Fix Repair corrupted zip file and error messages like Unsupported Compression Method
Dear Reader, sometimes you may have encountered a situation where you came to know that the Zip file you created or downloaded, which indeed carries data that is much needed to you but all of a sudden, to your biggest surprise, you get an error message from Windows showing:
"Windows cannot open the archive C:Abc.zip is invalid "
This is where, it becomes more tragic, especially if youve created that Zip file using obsolete compression app.. & it contains a lot of your personal and/or professional data�
{ You might have encountered that Windows explorer or any other compression software such as WinZip fails to open that archive but 7Zip or WinRAR opens the archive and displays the file contents as a regular zip file but both are unable to extract them.. }
