| 8 | A record is read from the input source file located in the import folder of the Zope instance. The data format is validated against the import data layout selected. If the record can be imported, it is **appended** to the file [layout]_imported.csv (in the same folder), otherwise it is **inserted** into the file [layout]_pending.csv, if no record with exactly the same data already exists. Technically speaking, the md5-digests of the new record is being compared with the existing records.
