How to open ARFF file?
The main problem with Weka Attribute-relation Format is that the ARFF file is incorrectly associated with programs. Thus, when you open ARFF, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the ARFF file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Weka
In this case, you should first verify that the Weka application is installed on the computer. The easiest method is to use the system search engine by entering the program name Weka in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support ARFF files.
Programs to open ARFF file
Remember to download programs supporting ARFF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Weka with ARFF files
If the application is or has been freshly installed, but the ARFF file still does not use the Weka program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the ARFF file with the Weka program.
Step 3. Update Weka to the latest version
The fault may also lie with the Weka program, it is possible that Weka Attribute-relation Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the University of Waikato page and install.
Step 4. Check for the following problems with the ARFF file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. Usually this applies to ARFF files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our ARFF file. As a result of the scan, sometimes it is not possible to recover ARFF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the ARFF files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged ARFF files. The easiest way is to restore the file from a backup, if there is one, or contact University of Waikato
When reading, a message appears that the file was encrypted or corrupted. The encrypted ARFF files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move ARFF to a different directory.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the ARFF file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
