Sources of PD4 Problems


Common Problems Opening PD4 Files

DFSee Disappeared

Double-clicking your PD4 file prompts the message "%%os%% Can't Open PD4 File". Customarily, this means that DFSee is not installed on %%os%%. This will prevent you from double-clicking to open the PD4 file because the OS doesn’t know how to handle it.


Tip: Another PD4-related program can be selected to open the file by clicking "Show Apps" and finding the application.


DFSee is Out-of-Date

It is possible that your version of DFSee isn't able to open your DFSee Partition Table And Boot Sector Backup file due to incompatibility. Download the latest DFSee version from the Jan van Wijk website to ensure you have the correct one installed. Most of the time your DFSee Partition Table And Boot Sector Backup file was created by a newer DFSee than what you have installed.


Tip: Find clues on the correct software version by right-clicking your PD4 file and clicking "Properties".


Conclusion: The majority of PD4 file opening issues are due to not having the correct DFSee version installed.


More Causes of Problems Opening PD4s

You can still experience errors opening PD4 files even with the latest version of DFSee installed on your PC. Other PD4 opening errors can be created by other system problems inside of %%os%%. Additional factors include:

  • Invalid PD4 file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • The PD4 file description within the Windows Registry was removed
  • Incomplete or bad installation of a software application associated with the PD4 format
  • PD4 file corruption
  • The PD4 is infected with a virus
  • PD4-related hardware has device drivers that obsolete
  • Too many applications are open on your PC to load your DFSee Partition Table And Boot Sector Backup file successfully
