How do I retrieve a TP4 file from TPControl?

File retrieval from TPControl is not supported/implemented particularly because the TP4 file(s) stored on the device are altered specifically for use with TPControl, and will also have been renamed i.e. it is not the exact TP4 file originally created in AMX TPDesign4.

However, retrieving the altered TP4 file for Apple devices may be possible using a utility called iMazing (, formerly called DiskAid.

Now, if you are successful in retrieving the file, do not make and save any changes within TPDesign4 for that file - it will corrupt. Rather, you should be able to load the file in TPDesign4, but you will need to create a separate TP4 file and copy/paste pages and popups to the new file in order to re-create an editable version of the original TP4 file.

The following directions were applicable to Diskaid, but may still be applicable for the iMazing application:


Ensure that within 'DiskAid -> Preferences -> Storage' you have enabled the "Display all Apps even if they don't have their 'File Sharing' enabled", "Show root path for Apps", and "Show hidden files and folders" options. Then connect the device to browse the file storage under 'Apps'. If available, the file will be listed under 'Apps -> TPControl -> Documents -> Slot#' where # is the file slot number the TP4 file has been loaded into.
