving is completed before closing the file
- Remember to "securely eject" before unplugging the USB drive or mobile hard drive
Basically that's it. Don’t panic when you encounter the file corruption. First judge the situation and then deal with it step by step. In many cases, you can still rescue it.

The core of artificial intelligence is algorithms, especially models that can learn laws from data, such as deep learning. It trains the system through a large amount of data, allowing it to make judgments on new situations, such as face recognition and chatbots. AI is not really intelligent, but statistical methods that mimic human behavior. Common applications include voice recognition (such as Siri), image recognition (such as Alipay face-scanning payment), recommendation systems (such as TikTok and Taobao recommendations), and autonomous driving. AI's capabilities have boundaries, it can only work within the scope of training data, has no real awareness, and relies on a large number of computing resources. When looking at AI, it should be rational. It is an efficient tool but not perfect. It can be used to improve efficiency, but it also needs to be wary of its limitations.
