Azure Pipelines - Is there a way to view the folder structure?

You can use CMD task to call tree command in Microsoft-Hosted windows agent to get the folder structure.

My script:

echo "Structure of work folder of this pipeline:"
tree $(Agent.WorkFolder)\1 /f

echo "Build.ArtifactStagingDirectory:" 

echo "$(Build.ArtifactStagingDirectory)"

echo "Build.BinariesDirectory:" 

echo "$(Build.BinariesDirectory)"

echo "Build.SourcesDirectory:"

echo "$(Build.SourcesDirectory)"

The result:

$(Agent.WorkFolder) represents the working folder for current agent, $(Agent.WorkFolder)\1 represents the working folder for current pipeline.(Normally the first pipeline will be put in $(Agent.WorkFolder)\1, and the second $(Agent.WorkFolder)\2...)

So it's obvious that for one pipeline run, it has four folders by default: a(artifact folder), b(binaries folder), s(source folder) and TestResults(Test results folder). The s folder is where the source code files are downloaded. For build pipeline: $(Build.SourcesDirectory),$(Build.Repository.LocalPath) and $(System.DefaultWorkingDirectory) represent the same folder. More details see predefined variables.

Another option is to add this to a YAML pipeline:

-powershell: Get-ChildItem -Path 'Insert root path' -recurse

It will look something like:

Get-ChildItem -Path C:\Test\*.txt -Recurse -Force

Directory: C:\Test\Logs\Adirectory

Here is documentation on the Get-ChildItem command if you need more information

The documentation gives you examples of the folder structure. If that's not enough, add a PowerShell step that runs gci -rec -directory | select-object fullname or similar.

Note that your full path may look different based on your environment.

For example: your Build.StagingDirectory path could be c:\agent_work\1\a OR
/home/vsts/work/1/a/

This is based on Agent.BuildDirectory or Pipeline.Workspace variable.(c:\agent_work\1 or /home/vsts/work/1 or /a/1 or something similar)

It looks more like this(work directory of an Agent):
