1. List of Properties of the .ACCFT File Format Intrinsic to Its File System

Based on available documentation, the .ACCFT file format is a binary format used by Microsoft Access for data type templates, which define field structures for database tables. However, detailed internal specifications, such as header structures or data encoding, are not publicly available from Microsoft or other sources. The following properties are derived from public descriptions and represent the known characteristics intrinsic to the format as it interacts with file systems:

• File Extension: .accft (case-insensitive, typically lowercase).
• MIME Type: application/msaccess.
• File Category: Database template file.
• File Type: Binary file (not human-readable; requires specific software for interpretation).
• Associated Software: Microsoft Access 2007 and later versions (primary); no known open-source alternatives for full support.
• Purpose and Content: Stores definitions of data types and properties for table fields, enabling reuse in database design (e.g., predefined fields like names, addresses, or dates with associated formats and validation rules).
• Storage Location (Typical): In the Microsoft Access Templates folder, such as %APPDATA%\Microsoft\Templates\Access\ or program installation directories.
• File System Attributes: Standard file system metadata applies (e.g., creation date, modification date, file size, permissions), but these are not unique to the format; the file is treated as an opaque binary blob by the operating system.
• Compatibility: Compatible with Windows file systems (NTFS, FAT32); cross-platform use limited by dependency on Microsoft Access.
• Size Characteristics: Typically small (kilobytes), as they contain template metadata rather than full database content.
• Security Considerations: As a binary format, it may contain embedded scripts or macros if part of a larger Access ecosystem, potentially subject to execution restrictions in file systems with security features.

These properties focus on how the format is handled at the file system level, including identification and association. No deeper structural details (e.g., byte offsets, signatures) are documented publicly.

2. Two Direct Download Links for .ACCFT Files

After extensive searches across web sources, including Microsoft documentation, file extension databases, and sample repositories, no publicly available direct download links for .ACCFT files were identified. These files are typically created and managed within Microsoft Access rather than distributed as standalone samples. They are not commonly shared online due to their specialized nature and proprietary format. If required, such files can be generated manually in Microsoft Access by saving field selections as data type templates via the ribbon interface.

3. Ghost Blog Embedded HTML JavaScript for Drag-and-Drop .ACCFT File Dump

The term "ghost blog" appears to refer to a simple, standalone HTML page (perhaps akin to a static blog post) with embedded JavaScript for file handling. Below is a complete HTML document that allows drag-and-drop of a .ACCFT file. Since the format is binary and undocumented, the script reads the file as binary data and dumps basic file system properties (e.g., name, size, type) to the screen. It cannot decode internal properties due to the lack of specifications.

This can be saved as an HTML file and opened in a browser for use.

4. Python Class for Handling .ACCFT Files

Since the .ACCFT format specifications are not publicly available, a complete decode/read/write implementation is not feasible. The class below opens the file as binary, reads its content, prints basic file system properties, and provides placeholder methods for decode/write operations. It uses standard Python libraries.

import os
import datetime
import binascii

class AccftHandler:
    def __init__(self, filepath):
        self.filepath = filepath
        self.data = None

    def open_and_read(self):
        """Open and read the binary file."""
        if not os.path.exists(self.filepath) or not self.filepath.lower().endswith('.accft'):
            raise ValueError("Invalid .ACCFT file path.")
        with open(self.filepath, 'rb') as f:
            self.data = f.read()

    def decode(self):
        """Placeholder for decoding; format unknown."""
        if self.data is None:
            raise ValueError("File not read.")
        print("Decoding not possible: Format specifications unavailable.")
        # Example: Print hex preview
        print("Binary Preview (Hex, first 32 bytes):", binascii.hexlify(self.data[:32]).decode('utf-8'))

    def write(self, output_path):
        """Write the binary data to a new file."""
        if self.data is None:
            raise ValueError("No data to write.")
        with open(output_path, 'wb') as f:
            f.write(self.data)
        print(f"File written to {output_path}")

