FILELIBRARY

A C library for file and directory operations on Windows systems, providing functions for both ANSI (A) and Unicode (W) character sets. This project was created in 2020. It is an older project and does not reflect my current coding standards.

Overview

FileLibrary is a Windows-specific DLL that offers an API for common file system operations:

• File and directory existence checking
• File and directory creation and deletion
• File and directory copying and moving
• File and directory renaming
• Size querying for files and directories

Data Structures

FileptrA

typedef struct FileptrA
{
    HANDLE File;
    char path[200];
    BY_HANDLE_FILE_INFORMATION basicInfo;
} FileptrA;

FileptrW

typedef struct FileptrW
{
    HANDLE File;
    TCHAR path[200];
    BY_HANDLE_FILE_INFORMATION basicInfo;
} FileptrW;

API Reference

Function	Description
dirExistsA / dirExistsW	Check if a directory exists
CreateFileptrA / CreateFileptrW	Create a file or directory
OpenFileptrA / OpenFileptrW	Open a file or directory into a Fileptr
CloseFileptrA / CloseFileptrW	Close a Fileptr handle
RemoveFileptrA / RemoveFileptrW	Delete a file or directory via Fileptr
DeleteFolderA / DeleteFolderW	Recursively delete a directory by path
ReNameFileptrA / ReNameFileptrW	Rename a file or directory via Fileptr
CopyFileptrA / CopyFileptrW	Copy a file or directory via Fileptr
TransferFileptrA / TransferFileptrW	Move a file or directory via Fileptr
GetSizePtrA / GetSizePtrW	Get size (bytes) of a file or directory via Fileptr

Usage Notes

• Functions suffixed with A accept ANSI strings (char*)
• Functions suffixed with W accept Unicode strings (TCHAR*/wchar_t*)
• Path strings are limited to 200 characters
• Directory name strings are limited to 150 characters
• OpenFileptrA/OpenFileptrW with dir = true will create the directory if it does not exist

Compatibility

Windows only. Requires linking against the Windows API.
