What is file corruption? Why are files corrupted

Generally speaking, it is the file that is corrupted during the transfer process. It's possible that the network doesn't work, or you just disconnected it without finishing the transmission. Of course, it is also possible that it is bad before it happens.

Others may be small, such as a problem with your computer, a problem with your hard drive, or a problem with your USB flash drive. These have the potential to cause well, file corruption.

1. Not necessarily, if it is just an ordinary damage, it can be recovered, but at present, the fee for recovering files is relatively expensive, and some software that can repair files is also charged.

2. You can set the computer to display all files, there may be a hidden buffer file under the drive letter of your damaged file, open this file, and copy the data inside.

3. For many files, if they are not very important, it is not recommended to recover, first of all, it is a waste of time, and secondly, the charge is very expensive, which may not be necessary.

Generally speaking, recovering corrupted files requires a clear understanding of the structure of the file, but this is not an easy task and there are not many tools for this. However, if the bytes of the file are normal and cannot be opened properly, the file header is corrupted.

Generally, it is caused by the following reasons:

1. Caused by abnormal shutdown of the computer, such as sudden power failure.

2. Caused by accidental killing and deletion of security software. Posture shirts.

3. In the process of cleaning and setting, I am not familiar with the importance of the file, and I mistakenly deleted the search of the nuclear book.

4. Viruses in the computer cause file damage.

5. Part of the track of the computer disk is damaged.

Dear users, hello:

There are several reasons for this:

2) The RAR archive provided by the site.

It's inherently corrupted (there's no way around it, unless the package contains a reply record).

3) The ** tool used is not perfect, for example, after some ** tools open a few more threads, the finishing work of ** is very slow, and sometimes the data is no longer transmitted when ** to 99%, and it must be manually operated to end (stop first and then start again). I've been in this situation several times. As a result, the file is decompressed and decompressed to the end of the file, and the CRC error occurs.

Emergency solution 1Take advantage of recovery records.

If you want to repair CRC, there must be a recovery record in this RAR archive, and this recovery record is optional when the RAR archive is compressed.

However, the recovery record is not placed by default when WinRAR is compressed, and if such a RAR archive is provided, then it is impossible for the user to fix the CRC error by himself.

2.The bottom of the kettle is drawn.

If the files in the RAR archive are the kind of files that can be used normally or relatively normally even if the files are missing (in fact, most files are not very sensitive to some data corruption), then we can use our ultimate killer move: the bottom of the kettle!

The principle is to let the corrupted files in the RAR archive be decompressed, ignoring the warnings of winrar, and decompress as much as you can. The decompression software still uses winrar, but with a small setup.

In the window that pops up after right-clicking on the unzipped file, put the "Keep corrupted files" checkbox.

Select and click OK to start unzipping. Ignore the error message, you will find that the corrupted file has been extracted after the decompression is finished. The chances of the corrupted file being able to work properly after such decompression are still very high.

A little common sense. In fact, the solution to the error in the RAR archive is mainly based on prevention! If there is no prevention, when something really goes wrong, there is no way to solve it technically! Like cyclic redundancy checksums.

CRC) error, if the RAR compression package does not contain recovery records, it is impossible for the user to repair the CRC! The main purpose of this article is to tell you some of the causes of errors and discuss some ways to prevent them from making mistakes and minimize losses.

1) This prompt appears in the lower right corner of the taskbar (a file is damaged, please run to use the chkdsk tool to repair), it is generally caused by too many junk files in the system, mainly the junk files generated by the Internet, just clean it up.

Open a web page, click on the "Tools" menu on Internet Options under the "General" tab, click on "Delete cookies(i)", delete files pop-up, click on "OK" (including offline files), and restart the computer (no big problem, don't worry, no need to prompt the chkdsk tool). You can also use 360 Security Guard to clean up and optimize the system!

2) The system comes with the disk repair method: (if the mega stupid fault is still there, repair the disk, each disk is repaired) The specific steps are as follows: select the drive letter in My Computer Silly and right-click, and select it in the pop-up drive properties window.

Tools "Start Checking" and select "Automatically Fix File System Errors" and "Scan and Recover Bad Sectors", and then click Start, the scanning time will vary depending on the disk capacity and scanning options (after doing the above method, a box will pop up, the point is, repair after auto shutdown).

3) If it still doesn't work, it may be that there is a problem with the hard disk, try to repair it with software. Bad sectors on the hard drive will lead to corruption or loss of computer system files, computer failure to boot or freeze. Hard disk bad sectors can be repaired using NDD Disk Utility or Scandisk.

4) If the fault persists, please restore the system or reinstall it (it is still not possible to format the hard disk and repartition and reinstall it, if it doesn't work, you will have to replace the hard disk, or overhaul it).
