Answer 1

foreach ($filename in Get-Content .\ListOfFilesToZip.txt)
{
Compress-Archive -Update $filename .\ZipFile.zip
}

Answer 2

The following function can compresses a whole folder structure into a single zip file and will keep the structure within the zip (even works with PowerShell <5).
function createZipFile($outputFileName, $sourceDirectory){
Add-Type -AssemblyName System.IO.Compression.FileSystem
$compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal
[System.IO.Compression.ZipFile]::CreateFromDirectory($sourceDirectory, $outputFileName, $compressionLevel, $false)
}
Call it like that:
createZipFile "c:\temp\output.zip" "c:\folder\to\compress"

Answer 3

Not sure if there's any better way of doing this, but you can create a temp folder, copy the files to be archived along with desired folder structure over there and then just zip up the whole thing.
Take a look here (not my code, but seems to do exactly that) for a sample

Answer 4

Edit If question is about getting filename from the path
The most efficient way would be with a regex, but they can be rather complicated if you are not used to working with them.
A simpler way would be to simply split each string and select the last part where the file name is:
$string = "c:\asd\qwe\zxc\dog.txt"
#Split the string on each \
$string.Split("\")
#This will output a list like this
c:
asd
qwe
zxc
dog.txt
Now we want to simply select the last entry in this list as the filename is always last in a path. So we use Select Object for that.
$string.Split("\") | Select-Object -Last 1
This will return:
dog.txt
You can run this through a foreach on your list to get it for each item.

function DirNewTemp {
$tmpdir = (New-TemporaryFile).FullName
Remove-Item -Force -Path $tmpdir -ErrorAction 'SilentlyContinue'
New-Item -Type Directory $tmpdir | out-null
return $tmpdir
}
function ZipFiles {
param(
[string]$Zip,
[string[]]$FileList
)
write-host ""
write-host "====================================="
write-host "ZipFile $Zip"
write-host "====================================="
$pwd = (Get-Location).Path
$tmpdir = DirNewTemp
try {
$count = $FileList.Count
foreach ($file in $FileList) {
$pwd_escaped = [Regex]::Escape($pwd)
$save_file = $file -replace "^${pwd_escaped}\\", "${tmpdir}\"
$save_path = Split-Path $save_file -Parent
New-Item -Force -Path $save_path -ItemType Directory | out-null
Copy-Item -Force $file $save_file
}
set-location $tmpdir
$dest = "$pwd\$Zip";
write-host "Creating Zip: $dest"
Compress-Archive -Force -Path * -DestinationPath $dest
}
finally {
write-host "cleanup"
set-location $pwd
remove-item -Force -Recurse -Path $tmpdir -ErrorAction 'SilentlyContinue'
}
}
