Processed Data
|
Description
|
Replace existing files
|
Overwrites the existing files in the processed data area with the new processed files.
Deleted files in the raw data area are also deleted in the
processed data area.
|
Rename existing files
|
Adds an underscore and a sequential number to the names of the old files
in the processed data area, and saves the new processed
files under the original name in the processed data area.
The file with the lowest sequential number is therefore
always the latest version of a processed file. You cannot
combine this setting with the React to deleted
files setting.
|
Save under a new, unambiguous filename
|
Saves the new processed files in the processed data area under the original name with an underscore and a sequential number.
The file with the highest sequential number is therefore always the latest version of a processed file. You cannot combine
this setting with the
React to deleted files setting.
|
Flag processing as error
|
Saves the new processed files in the processed data area under the original name, and assigns the name
Error, extended by an underscore and a sequential number, to the original files in the process data area. You cannot combine this
setting with the
Process changed files setting.
