如何使用Compress-Archive压缩/存档隐藏文件？

Question

使用Compress-Archive压缩文件夹时,它会跳过所有隐藏文件.

"文档"页面告诉我们此cmdlet 在后台使用Microsoft .NET Framework API System.IO.Compression.ZipArchive.

有没有办法强迫它存档隐藏文件？我无法在任何地方找到此问题.我试过-Force它,没有帮助.

我目前的解决方法是Set-FileAttribute在压缩之前使用删除隐藏属性.

Answer 1

我替换Compress-Archive为\[System.IO.Compression.ZipFile]::CreateFromDirectory(sourceDirectoryName, destinationArchiveFileName)并发现（至少在 macOS 上）ZIP 文件包含一个以 开头的目录.（这是在 macOS 上隐藏目录/文件的一种方法）。这是使用 PowerShell 7.2。

This looks like a bug/oversight in the Compress-Archive cmdlet. Since the cmdlet provides no "include hidden files" parameter but does accept a collection of source files via the -Path or -LiteralPath parameters, I would expect either this...

Compress-Archive -Path (
    Get-ChildItem -Path '...' -Force `
        | Select-Object -ExpandProperty 'FullName' `
) -DestinationPath '...'

...or this...

Get-ChildItem -Path '...' -Force | Compress-Archive -DestinationPath '...'

...to work as a way of passing hidden files to the cmdlet; the key being specifying the -Force parameter for Get-ChildItem. Both of those invocations, however, throw these errors...

Get-Item : Could not find item ....

Exception setting "LastWriteTime": "Cannot convert null to type "System.DateTimeOffset"."

...for the first hidden file in the input list. (Note that invoking the first snippet without Select-Object -ExpandProperty 'FullName' instead throws Compress-Archive : The path '...' either does not exist or is not a valid file system path..)

On my system, the referenced lines 812-814 of Microsoft.PowerShell.Archive.psm1 are...

# Updating  the File Creation time so that the same timestamp would be retained after expanding the compressed file. 
# At this point we are sure that Get-ChildItem would succeed.
$currentArchiveEntry.LastWriteTime = (Get-Item -LiteralPath $currentFilePath).LastWriteTime

So, even if we pass -Force to Get-ChildItem to get the paths of hidden file objects to pass to Compress-Archive, internally the cmdlet is fetching those file objects again using Get-Item...but it's not passing -Force, which of course will fail (despite what the comment on the previous line claims). Thus, I don't think there's any way to get Compress-Archive to work with hidden files without either you or Microsoft editing that script.
