What is the D1 file?
The D1 file extension can be associated with several types of files. Most often, however, a file with such an extension is associated with the Progress Database format. D1 files are supported by Windows operating systems. The D1 file is one of the Database Files files, just like 403 of the other files found in our file information database.

How to open a .D1 file?
If you have problems opening the file D1, then in most cases the problem is only the lack of the proper application installed. Select one of the programs from the list and install it on your device. The operating system should automatically associate the D1 file format with the installed program. If not, right click on your D1 file and select from the menu "Open with" . Then select the installed program and confirm the operation. Now all D1 files should automatically open with the selected program.
