Corrupted files don’t happen too often on modern computers with good security measures in place. But when they do, it can be a nightmare. Let’s take a look at the common causes of corrupted files, how you can help prevent them, and what you can do when it happens.
Why Do Files Become Corrupted?
![Idm Is Corrupted Virus Idm Is Corrupted Virus](/uploads/1/2/3/7/123703572/254073464.jpg)
Usually, files become corrupted when being written to a disk. This can happen in various ways, the most common of which is when an app suffers an error while saving or creating a file. An office app might suffer a glitch at the wrong time while saving a document. A compression app may experience problems while creating an archive. Your backup app may have problems when writing out your backup. Your browser (or other download app) may even have problems writing a downloaded file to disk.
Often, these apps will notice the error and let you know that something went wrong, giving you the chance to try again. Sometimes, though, you’ll have no idea that something went wrong until you try to open the file later.
There are, of course, other reasons that files can become corrupt, as well.
When you shut down your computer, it is supposed to close out any files it has open properly (or give you the chance to do so). When this doesn’t happen—like, say, if you lose power or if your computer crashes—it doesn’t have the chance to close files the right way. This can lead to the corruption of any files that were currently open, including not just your documents, but even operating system files.

Problems with your hard disk can also lead to corrupted files. Sometimes, like in the case of a bad physical sector on the drive, your corrupted file may be part of a much larger problem. Sometimes, smaller errors—like a cross-linked file or lost cluster—are the culprit in your file corruption problems and are not necessarily indicative of a failing hard disk.
And finally, of course, malware and viruses can also cause corruption, though in that case, it’s more intentional than accidental.
How to Protect Against Corrupted Files

RELATED:What’s the Best Way to Back Up My Computer?
First and foremost, the single best thing you can do to protect yourself against corrupted files is make sure you’re backing your computer up regularly. And note that cloud storage and other file syncing options may not be enough to get the job done. If you have a corrupt file on your local disk that then gets synced to your cloud storage, you don’t really have a good backup of that file. If you do rely on cloud storage, at least make sure that you have the option to recall previous versions of files (like in Dropbox).
It’s always best to use a true backup solution like File History (on Windows), Time Machine (on macOS), or Backblaze, all of which allow you to restore multiple previous versions of files.
Next up on the prevention checklist, make sure that your computer is protected from viruses and malware. This includes not only running a good antivirus app, but using common sense when browsing and downloading.
RELATED:How to Select an Uninterruptible Power Supply (UPS) for Your Computer
And finally, you might want to consider investing in an uninterruptable power supply (UPS) to help protect your computer from sudden shutdowns when you lose power. A UPS works as a battery backup that provides you a buffer against power loss. Typically, they can supply your computer with anywhere from a few minutes to an hour or more of power, giving you ample time to shut your computer down properly. Having a good UPS can not only help prevent corrupted files from a bad shutdown, but the hardware problems they can cause, as well.
What Can You Do When a File Is Corrupted?
If you have a corrupted file, your best bet is to try grabbing that file from the source again. Download it again, if that’s where you got it, or have someone resend the file to you.
RELATED:How to Repair Corrupted Windows System Files with the SFC and DISM Commands
In the case of corrupted system files (from an unexpected shutdown, bad update, or malware), you can always try something like Windows’ built in System File Checker. It scans your system for corrupted system files, and then replaces them with originals.
Before you do that, though, it’s best to try fixing the cause of the problem. In the event of malware, you should first make sure you’ve removed that malware from your computer. If you suspect a bad update caused the problem, you might be able to roll that update back.
If your corrupted file is a document that you’ve created, unfortunately, your options are limited. Some apps (like those included with Microsoft Office) autosave multiple versions of your document, letting you open a previous version if the current version becomes corrupt.

If you don’t have the luxury of opening a previous version, you may be able to repair the file or, at the least, recover the text from it. Again, Microsoft Office apps offer built-in tools for recovering lost or corrupted documents, as do some other programs. Even if you can only recover the text from a document, you can save a lot of time when recreating the file.
There are also a number of apps out there that claim they can recover different types of corrupt files. Some are free and some are paid, but the truth is, most don’t work very well. And a few that we tested were bloated with companion apps or, worse, malware. Given that, we recommend just not using them.

How To Fix Internet Download Manager Error 0x80029C4A
Below is a list of troubleshooting steps to resolve your Error 0x80029C4A problems. These troubleshooting steps get progressively more difficult and time consuming, so we strongly recommend attempting them in ascending order to avoid unnecessary time and effort.

