The MDPLUS Franchise Data Import program will automatically extend the file sizes in case a file has no space available to store the MDPLUS data. This will slow down the import process and it is therefore recommended to set the sizes of the files big enough before starting the import.
In the Tools menu is an option available that shows the available space for the files that are used by the MDPLUS Franchise Data Import program. The Available space screen will be shown when the option Show file information is selected. In case the available records are shown in red is it recommended to extend that file.