    def print_properties(self):
        """Print file system properties."""
        if not os.path.exists(self.filepath):
            raise ValueError("File not found.")
        stats = os.stat(self.filepath)
        print("File Properties:")
        print(f"  - Path: {self.filepath}")
        print(f"  - Size: {stats.st_size} bytes")
        print(f"  - Created: {datetime.datetime.fromtimestamp(stats.st_ctime).isoformat()}")
        print(f"  - Modified: {datetime.datetime.fromtimestamp(stats.st_mtime).isoformat()}")
        print(f"  - MIME Type: application/msaccess")
        print(f"  - Extension: .accft")

# Example usage:
# handler = AccftHandler('example.accft')
# handler.open_and_read()
# handler.print_properties()
# handler.decode()
# handler.write('output.accft')

5. Java Class for Handling .ACCFT Files

Similarly, due to unavailable specifications, the Java class handles binary reading and basic properties. It uses standard Java I/O.

import java.io.*;
import java.nio.file.*;
import java.nio.file.attribute.*;
import java.time.Instant;

public class AccftHandler {
    private String filepath;
    private byte[] data;

    public AccftHandler(String filepath) {
        this.filepath = filepath;
    }

    public void openAndRead() throws IOException {
        Path path = Paths.get(filepath);
        if (!Files.exists(path) || !filepath.toLowerCase().endsWith(".accft")) {
            throw new IllegalArgumentException("Invalid .ACCFT file path.");
        }
        data = Files.readAllBytes(path);
    }

    public void decode() {
        if (data == null) {
            throw new IllegalStateException("File not read.");
        }
        System.out.println("Decoding not possible: Format specifications unavailable.");
        // Example: Print hex preview
        System.out.print("Binary Preview (Hex, first 32 bytes): ");
        for (int i = 0; i < Math.min(32, data.length); i++) {
            System.out.printf("%02X ", data[i]);
        }
        System.out.println();
    }

    public void write(String outputPath) throws IOException {
        if (data == null) {
            throw new IllegalStateException("No data to write.");
        }
        Files.write(Paths.get(outputPath), data);
        System.out.println("File written to " + outputPath);
    }

    public void printProperties() throws IOException {
        Path path = Paths.get(filepath);
        if (!Files.exists(path)) {
            throw new IllegalArgumentException("File not found.");
        }
        BasicFileAttributes attrs = Files.readAttributes(path, BasicFileAttributes.class);
        System.out.println("File Properties:");
        System.out.println("  - Path: " + filepath);
        System.out.println("  - Size: " + attrs.size() + " bytes");
        System.out.println("  - Created: " + Instant.ofEpochMilli(attrs.creationTime().toMillis()).toString());
        System.out.println("  - Modified: " + Instant.ofEpochMilli(attrs.lastModifiedTime().toMillis()).toString());
        System.out.println("  - MIME Type: application/msaccess");
        System.out.println("  - Extension: .accft");
    }

    // Example usage:
    // public static void main(String[] args) throws IOException {
    //     AccftHandler handler = new AccftHandler("example.accft");
    //     handler.openAndRead();
    //     handler.printProperties();
    //     handler.decode();
    //     handler.write("output.accft");
    // }
}

6. JavaScript Class for Handling .ACCFT Files

This Node.js-compatible class uses the 'fs' module for file operations. Decoding is placeholder-only.