Step 1: Repair Registry Entries Associated with Error 0x80029C4A |
Manually editing the Windows registry to remove invalid Error 0x80029C4A keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely! Because of this risk, we highly recommend using a trusted registry cleaner such as WinThruster [download] (Developed by Microsoft Gold Certified Partner) to scan and repair any Error 0x80029C4A-related registry problems. Using a registry cleaner [download] automates the process of finding invalid registry entries, missing file references (like the one causing your 0x80029C4A error), and broken links within the registry. A backup is automatically created before each scan, with the ability to undo any changes in a single click, protecting you against the possibility of PC damage. The best part is that repairing registry errors [download] can also dramatically improve system speed and performance. Caution: Unless you an advanced PC user, we DO NOT recommend editing the Windows registry manually. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. We do not guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to Error 0x80029C4A (eg. Internet Download Manager):
The next steps in manually editing your registry will not be discussed in this article due to the high risk of damaging your system. If you would like to learn more about manual registry editing, please see the links below. We do not claim any responsibility for the results of the actions taken from the content linked below - complete these tasks at your own risk. Windows XP http://www.theeldergeek.com/windows_xp_registry.htm Windows 7 http://www.theeldergeek.com/windows_7/registry_edits_for_win7.htm Windows Vista http://support.microsoft.com/kb/2688326 - LetMeFixItMyselfAlways |
Step 2: Conduct a Full Malware Scan of Your PC |
There is a chance that your 0x80029C4A error could be related to a malware infection on your PC. These malicious intruders can damage, corrupt, or even delete Runtime Errors-related files. Furthermore, there's a possibility that the 0x80029C4A error you are experiencing is related to a component of the malicious program itself. Tip: If you do not already have a malware protection program installed, we highly recommend using Emsisoft Anti-Malware (download here). They offer a malware removal guarantee that is not offered by other security software. |
Step 3: Clean Out Your System Junk (Temporary Files and Folders) With Disk Cleanup (cleanmgr) |
Over time, your computer accumulates junk files from normal web surfing and computer use. If this junk isn't occasionally cleaned out, it can cause Internet Download Manager to respond slowly or provides an 0x80029C4A error, possibly due to file conflicts or an overloaded hard drive. Cleaning up these temporary files with Disk Cleanup might not only solve your 0x80029C4A error, but can also dramatically speed up the performance of your PC. Tip: Although Disk Cleanup is a wonderful built-in tool, it will not completely clean up all of the temporary files on your computer. Other programs that you frequently use such Microsoft Office, Firefox, Chrome, Live Messenger, and hundreds of other programs are not cleaned up with Disk Cleanup (including some Tonec Inc. programs). Because of the shortcomings of the Windows Disk Cleanup (cleanmgr) tool, we highly recommend using a specialized hard drive cleanup / privacy protection software such as WinSweeper [download] (Developed by Microsoft Gold Partner) to clean up your entire computer. Running WinSweeper [download] once per day (using automatic scanning) will ensure that your computer is always clean, running fast, and free of 0x80029C4A errors related to temporary files. How to run Disk Cleanup (cleanmgr) (Windows XP, Vista, 7, 8, and 10):

Step 4: Update Your PC Device Drivers |
0x80029C4A errors can be related to corrupt or outdated device drivers. Drivers can work one day, and suddenly stop working the next day, for a variety of reasons. The good news is that you can often update the device driver to fix the Error 0x80029C4A problem. Finding the exact driver for your Error 0x80029C4A-related hardware device can be extremely difficult, even directly on the Tonec Inc. or related manufacturer's website. Even if you are experienced at finding, downloading, and manually updating drivers, the process can still be very time consuming and extremely irritating. Installing the wrong driver, or simply an incompatible version of the right driver, can make your problems even worse. Because of the time and complexity involved in updating drivers, we highly recommend using a driver update tool such as DriverDoc (Developed by Microsoft Gold Partner) to automate the process. DriverDoc updates all of your PC device drivers, not just those associated with your 0x80029C4A error. DriverDoc's proprietary One-Click Update™ technology not only ensures that you have correct driver versions for your hardware, but it also creates a backup of your current drivers before making any changes. Maintaining a driver backup provides you with the security of knowing that you can rollback any driver to a previous version if necessary. With updated device drivers, you can finally unlock new hardware features and improve the speed and performance of your PC. Please Note: Your Error 0x80029C4A may not be related to hardware driver problems, but it's always a good idea to ensure all of your PC device drivers are up-to-date to maximize PC performance. |
Step 5: Utilize Windows System Restore to 'Undo' Recent System Changes |
Windows System Restore allows you to 'go back in time' with your PC to help fix your Error 0x80029C4A problems. System Restore can return your PC's system files and programs back to a time when everything was working fine. This can potentially help you avoid hours of troubleshooting headaches associated with 0x80029C4A errors. Please Note: Using System Restore will not affect your documents, pictures, or other data. To use System Restore (Windows XP, Vista, 7, 8, and 10):
|
Step 6: Uninstall and Reinstall the Internet Download Manager Program Associated with Error 0x80029C4A |
If your 0x80029C4A error is related to a specific program, reinstalling Internet Download Manager-related software could be the answer. Instructions for Windows 7 and Windows Vista:
Instructions for Windows XP:
Instructions for Windows 8:
After you have successfully uninstalled your Error 0x80029C4A-associated program (eg. Internet Download Manager), reinstall the program according to the Tonec Inc. instructions. Tip: If you are positive that your 0x80029C4A error is related to a specific Tonec Inc. program, uninstalling and reinstalling your Error 0x80029C4A-related program will likely be the solution to your problem. |
Step 7: Run Windows System File Checker ('sfc /scannow') |
System File Checker is a handy tool included with Windows that allows you scan for and restore corruptions in Windows system files (including those related to Error 0x80029C4A). To run System File Checker (Windows XP, Vista, 7, 8, and 10):
|
Step 8: Install All Available Windows Updates |
Microsoft is constantly updating and improving Windows system files that could be associated with Error 0x80029C4A. Sometimes resolving your Runtime Errors problems may be as simple as updating Windows with the latest Service Pack or other patch that Microsoft releases on an ongoing basis. To check for Windows Updates (Windows XP, Vista, 7, 8, and 10):
|
Step 9: Perform a Clean Installation of Windows |
Caution: We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve Error 0x80029C4A problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately (download a highly-recommended backup solution) to protect yourself from permanent data loss. This step is your final option in trying to resolve your Error 0x80029C4A issue. Reinstalling Windows will erase everything from your hard drive, allowing you to start again with a fresh system. Furthermore, a clean install of Windows will also quickly clean out any and all 'junk' that has accumulated over the normal usage of your computer. Please Note: If 0x80029C4A errors still persist after a clean install of Windows, your Runtime Errors problem MUST be hardware related. If that is the case, then it is likely you will need to replace the associated hardware causing the 0x80029C4A error. |
