The conversion of the file APR to ADF will allow you to edit a file using other software than before. The conversion APR to ADF is particularly helpful in cases where you want to give certain features to the data in the APR file, and all the programs that support the APR format do not have the possibility to introduce the desired changes.
Just download one of the programs from the list and install it on your computer. After starting the program, select APR file that you want to convert. Then select the target format (in this case ADF) and follow the instructions. Save the converted ADF file in the selected location. From this moment you can open the ADF file with all the programs that you will find here.
