DCT File Extension

Dictionary Format

What is DCT file?

Dictionary Files, known as Dictionary Files, are saved with the .DCT extension. These are primarily text format files, capable of storing a variety of data. They can have varied syntax, sometimes defined at the beginning of the file, in its header. .DCT files can also be in ZIP package format. In such a case, a single file may contain one or several text files as well as the rules describing them.

Possible uses of files with the .DCT extension

Files with the .DCT extension serve as a sort of word database. They may, but do not have to be linked to definitions or translations. It all depends on the format and the program that uses the files. For example:

  • a dictionary allowing for the verification of writing correctness, belonging to the dictionary,
  • a translator enabling the translation of words,
  • an encyclopedic application providing the possibility to check definitions.

The way records are saved in .DCT files depends on the software's specificity. They are most commonly separated by a new line character, whereas separate dictionaries, for example in another language, are found in separate files.
