Cannot Open Zip File? Fixed It with Tested Methods Here!

One of the most commonly used formats for the compression of files is the Zip format, represented as the .zip file extension. It is a single file that contains a set of compressed files. When files are compressed into Zip format, their sizes get considerably reduced which makes for easier transfer and use of less space. However, the files have to be unzipped before you can view them. It becomes an issue if you cannot open zip file after you convert a folder to Zip.

This article is available to give you all the information you need on why you cannot open your Zip file. Some great software will be suggested for you to use in unzipping your Zip files. Finally, you will learn about Repairit File Repair and how you can use it to open your Zip files that have been corrupted by one factor or the other.

Part 1: Why Can't I Open the Zip File?

In this part, you will find out the major reasons why you cannot open your Zip file. The reasons for compressed or Zip files not opening include the following:

Incomplete Downloads

Zip files may refuse to open if they are not properly downloaded. Also, incomplete downloads occur when files get stuck due to issues like bad internet connection, inconsistency in network connection, all of which can cause transfer errors, affect your Zip files, and make them unable to open.

Improper Compression

File compression can get halted due to unforeseen circumstances such as abrupt power failure or low battery which can cause a system shutdown. This could corrupt the file undergoing the compression process. Consequently, the Zip file may become damaged and refuse to open.

File Corruption

This is a major reason why your Zip files are proving difficult to open. A particular corruption that stops the opening of Zip files is the header corruption. A Zip file has a feature called "header" which is responsible for keeping information such as the file name, the date you created it, file size, and so on. The information in a header is essential in opening or accessing the contents contained within the file. This only goes to say that if the header is corrupt, there will be the challenge of the Zip file not opening.

Changed File Extension

A Zip file can be seriously damaged if its extension is changed to another format that is not supported on Windows. A Zip file that is severely damaged may not open when you are trying to extract its data.

Virus Infections

If your Zip file is stored in an external storage device and the device gets damaged from exposure to such hazards as magnetic fields, dangerously high temperature, or even mechanical shock, it can affect the contents of the drive, including the Zip file in it. This can lead to corruption and your inability to open the Zip, even if the drive eventually gets repaired. Also, another reason could be if you forget the password to your encrypted archive file. However, this is only applicable if you originally assigned a password to your Zip file.

Other Reasons

The incorrect file extension is another issue that may trigger the 0xc10100bf error. This situation mostly occurs when you have renamed a file without properly converting it through a dedicated video conversion software or tool.

Part 5: Common Errors when Opening Zip File

There are several errors associated with the opening of Zip files, convenient as the format may be. Some of the common errors you may encounter when opening Zip files are enumerated below:

Invalid Archive: This is inarguably one of the most common errors you can be sure to face when opening Zip files. Your Zip file can be rendered invalid if it gets corrupt from an interruption during its download, transfer, or copy. It can also be from internet interruption or bad network during the download of the file.

Corrupt/Damaged Archive: This error may be caused by over usage of the zip file, infection from a virus, sudden power loss during Zip file extraction, or an increase in the bad sections of the location where the Zip file is located. These factors can lead to loss of important data in the Zip file, corruption, and blockage of access for file contents. It can ultimately prevent you from opening your Zip file.

Unknown Method of Compression: You can get this error message when you are trying to extract a Zip file:

This file was compressed using an unknown compressing method

This simply means that the compressor version used to compress the Zip file is different from the one you are trying to use to unzip the archive file.

Invalid/Corrupted Zipped Folder: This is also caused by errors from interrupted downloads due to power interruption, or virus infection. In this case, although the Zip file is corrupt, you may still be able to open it but some of its original data can go missing. Attempting to open such a damaged Zip file will only prompt an error message like this to appear:

CRC Error: This error occurs from damage to data within your Zip file. CRC is an acronym for Cyclic Redundancy Check. It is a value that is calculated by the compressor and saved in the newly created Zip file. When you open the file, the compressor will calculate the CRC value once again and if it doesn't tally with the one initially created and saved, the CRC error is sure to appear on your screen. This is a way of telling you there is a problem with the data in your Zip file.

Part 6: Which Zip File Can be Opened on Windows?

There are many archive file formats out there such as Rar, TZ, GZ, Zip, 7Zip, BZip, and so on. It can be overwhelming trying to choose which format to use, especially if you are not sure the file can be opened on your Windows. Therefore, this part will show you the three major Zip files that can be opened on Windows as discussed below:

Zip: This archive format is ideal for large files to be transferred because you can compress more than one file into it, thereby reducing the time and resource wastage that comes with transferring large files. It also helps in keeping similar files in a single location. Zip is regarded as the most common compression format used on Windows for the sharing and emailing of files. Your Windows can internally handle Zip files without you having to seek the help of external software or an extra tool.

ZipX: This type of Zip file is more advanced than the normal Zip file format. ZipX files contain several files that are compressed into the extended version of Zip format and in smaller sizes than the previous Zip formats. This is where the advanced function comes into play. ZipX was developed by WinZip (WinZip 12.1) and it can be opened on Windows.

7Z: This file compressed format (also known as 7-Zip) was created by Igor Pavlov with the use of various compression utilities. 7Z file has a high ratio of compression and strong AES-256 encryption. It enables you to transfer Zip files easily while saving storage space for your system. It is interesting to note that the 7Z file format was introduced by Windows itself so you are assured it can be opened on your Windows.
