Read & Writing File Operations
The Read & Write File operations provide a means to read cards, saving the read track
data to a file and using the same file to write the same information to a new set of cards.
The cards read are a data source for the opened file. One card or a sequence of cards can
be read. Each card read creates a separate record within the file. The records are added
to the file in the sequence they are read. The number of records added to the file equals
the number of successfully read cards. When writing from the file, each card is written with
the data from one of the records starting from the first data record and written in the same
order as cards were read.
The Reading & Writing File Operation files are kept in the default file folder “To From Files”,
which is a sub-folder in the “IdtMsrwWorkShop” in the Program Files folder. The To From
Files can be moved and accessed from other folders. The files have a file extension that
matches the “Card Type” used to create the original file. Card Type is defined in the upper
right hand menu box on the Workshop main window. The card type cannot be mixed; the
card type must be consistent within a file.
Read To File
Selecting this function generates a Windows Explorer window to open an existing data file
or create a new data file. If an existing file is selected, the previous data is maintained and
the new card data is appended as cards are swiped. After a file selection is made, a
second window opens to prompt the swipe of a card. The reading result is shown in the
Message box for each swipe. If there is a read error, the card data is not saved; swipe the
card again to enter the card data into the file.
Write From File
This functions Writes data from a named file to a card. The card data is in a file records
created by the “Read To File” operation as described above. The Write To File function
prompts the user to open an existing data file. When a file is selected, the user is prompted
to swipe a card (or sequence of cards); each card is written with the next data record from
the file. The Message box shows the writing result for each card. If there is a write error,
the current data record is used until the record is successfully written to a card. Cards are
written until the last record is used. When the last data record is written, a prompt informs
the user the writing process is finished.
