The reason behind this is that the Binary mode supports the transfer of images, and is the most preferred mode for FTP transfers. Whereas the ASCII mode is used only for the text transfer as it converts the data into 8-bit ASCII codes.

If you are a regular WinZip user, then you must be acquainted with the kind of error messages that appear while you try to extract the zip archive. Sometimes, an error message appears due to file version mismatch, which leads the way to .zip file corruption.

A zip file header is the location in the Zip file where all the information about the file is stored. The information can be about the file creation date, size of the file, etc. But, when the header gets corrupted, it can cause the whole Zip file to become corrupt. As a result of corruption, the data stored in the Zip file becomes inaccessible. An ideal way to overcome such situations is to restore the data from a recent and valid backup file. But, in case the backup is not available, or also gets corrupted, then a powerful zip repair software will enable you to retrieve your data from the corrupted Zip file.

For instance – Sometimes, while you try to extract the zip archive, the process fails and you encounter the below mentioned error message:

“header corrupt”

You may also encounter this error message due to corruption in self-extractors along with Zip files, provided the error message occurs frequently.
