Can files on a PakBus data logger be hidden?
The FileManage() instruction can be used to hide files on a data logger. The following are some important reminders:
- Hidden files will not be displayed and therefore are not accessible via File Control, FTP, HTTP, etc.
- Hidden CR and DLD program files and those specified by the Include instruction can be used by the data logger.
- Hidden files can be accessed under program control using the FileOpen(), FileRead(), and FileWrite() instructions.
- Hidden files can be further protected by encrypting them with the CRBasic Editor or the FileEncrypt() instruction.
