An Overview of the File-System Functions

File Input/Output (File I/O) is a fundamental aspect of computing, and while FileMaker has some built-in capabilities, they may not always meet all your needs. Therefore, we've included robust file-system functions in ACF to empower your FileMaker solutions with versatile file operations.

In addition to the basic file operations like opening, closing, reading, and writing to files, ACF offers a comprehensive suite of file-system functions:

• Select File Dialogue: A convenient function to open a system dialog for selecting files, making it easy for users to choose files for processing.

• Select Directory Dialogue: Similar to the file dialogue but designed for selecting directories (folders). This function simplifies directory selection within your solutions.

• Choose File Name and Directory for Saving: A function that opens a system dialog to allow users to specify a file name and directory for saving, ensuring files are stored precisely where they want them.

• Copy File: Easily duplicate files with this function. Copy a file from one location to another within your file system.

• Move File: Move files from one location to another using this function. Efficiently organize your files and directories.

• Delete File: Remove unwanted files from your file system using this function. Keep your storage clean and clutter-free.

• File Size: Determine the size of a file with this function. Useful for monitoring and managing storage usage.

• List Files in a Directory: Retrieve a list of files contained within a directory. This function simplifies tasks involving multiple files in a folder.

• Get Document Directory: Find the document directory specific to your platform (e.g., macOS, Windows, iOS) with this function.

• Get Desktop Directory: Quickly access the desktop directory location for your platform.

• Get Temporary Directory: Retrieve the temporary directory path, typically used for temporary file storage.

• Get Home Directory: Get the user's home directory path, ensuring access to a user's personal storage space.

The "Create File" function is not necessary because when you open a file for writing, and it doesn't exist, it will be created automatically. This approach simplifies file creation.

It's worth noting that ACF provides an efficient method for handling file operations. When you open a file using ACF, you receive a file ID, which you can assign to an integer variable. This file ID allows you to interact with the file in multiple function calls, such as reading and writing. You don't need to close the file immediately after opening it; you can continue to work with it and close it explicitly when you're finished.

ACF uses POSIX paths (Unix paths) for file operations, simplifying path handling. There's no need to deal with various path syntaxes like "file:///" or "filemac://"; you can work with standard POSIX paths directly.

In summary, ACF's file-system functions provide a powerful toolkit for managing files and directories within your FileMaker solutions efficiently. Whether you need to read, write, copy, move, or delete files, or interact with directories, ACF simplifies the process and makes file operations seamless.
