Hi,

I am new to PowerShell and the Azstorage commands.

I am trying to get a list of all files and folders in an Azure Storage fileshare but having difficulty getting my script to work. I have tried various combinations but it is not finding the subfolders or the files.

I have a test fileshare which has 2 folders at the root level Dir1 and Dir 2 and 1 subfolder and 1 file

Dir1

Subdir1

TestFile.PDF

Dir2

The script i am trying at the moment is below. I am initially trying to set the 1st folder DIr1 as the input to the function with the idea that it then pulls in the subfolder, etc but it does not work as it is not bringing back the subfolder under Dir1 and I am not sure why, any help would be appreciated.

Variables

$SasToken = "xxxxxxxxxxxxxx"

$fileShareName ="yyyyyyyyyy"

Create a storage context

$StorageContext = New-AzStorageContext -StorageAccountName "zzzzzzzzzz" -SasToken $SasToken

$directories=Get-AzStorageFile -ShareName $fileshareName -Context $storageContext | Where-Object {$_.GetType().Name -eq "AzureStorageFileDirectory"}

foreach ($item in $directories) {

Write-Output "Folder is : $($item.Name)"

$directoryPath = $item.Name

Get-AzFileShareContent -shareName $fileShareName -directoryPath $directoryPath

}

Function to recursively list files and folders

function Get-AzFileShareContent {

param (

    [string]$fileshareName,

    [string]$directoryPath #= ""

)

# List files and directories in the current directory

$files = Get-AzStorageFile -Context $storageContext -ShareName $fileshareName -Path $directoryPath | Get-AzStorageFile

foreach ($file in $files) {

    if ($file.GetType().Name -eq "AzureStorageFileDirectory") {

        # Output the folder path

        Write-Output "Folder: $($directoryPath)\$($file.Name)"

        # Recursively call the function for subdirectories

        Get-AzFileShareContent -shareName $fileshareName -directoryPath "$directoryPath\$($file.Name)"

    } else {

        # Output the file path

        Write-Output "File: $($directoryPath)\$($file.Name)"

    }

}

}

Hi NJ,

you are very close! The main issue is with this line in your recursive function:

$files = Get-AzStorageFile -Context $storageContext -ShareName $fileshareName -Path $directoryPath | Get-AzStorageFile

Remove the Pipe from the recursive function. The second Get-AzStorageFile is unnecessary and causes the function to fail in retrieving subfolders and files.

Apart from that few basic changes you can try

1.Start from the root path ("") to ensure all folders and files are included.

$directories = Get-AzStorageFile -ShareName $fileshareName -Context $storageContext | Where-Object {$_.GetType().Name -eq "AzureStorageFileDirectory"}

doesn’t specify a -Path, so it defaults to the root and only lists the root-level directories. It doesn’t trigger recursion into subdirectories unless explicitly handled.

2. Function call placement

The recursive function is defined after it’s called in the loop:

foreach ($item in $directories) {
    ...
    Get-AzFileShareContent -shareName $fileShareName -directoryPath $directoryPath
}

define the function before calling to avoid scope issues

Hi Muksan,

Thanks for the response. Unfortunately I still don't get the output I expect. The first time through, it picks up Dir1 which is fine, then when it gets to

$files = Get-AzStorageFile -Context $storageContext -ShareName $fileShareName -Path $directoryPath

for the 2nd time, it still picks Dir1 and I was expecting it to pick Subdir1, also, for some reason it also loses the fileShareName which it had up to the point of entering the function for the 2nd time and throws an error

Get-AzStorageFile : Cannot validate argument on parameter 'ShareName'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

Here is my updated script

$SasToken = "xxxxxxxxxxxxxx"

$StorageContext = New-AzStorageContext -StorageAccountName "zzzzzzzzzz" -SasToken $SasToken

Function to recursively list files and folders

function Get-AzFileShareContent {

param (

    [string]$fileShareName,

    [string]$directoryPath #= ""

)

# List files and directories in the current directory

$files = Get-AzStorageFile -Context $storageContext -ShareName $fileShareName -Path $directoryPath ##| Get-AzStorageFile

foreach ($file in $files) {

    if ($file.GetType().Name -eq "AzureStorageFileDirectory") {

        # Output the folder path

        Write-Output "Folder: $($directoryPath)\$($file.Name)"

        # Recursively call the function for subdirectories

        Get-AzFileShareContent -shareName $fileShareName -directoryPath "$directoryPath\$($file.Name)"

    } else {

        # Output the file path

        Write-Output "File: $($directoryPath)\$($file.Name)"

    }

}

}

$fileShareName ="yyyyyyyyy"

$directories=Get-AzStorageFile -ShareName $fileShareName -Context $storageContext -Path "" | Where-Object {$_.GetType().Name -eq "AzureStorageFileDirectory"}

foreach ($item in $directories) {

Write-Output "Folder is : $($item.Name)"

$directoryPath = $item.Name

Get-AzFileShareContent -fileshareName $fileShareName -directoryPath $directoryPath

}

Hi,

I seemed of fixed the issue with the filesharename, by adding the variable within the function. Not sure why it needs it there but script now works fine. I did add back in the pipe Get-AzStorageFile as it errored without after making the other changes.

output:

Folder is : Dir1

Folder: Dir1\Subdir1

File: Dir1\Subdir\Testfile.pdf

Folder is : Dir2

Thanks...