const fs = require('fs');
const path = require('path');

class AccftHandler {
    constructor(filepath) {
        this.filepath = filepath;
        this.data = null;
    }

    openAndRead() {
        if (!fs.existsSync(this.filepath) || !this.filepath.toLowerCase().endsWith('.accft')) {
            throw new Error('Invalid .ACCFT file path.');
        }
        this.data = fs.readFileSync(this.filepath);
    }

    decode() {
        if (!this.data) {
            throw new Error('File not read.');
        }
        console.log('Decoding not possible: Format specifications unavailable.');
        // Example: Print hex preview
        let hex = '';
        for (let i = 0; i < Math.min(32, this.data.length); i++) {
            hex += this.data[i].toString(16).padStart(2, '0') + ' ';
        }
        console.log('Binary Preview (Hex, first 32 bytes):', hex.trim());
    }

    write(outputPath) {
        if (!this.data) {
            throw new Error('No data to write.');
        }
        fs.writeFileSync(outputPath, this.data);
        console.log(`File written to ${outputPath}`);
    }

    printProperties() {
        if (!fs.existsSync(this.filepath)) {
            throw new Error('File not found.');
        }
        const stats = fs.statSync(this.filepath);
        console.log('File Properties:');
        console.log(`  - Path: ${this.filepath}`);
        console.log(`  - Size: ${stats.size} bytes`);
        console.log(`  - Created: ${stats.birthtime.toISOString()}`);
        console.log(`  - Modified: ${stats.mtime.toISOString()}`);
        console.log(`  - MIME Type: application/msaccess`);
        console.log(`  - Extension: .accft`);
    }
}

// Example usage:
// const handler = new AccftHandler('example.accft');
// handler.openAndRead();
// handler.printProperties();
// handler.decode();
// handler.write('output.accft');

7. C++ Class for Handling .ACCFT Files

Assuming C++ (as C does not have classes natively), this class uses standard I/O. It handles binary files but cannot decode internals.

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <ctime>
#include <sys/stat.h>

class AccftHandler {
private:
    std::string filepath;
    std::vector<char> data;

public:
    AccftHandler(const std::string& fp) : filepath(fp) {}

    void openAndRead() {
        if (filepath.substr(filepath.find_last_of(".") + 1) != "accft") {
            throw std::invalid_argument("Invalid .ACCFT file path.");
        }
        std::ifstream file(filepath, std::ios::binary);
        if (!file) {
            throw std::runtime_error("File not found.");
        }
        data.assign((std::istreambuf_iterator<char>(file)), std::istreambuf_iterator<char>());
    }

    void decode() {
        if (data.empty()) {
            throw std::runtime_error("File not read.");
        }
        std::cout << "Decoding not possible: Format specifications unavailable." << std::endl;
        // Example: Print hex preview
        std::cout << "Binary Preview (Hex, first 32 bytes): ";
        for (size_t i = 0; i < std::min<size_t>(32, data.size()); ++i) {
            printf("%02X ", static_cast<unsigned char>(data[i]));
        }
        std::cout << std::endl;
    }

    void write(const std::string& outputPath) {
        if (data.empty()) {
            throw std::runtime_error("No data to write.");
        }
        std::ofstream out(outputPath, std::ios::binary);
        out.write(data.data(), data.size());
        std::cout << "File written to " << outputPath << std::endl;
    }

    void printProperties() {
        struct stat stats;
        if (stat(filepath.c_str(), &stats) != 0) {
            throw std::runtime_error("File not found.");
        }
        std::cout << "File Properties:" << std::endl;
        std::cout << "  - Path: " << filepath << std::endl;
        std::cout << "  - Size: " << stats.st_size << " bytes" << std::endl;
        std::cout << "  - Created: " << std::asctime(std::localtime(&stats.st_ctime));
        std::cout << "  - Modified: " << std::asctime(std::localtime(&stats.st_mtime));
        std::cout << "  - MIME Type: application/msaccess" << std::endl;
        std::cout << "  - Extension: .accft" << std::endl;
    }
};

// Example usage:
// int main() {
//     try {
//         AccftHandler handler("example.accft");
//         handler.openAndRead();
//         handler.printProperties();
//         handler.decode();
//         handler.write("output.accft");
//     } catch (const std::exception& e) {
//         std::cerr << e.what() << std::endl;
//     }
//     return 0;
// }
