Why do you need ‘Stellar Toolkit for File Repair’

Summary: Microsoft Office documents, ZIP folders, and other data files may get corrupt due to various reasons like large size, virus infection, and bad sectors on hard drive. This would mean complete loss of information, unless the corruption is resolved.

We also outline a specialty file repair toolkit that provides DIY utility for repairing corrupt Office documents (Word, PowerPoint, and Excel) and ZIP files. The file repair toolkit restores the document information & formatting to its original state.

Microsoft Word, Excel, PowerPoint, and Outlook are among the most widely used productivity software in the world. Zip file is another popular format used for archiving and distributing files via local transfer or over the Internet. While these file formats offer great convenience, they can get corrupt in certain scenarios (see below), leading to loss of valuable information.

Reasons behind File Corruption

Some of the common reasons for corruption of Microsoft Office files include:

  • Virus Infections
  • The sudden shutdown of the system while you’re working on the file
  • Bad sectors on the hard drive
  • Over-stuffing of data in a single file

Now let’s take a look at some of the reasons behind ZIP file corruption:

  • Improper compression of data within the ZIP files
  • Incomplete download of ZIP files from the Internet
  • Changes in browser settings
  • Abrupt system shutdown when the files are being compressed
  • Virus infections or bad sectors on the hard drive

Many of these reasons emerge from actions that may not be in your control, which means file corruption can affect anybody.

Let’s take a quick look at some of the manual techniques for repairing corrupted MS Office and ZIP files.

Here’s how to use this utility:

  1. First, launch the respective Office program through the Start menu
  2. Next, click on File -> Open or click on the Office button and then select Open. Don’t try to open the file through the ‘Recent’ section as it won’t launch the Open dialog box which is needed for this technique
  1. Browse to the location where the file is stored
  1. Select the file that you wish to repair by single-clicking on it and then click on the arrow next to the ‘Open’ button. This will open a drop-down which will contain the ‘Open and Repair’ option. Click on it

Repair corrupt ZIP files by using Windows command prompt

  2. The above step will enable built-in ZIP support from your computer
  3. Then restart your system and verify if the file is repaired.

For Windows 7/8/10

  1. Enter regedit in Run dialog box
  1. Expand HKEY_CLASSES_ROOT folder
  1. Click CLSID folder
  1. To disable the support for ZIP files, you need to delete this key:HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}
