Creating Zip files using PowerShell - powershell

Question

I have these below files at a location C:\Desktop\Mobile.
Apple_iphone6.dat
Apple_iphone7.dat
Samsung_edge7.dat
Samsung_galaxy.dat
Sony_experia.dat
Sony_M2.dat
I need to create a script that writes the similar files into a single zip. So files Apple_iphone6.dat and Apple_iphone7.dat must be into single zip.
So the final zip files created would be:
Apple_Files_Timestamp.zip
Samsung_Files_Timestamp.zip
Sony_Files_Timestamp.zip
I tried this
Get-ChildItem C:\Desktop\Mobile -Recurse -File -Include *.dat | Where-Object { $_.LastWriteTime -lt $date } | Compress-Archive -DestinationPath C:\Desktop\Mobile
But it gives me error 'Compress-Archive' is not recognized as the name of a cmdlet.
How can I get this code work?

Answer 1

You have two problems, I will try to summarize both of them.
1. Compress files
In order to use Compress-Archive command you need to have PowerShell 5 as already commented by #LotPings. You can:
run your script on Windows 10 machine, or Server 2016 which are coming with v5
download and install PoSh 5, see details on MSDN
If you cannot do either of those, you can
install some module from PowerShell gallery that provides similar functionality via 7-zip tool. Search resultes are here. Download and check those modules before use!
use .NET 4.5 class, check answer here on Stack Overflow
2. Group files
Once you group files, you can easily pipe them to compressing command, similar as you already tried. Proper grouping would be achieved with something like this:
$Files = Get-ChildItem 'C:\Desktop\Mobile'
$Groups = $Files | ForEach-Object {($_.Name).split('_')[0]} | Select-Object -Unique
foreach ($Group in $Groups) {
$Files | where Name -Match "^$Group" | Compress-Archive "C:\Desktop\Mobile\$Group.7z"
}

Answer 2

Pre Powershell v5 you can use this. No additional downloads needed.
$FullName = "Path\FileName"
$Name = CompressedFileName
$ZipFile = "Path\ZipFileName"
$Zip = [System.IO.Compression.ZipFile]::Open($ZipFile,'Update')
[System.IO.Compression.ZipFileExtensions]::CreateEntryFromFile($Zip,$FullName,$Name,"optimal")
$Zip.Dispose()

Answer 3

With Powershell 2.0 you can't use Compress-Archive, you need download the original terminal executables to zip and unzip files from here.
You can use:
zip <path> <zip_name> -i <pattern_files>
In your example:
zip "C:\Desktop\Mobile" Apple_Files_Timestamp.zip -i Apple*.dat
zip "C:\Desktop\Mobile" Samsung_Files_Timestamp.zip -i Samsung*.dat
zip "C:\Desktop\Mobile" Sony_Files_Timestamp.zip -i Sony*.dat
If you need use adittional zip options, visit zip manual.

Answer 4

The following script does the grouping,
the zipping command depends on your chosen zipper.
$TimeStamp = Get-Date -Format "yyyyMMddhhmmss"
Get-ChildItem *.dat|
Group-Object {($_.Name).split('_')[0]}|
ForEach-Object {
$Make = $_.Name
Foreach($File in $_.Group){
"{0,20} --> {1}_Files_{2}.zip" -f $File.Name,$Make,$TimeStamp
}
}
Sample output:
> .\SO_44030884.ps1
Samsung_edge7.dat --> Samsung_Files_20170517081753.zip
Samsung_galaxy.dat --> Samsung_Files_20170517081753.zip
Apple_iphone6.dat --> Apple_Files_20170517081753.zip
Apple_iphone7.dat --> Apple_Files_20170517081753.zip
Sony_M2.dat --> Sony_Files_20170517081753.zip
Sony_experia.dat --> Sony_Files_20170517081753.zip
