What is FAI file?

The FAI file has been categorized as Misc Files. In addition to this file, the Misc Files category includes 6033 related files. FASTA Index Format appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. It is recommended to use FASTA to handle this file. This is a program created by University of Virginia.

How to open FAI file?

The most common problem when using FASTA Index Format is that a specific FAI is not associated with the program. This is manifested by the fact that FAI files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the FAI 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 FASTA

An often overlooked issue is to make sure that FASTA is installed on the computer. To do this, enter the name FASTA into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open FAI files.

Programs to open FAI file

Remember to download programs supporting FAI files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of FASTA with FAI files

If, despite the installed application, the FAI file does not start in the FASTA application, you must create a file 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. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the FAI file with the FASTA program.

Step 3. Update FASTA to the latest version

If, however, after binding FASTA with FASTA Index Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the University of Virginia website and install the latest version.

Step 4. Check for the following problems with the FAI 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. This suggests truncating the FAI file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the FAI file that we want to open. As a result of the scan, sometimes it is not possible to recover FAI files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of FAI file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular FAI file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
The program can also signal the fact of encryption. The encrypted file FAI except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move FAI to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file FAI to close. However, some background programs may block the FAI file while scanning. If this does not work either, restart the device.
