Ada banyak file yang terdapat dalam
komputer, seperti file system, program, dan dokumen dari beberapa aplikasi.
Untuk memudahkan pengenalan file-file tersebut, setiap software memiliki
identitas masing-masing untuk pemberian nama file. Identitas ini disebut dengan
ekstensi.
Setiap file mempunyai akhiran tiga huruf
setelah titik atau disebut dengan ekstensi (ekstension). Ekstensi file
berfungsi untuk memudahkan user dalam mengindentifikasi filenya.
Ekstensi file (file extension) adalah huruf
terakhir setelah titik pada nama file dan menunjukan jenis file. Misalkan nama
file kamus.doc mempunyai ekstensi file .doc, dan merupakan file dokumen yang
dibuat dengan MS Word. Ekstensi file dapat dikatakan sebagai pengenal jenis
file.
Kita pernah memperhatikan nama-nama file
(berkas) yang ada di komputer? Nah, pada nama-nama file (berkas) tersebut
banyak akhiran file (berkas) yang mungkin belum kita ketahui artinya. Misalnya
saja kita membuat file yang dibuat dengan program aplikasi Microsoft Word
kemudian disimpan dengan nama "contoh". Maka jika kita lihat nama
file tersebut dari windows explorer akan menjadi "contoh.doc". Nah,
akhiran .doc inilah yang disebut dengan ekstensi file (nama ekstensi berkas).
Jadi, dengan kata lain, filename extension
atau akhiran nama berkas digunakan untuk menandakan isi atau format dari berkas
tersebut. Sebagai contoh .GIF menunjukkan berkas image (gambar) yang
menggunakan format GIF dan seterusnya.
Ekstensi File adalah salah satu dari
metadata yang menjelaskan informasi tentang file (data fisik dari suatu file).
Ekstensi file ini sangat penting karena berhubungan dengan registry yang
menentukan dengan software/aplikasi yang tepat untuk membuka file tersebut
(dalam properties file diberithukan informasi Open with, yang memberitahukan
aplikasi yang tepat untuk membuka file tersebut.
Berikut
ini adalah beberapa contoh Ekstensi File sesuai Tipe Filenya masing masing.
