DCTファイルとは?

A DCT file is a dictionary data file used by various dictionary, translation, and word processing applications. It stores a list of words and may also include related information such as definitions, translations, or usage data. Applications reference this file to support features, such as spell checking, word lookup, or language assistance, rather than for direct user interaction.

詳細情報

The format of a DCT file depends on the software that uses it. Some programs store data in plain text, while others use a binary format for faster lookups and improved performance. Because there is no single standard for DCT files, the internal structure and contents vary by application.

注: Software developers, language tool vendors, and end users who work with multilingual content or text-heavy documents are most likely to encounter DCT files.

DCTファイルの開き方

DCT files are not meant to be opened by users. Instead, the applications they are packaged with, such as QuarkXPress, automatically open them.

In some cases, you can view a plain–text–based DCT file with a text editor, but the contents may not be easy to interpret. To properly use or modify a DCT file, users should open it within the original dictionary, translation, or word processing program that created it.

A DCT file is a digital audio file that stores dictation, typically recorded speech, in the Dictation Audio (DCT) format used by NCH Software, such as Scribe and Dictate. It contains audio data that may be compressed and encrypted, along with metadata about the recording.

詳細情報

NCH Software developed the DCT format for dictation devices and software that capture spoken notes, such as those used in professional or medical environments. Medical professionals, lawyers, transcriptionists, and office staff who need to create, manage, or transcribe voice recordings are common users of the format.

The DCT format includes a dictation header that contains metadata about the recording, such as date, time, author, or device information. Many DCT files can also be encrypted, which helps protect sensitive information in fields like healthcare or legal work. The combination of compression, metadata, and optional encryption makes the format helpful for securely recording, storing, and transferring dictation files while complying with confidentiality regulations.

DCTファイルの開き方

You can open DCT files with various software, such as NCH Express Scribe, NCH Express Dictate, and NCH Switch. NCH WavePad also opens DCT files.

Visual FoxPro Database Memo

A DCT file is a memo file used by Microsoft Visual FoxPro to store descriptive text associated with a Visual FoxPro database container (.DBC file). It contains notes, comments, and other written information that developers add to document the database, which describe tables, fields, relationships, or design decisions that are not stored directly in the database structure. Visual FoxPro saves the DCT file in a binary memo format and manages it automatically as part of the database container system.

詳細情報

Each DCT file works together with a corresponding FoxPro Database DBC file and its related Database Index .DCX file. The database engine uses these files as a set, reading the memo data from the DCT file when displaying or editing database descriptions inside the development environment.

Software developers and database administrators who work with Visual FoxPro databases are the most likely to encounter DCT files. However, Visual FoxPro is no longer actively developed (its final version was Visual FoxPro 9.0, released in 2007).

DCTファイルの開き方

DCT files are not meant to be opened. Instead, Microsoft Visual FoxPro reads the DCT file automatically when you open its associated DBC database.

AutoCAD Dictionary File

A DCT file is a dictionary file used by Autodesk AutoCAD, a computer-aided design (CAD) application. It stores a list of valid words for a specific language that AutoCAD's built-in spell-checking tools use to review text elements in drawings, such as annotations, notes, dimensions, and labels. DCT files help the software identify misspelled words and suggest corrections while users are editing text within a drawing.

詳細情報

AutoCAD loads DCT files automatically when its spelling features are enabled. While the DCT file provides the base vocabulary, AutoCAD allows users to extend spell-checking behavior by adding project-specific or technical terms through custom user dictionaries, which are stored separately in .CUS files. This separation keeps standard language data distinct from user-defined additions.

DCTファイルの開き方

DCT files are not meant to be opened. Instead, Autodesk AutoCAD references DCT files to load the dictionaries. Opening it in a text editor may show unreadable or incomplete data, and changes should be made through AutoCAD's spelling and dictionary management tools to avoid corruption.

DeSmuME ROM Cheats File

A DCT file is a cheats file used by DeSmuME, an open-source emulator for Nintendo DS (NDS) games. It stores cheat codes that modify how a game behaves when it runs in the emulator, with changes affecting gameplay elements, such as health, items, scores, or unlocked features. DeSmuME loads the DCT file alongside a specific game (often an .NDS game)to apply the selected cheats during emulation.

詳細情報

DCT files list cheat entries, including their corresponding memory addresses and values, in a text-based format. Each DCT file is typically associated with a single NDS game and matches that game's unique identifier.

DeSmuME reads the DCT file at runtime and allows players to turn individual cheats on or off through its built-in cheat management interface. This format supports common Nintendo DS cheat systems, such as Action Replay–style codes.

注: DCT files are not part of the original game software and are intended for use only within the DeSmuME emulator, not on real Nintendo DS hardware.

DCTファイルの開き方

You can open DCT files with DeSmuME. To open a DCT file, place it in the appropriate cheats folder recognized by DeSmuME, then load the corresponding game in the emulator. You can view and manage cheats through DeSmuME’s cheat menu.

Since DCT files are text-based, you can also open them with a plain text editor to view or edit cheat entries. However, if you modify the file incorrectly, you will create invalid codes.

Need for Speed II was the second game released as part of Electronic Arts' Need for Speed franchise. It allowed players to race a number of exotic cars on racetracks located around the world. EA released Need for Speed II in 1997 and has since released over 20 additional Need for Speed games.

DCT movies feature real-life footage of cars that players can unlock within Need for Speed II. Players could watch these movies while learning more about the cars they'd acquired.
