New Post: How to save directory structure with Write-Zip

waltermetcalf — Fri, 17 May 2013 23:37:51 GMT

Hi there,

I have written a script in Powershell 3.0 to backup selected files. But I've run into the same problem mentioned by a couple of other folks here, namely that the directory structure is not being saved. However in both the posts about this issue and the replies, no fix or workaround was mentioned.

It's really important that I find a solution to this problem. Otherwise, I'll have to complete re-design the script.

Does anyone know of a successful fix/workaround for this problem?

Thanks very much in advance.

PS. I am running on Windows 7 Professional 64-bit.

Closed Issue: Write-Zip -Append does not support -FlattenPaths [17794]

write-zip -append should have parity with archives created with plain write-zip. if not, it would be difficult to freshen files that have been flattened.

Closed Issue: write-zip bug: -flattenpaths has no effect when used with -append [27848]

oisin — Thu, 16 May 2013 11:57:49 GMT

Hi,

I'm trying to use the write-zip cmdlet and find the following odd behavior:

When I use the -append switch, files get added with path information, even when specifying the -FlattenPaths switch....

write-zip $files $outputFile -level 9 -FlattenPaths -append

Anybody come across this, or even better, found a work around?

Cheers!

Closed Issue: -EntryPath switch of Expand-Archive is non-functional [28313]

oisin — Thu, 16 May 2013 11:57:48 GMT

Steps to reproduce: Run the following script:
"hello world" | sc a.txt
Write-Zip -Path a.txt -OutputPath a.zip
Expand-Archive -path a.zip -OutputPath . -EntryPath a.txt

Expected Behaviour: a.txt file is extracted from a.zip archive into the current path.

Observed behaviour: Error message is displayed:
Expand-Archive : Object reference not set to an instance of an object.
At line:1 char:15
+ Expand-Archive <<<< -path a.zip -OutputPath . -EntryPath @("a.txt")
+ CategoryInfo : NotSpecified: (:) [Expand-Archive], NullReferenceException
+ FullyQualifiedErrorId : System.NullReferenceException,Pscx.Commands.IO.Compression.ExpandArchiveCommand

Additional information: The stack trace is like this:
at Pscx.Commands.IO.Compression.ExpandArchiveCommand.ProcessArchive(FileInfo fileInfo) in C:\Users\Keith\Pscx\Trunk\Src\Pscx\Commands\IO\Compression\ExpandArchiveCommand.cs:line 175

at System.Management.Automation.CommandProcessor.ProcessRecord()

Examination of the source code hints that EntryPath switch value is never used during the extraction process.

Workaround: Use -Index switch instead of -EntryPath switch

Closed Issue: Large Write-zip files cannot be extracted with 7zip 9.20 [32514]

oisin — Thu, 16 May 2013 11:57:45 GMT

The Write-Zip cmdlet appears to write zip files okay, but on large files (typical zip is 800MB or more), the files cannot be extracted when using later version of 7zip (e.g. 9.20, 9.22 etc), which gives an error "Unsupported compression method". I suspect this is because pscx is using quite an old version of the 7zip.dll files (v4.65), but simply replacing those DLLs in the pscx module folder has not resolved the issue (are the 7zip dlls embedded into the pscx dlls?).

Closed Issue: Expand-Archive fails with TAR file format [32847]

kevinsmotherman — Thu, 16 May 2013 11:57:45 GMT

The Expand-Archive cmdlet fails to extract the Tape Archive (TAR) file format.

Steps to reproduce:
1. Create TAR of image files (or any files of your choice):
Get-ChildItem *.img | Write-Tar -output archive.tar
2. Extract file:
Expand-Archive -Path archive.tar -Format Tar

Notes:
- No issues with Zip archive format using Expand-Archive cmdlet
- According to Expand-Archive documentation, the supported formats are:
SevenZip, Arj, BZip2, Cab, Chm, Compound, Cpio, Deb, GZip, Iso, Lzh, Lzma, Nsis, Rar, Rpm, Split, Tar, Wim, Z, Zip

New Post: Add Password functionality to Write-Zip cmdlet

deadlydog — Thu, 09 May 2013 20:09:55 GMT

It would be awesome if the Write-Zip cmdlet allowed you to also specify a password to password protect the zip archive with. I believe Write-Zip uses the same core libraries as 7zip, and 7zip is able to set passwords on zip archives. Of course, if this functionality is added to Write-Zip, the ability to specify a password to unzip a zip archive should also be added to Expand-Zip.
