By default, files are added to the catalog with their workstation file location set to the same path they were downloaded to. You can override this path using the /CATOVERRIDE=unix-path argument.
The value of the /CATOVERRIDE argument replaces the <catalogfolder> token when the file is added to the catalog. This enables you to import files to a Windows folder, but store them in the catalog as a Unix path. For this to work, the download target must start with the <catalogfolder> token, as this token is replaced by the value of the /CATOVERRIDE argument.
Example:
The following command downloads the file mfi01.test.data to c:\proj\dir\mfi01.test.data but then sets the catalog entry workstation file location to /user/user1/dir/mfi01.test.data. This happens because <catalogfolder> in the import target is replaced with c:\proj while downloading, but is then replaced with /user/user1/ when adding the entry to the catalog.
MFDAS IMPORT "<catalogfolder>\dir\*" FROM AUTO mfi01.test.data /CATLOC=c:\proj\catalog.dat /CATOVERRIDE=/user/user1/
