Notes about the DPLM file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The DPLM file type is primarily associated with 'DPLM - Digital Path Lines Memorizer' by DELPHI 4U. This Delphi tool was made to draw lines. It saves line coordinates to take less disk space than a picture. (Only in Slovenian language.)
