If you are looking to Backup your CardExchange® Producer or CardExchange® Visitor settings and designs, then you can backup your Data folder which by default will store these files.

By default this is located here: C:\Users\Public\Documents\CardExchange\Data

In some cases, the data folder may not be in the default location, for example it may be on a network share so that it is already automatically backed up.
If this is the case you can check the current path being used for the data folder, to do this you will need to open the CardExchange.ini configuration file which is located in the installation directory.

For CardExchange® Gateway installations this will be:
C:\Program Files (x86)\CardExchange Solutions\CardExchange gateway\

For CardExchange® Producer, depending on the original version that was installed this could be either of the below locations:

C:\Program Files (x86)\CardExchange Solutions\CardExchange Producer\
C:\Program Files (x86)\ExchangeIT\CardExchange\

If you open the CardExchange.ini file in notepad you will see an entry for DataDirectory which will show you the current path.
