unzipping not working

[f15radar]

I have the following code:

    print("Zippath is "+zippath)
    print("unzippath is "+unzippath)
    print("url path is "+url.path)
    let fileManager1 = FileManager.default
    if fileManager1.fileExists(atPath: zippath) {
         print("Archive exists")
    }
    if fileManager1.isWritableFile(atPath: unzippath){
         print("dir writable")
     }
    do
        {
            try SSZipArchive.unzipFile(atPath: zippath, toDestination: unzippath, overwrite: true,password:"icp")
        }
        catch
        {
        print("error unzipping")
        }
    print("after unzip")

Here is my output:

Zippath is /var/mobile/Containers/Data/Application/DCE37610-39D1-4E94-8690-8178D50C571D/Documents/file.csvallpics.ggg
unzippath is /var/mobile/Containers/Data/Application/DCE37610-39D1-4E94-8690-8178D50C571D/Documents/unzip
url path is /var/mobile/Containers/Data/Application/DCE37610-39D1-4E94-8690-8178D50C571D/Documents
Archive exists
dir writable
error unzipping
after unzip

I have checked the zipped up file and it is valid, although I don't think there is a password. I also tried with a blank password and received the same error.

I followed the code down and saw a 107 error

What is a 107 error and why is this not working?

More information. The zip file is create with SSZipArchive and is greater then 6gb. I tried using a smaller file and it works. Can i not unzip files greater then 6gb?

It looks like the zip file which was created with ZipArchive is somehow corrupt. Now to try and figure out why.

So I am very perplexed, can someone help me? I have 4400 pictures in an iPhoneXR. When I run them thru the createzip using the documents directory, 1 file always gets messed up. When I say messed up, if I look at it using 7 zip, 1 file (not the same file everytime) is currupted. One time it was file 1566, last time it was 465. What could the problem be? I have been working on this for days now.
