ADF file extension is a raster data file format used by various software created by ESRI, such as ArcView, ArcInfo, and ArcGIS. Single ADF contains vector, spatial, and geographical attributes data.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the APR file after converting to ADF may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from APR to ADF to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting APR to ADF does not meet your expectations, you can simply try to find on the Internet a different version of your file in APR format, properly converted to a ADF file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file APR the desired result was not achieved, you can try to change the format of APR file to other than ADF. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your APR file converted by someone else, and the attempt to convert it to ADF on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the APR file in its original format (without conversion to ADF file). Such a solution will be difficult to implement, but it certainly will give the best result.
