Question:
I’m trying to add a file to a zip file using powershell
I can create the zip file but can’t work out how to add my file to it
I’m using
|
1 2 3 4 5 6 7 |
$zipfilename = 'c:\cwRsync\backup.zip' $file = 'c:\cwRsync\backup.log' set-content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18)) (dir $zipfilename).IsReadOnly = $false $zipfile = (New-Object -ComObject shell.application).NameSpace($zipfilename) $zipfile.MoveHere($file.FullName) |
This create the zip file but doesn’t add the new file
I tried the following code I found on stackoverflow which works
|
1 2 3 4 5 6 7 8 |
$zipfilename = "a.zip" set-content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18)) $app = new-object -com shell.application $zip = ( get-item a.zip ).fullname $folder = $app.namespace( $zip ) $item = new-item file.txt -itemtype file -value "Mooo" -force $folder.copyhere( $item.fullname ) |
but that add a file created by powershell whereas I want to add an existing file
Any help would be much appreciated
Answer:
The CopyHere function just takes a string that is the path to your file. For example:
|
1 2 |
$folder.copyhere( "c:\PathToYourFile\YourFile" ) |
Edit: The Powershell Pack mentioned in the tip below is no longer available. I leave it here in case someone can find it archived somewhere and can update this post with a link.
Tip:
The Powershell Pack Module has some useful tools, one of which is a zip utility, which will reduce your code to 1 line:
|
1 2 |
Copy-ToZip "c:\PathToYourFile\YourFile" -ZipFile a.zip |
