ADO Agent folder structure

https://stackoverflow.com/questions/63117797/azure-pipelines-is-there-a-way-to-view-the-folder-structure

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)"

$(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.
