File name in zip file corrupted

I have a zip file which has a corupted file name - ie. the zip file contains only one file, but the file name is a NULL - winzip, winrar etc. can recognize that there is a file but cannot unzip it as there is no "file name" in the zip archive for the file. Some repair utilities seem to "find" the file but cannot fix the file name in the zip archive - I am a little loath to keep purchasing zip repair utilities that ultimately fail to fix the file. I really need to find a way to fix this file. Any suggestions or info about repair utilties that can deal with fixing the filename header in a zip file would be greatly appreciated.

 

How exactly are you attempting opening the .zip file? (I mean through through Explorer?)

Try using 7-zip
Or
Recovery Toolbox for Zip - https://repairzip.recoverytoolbox.com/

It is possible that the .zip file for *whatever* reason is not fully compatible with the Windows built-in zipfld.dll.
