“Actually I have an incomplete downloaded zip file in my computer and I just want to extract only that much of the file content which is present in it. Can anyone please tell me is there any software to extract partially downloaded zip files?”

So, you downloaded a ZIP file from Internet and when you tried to open it, you faced an error message “Invalid Zip file” or “Corrupt Zip file” and it asks you to download the file again. For zip files that are small in size, it is ok but what about files with very large size? Nobody will agree to download that file again.

  1. If all the contents of Zip file are important for you, then you need to download the files once again. There is no other option.
  2. If you want only some files that were downloaded during partial download, then you can make use of the Repair corrupted zip tool to unzip partially downloaded file.

The ZIP file format is commonly used for data compression and data archiving of large-sized files. With the help of ZIP files, all the related files can be kept together which makes transferring, downloading, e-mailing and storing of files easier. But like any other format with a well-defined structure, zip files are also highly sensitive to corruption issues. In case of even a slight corruption in the file structure, no standard zip tool will be able to extract its content. The reason is that the zip tools check the zip files for integrity i.e. Cycle Redundancy Check (CRC). If the CRC values of original file and the extracted ones, doesn’t match, then the standard tools will not extract them. Like in the case mentioned above, the zip file was not downloaded completely, that is why you were not able to unzip partially downloaded file. In that case Repair corrupted zip utility will help to extract partially downloaded zip file.
