How to create a list of files Zipped

I have a couple of huge zip files I need to report on. This was an extraction from a legacy db. There are multiple sub directories and the names are longer than 256 characters so winzip truncated the names. (don't ask why ). I need to report on which names were truncated and the directories. I am using windows 7.

The report should have the full path and file name of truncated files and a second report of all file names.

I was thinking of finding the truncated names either by length or a file that does not have an extension.

I was able to get this much done in PowerShell ISE:
cd "C:\BI"
$name="test";dir -r|%{File name:{0} - Extension:{1} };$name
$len=0;dir -r|%{if ($_.FullName.Length -gt $len) {$len=$_.FullName.Length}};$len


$folders = "C:\BI"
foreach($folder in $folders){

foreach($file in (dir -Recurse $folder)){

$file
$length += $file.length

}
Write-Host ($length)
$length = 0
}

Results:
Directory: C:\BI

but I want the length of directory and filename and list only if it is over 256...... arg

Thanks for any help!
