Iterate Workspaces (ModelBuilder)—ArcMap

Summary

Iterates over workspaces in a folder.

This tool is intended for use in ModelBuilder and not in Python scripting.
Iterate workspace can be limited to iterate over workspace types such as Access, Coverage, File Geodatabase, Folder, or SDE.
The tool has two outputs: Output Workspace and Name which could be used as in-line variables %Name% in other tools.
If an Iterator is added to a model, all tools in the model iterate for each value in the iterator. If you do not want to run each tool in the model for each iterated value, create a sub-model/model within a model/nested model that contains only the iterator and add it as a model tool into the main model.

arcpy.mb.IterateWorkspaces(in_folder, {wildcard}, {workspace_type}, {recursive})

Parameter	Explanation	Data Type
in_folder	Folder which stores the workspace to iterate.	Folder
wildcard (Optional)	Combination of * and characters that help to limit the results. The asterisk is the same as saying ALL. If no wildcard is specified, all inputs will be returned. For example, it can be used to restrict Iteration over input names starting with a certain character or word (e.g., A* or Ari* or Land*,and so on).	String
workspace_type (Optional)	Choose the Workspace Type, such as Access, Coverage, File Geodatabase, Folder, or SDE. ACCESS —Only Access database will be the output. COVERAGE —Only Coverage will be the output. FILEGDB —Only File Geodatabase will be the output. FOLDER —Only Folder will be the output. SDE —Only SDE database will be the output.	String
recursive (Optional)	Determines if subfolders in the main folder will be iterated through recursively. Checked—Will iterate through all subfolders. Unchecked—Set as Default. Will not iterate through all subfolders.	Boolean

This tool does not use any geoprocessing environments.
