Use the File System catalog source to extract metadata from files located on a Windows or a Linux machine into the catalog. You can use either the Local File System protocol to import metadata from the files located on a local machine or use the Remote File System protocol to import metadata from the files located on a remote Windows machine.
Note: To extract metadata from files located on a remote Linux machine, configure the SFTP File System catalog source in Metadata Command Center.
Metadata Command Center extracts files and folders from a Windows or a Linux file system.
You can extract workbooks, worksheets, and columns from Microsoft Excel files.
Supported file types
The following table lists the structures associated with the file types that you can extract metadata from:

Note: File System catalog sources can only extract input files encoded in UTF-8.
You can extract metadata from TSV and TXT file types.
You can extract metadata from XML and XSD file formats as XML file objects. Metadata Command Center extracts only elements and attributes from XML and XSD files. If the size of the XML file exceeds 100 KB, Metadata Command Center extracts metadata from the initial 100 KB of the file. However, for XSD file types, Metadata Command Center extracts complete metadata.
