Reading and uploading zip files from Powershell - powershell

Question

My below code successfully read a folder and uploades the subfolder one by one as a zip file in SharePoint. But if any of my file is of Zip extension, it gives me an error. I would like to know how can I fix my existing code below to handle the zip files as well so that it loads both the zip folder and non-zip files and folders in the SharePoint. I tried multiple tings like removing .zip extension in the Create-Archive and file but it does not work.

Answer 1

If it's only failing on files that are .zip prior to the CREATE-ARCHIVE function being run.
What happens if CREATE-ARCHIVE ignores .zip files?
if (-not($_.name -like "*.zip")){
CREATE-ARCHIVE....
} else {
COPY-ITEM $workingDir\temp\$($_.name)
}
Seems like archiving an archive is unnecessary work, and potentially the source of an issue.
