A simple installation and registration, on opening a simple interface was presented.

Using a hex editor modified today's download zip file by modifying the names of the file it contains at the end of the compressed archive.
Attempted recovery was unsuccessful even though it claimed had recovered the files.

Using another copy of today's download modified the characters PK, that appear at the front of every zip file, to MZP typical of EXE files and DLL files.
Yet again it claimed a successful recovery but actually recovered nothing.

It was so unsuccessful that I was concerned that I was doing something wrong and so tried a number of times without success.

Been using compression programs for just short of 30 years and never needed to recover one.
If I was concerned about corruption of archives I would use RAR files where with slightly less than optimum compression they can be saved with a built-in recovery system.

I didn't have any broken ZIP.
So i made 4 ZIP from a series of photo's i used yesterday.
2 of them are protected with a password(gotd).

And these 4 zip's i have manipulated with a hexeditor. Not very much: something just altered the name of the original file. Another somewhere else in the zip altered 10 bytes to 0123456789.

The GOTD program has great difficulties with the password protected files: all the result-files has 0 bytes.
And the other unprotected files: the result were soso:
