In addition to the data files, there is also an OK file for each different file extension in each subfolder. This is a zero length file whose name is of the form:
YYYYMMDDHHMMSS_ok<Syncsort Capacity Management Target Number>.<extension>
This is a zero length file created by Acquire as a signal to the collection process that the data is ready to be collected. The file is not actually copied; rather, a file of that name is created in the relevant subfolder(s) of the tgtnnnnnnnn folder when the Acquire files gave been successfully written. If the OK file for a given file extension is not present, Control Center will not process that data into the Capacity Database.
