// Real-time search with hierarchical filtering
const filteredFiles = useMemo(() => {
if (!searchQuery.trim()) return files;
const query = searchQuery.toLowerCase();
const matchingFiles = new Map<string, FileNode>();
// Include matching files and their parent folders
for (const [path, file] of files) {
if (file.name.toLowerCase().includes(query)) {
matchingFiles.set(path, file);
// Include parent hierarchy
let currentPath = file.parent;
while (currentPath && currentPath !== '/') {
const parentFile = files.get(currentPath);
if (parentFile) {
matchingFiles.set(currentPath, parentFile);
currentPath = parentFile.parent;
}
}
}
}
return matchingFiles;
}, [files, searchQuery]);// Comprehensive clipboard management
const [clipboardItem, setClipboardItem] = useState<ClipboardItem | null>(null);
const handleCopy = useCallback((file: FileNode) => {
setClipboardItem({ file, operation: 'copy' });
}, []);
const handlePaste = useCallback(async (targetPath: string) => {
if (!clipboardItem) return;
const { file, operation } = clipboardItem;
// Handle copy/cut operations with proper file management
}, [clipboardItem, createFile, createFolder, renameFile]);// Intelligent file type detection
export const getFileTypeIcon = (fileName: string, fileType: 'file' | 'folder', isExpanded?: boolean) => {
if (fileType === 'folder') {
return isExpanded ? LucideFolderOpen : LucideFolder;
}
// Check special patterns first
for (const { pattern, icon } of specialFilePatterns) {
if (pattern.test(fileName)) return icon;
}
// Check file extensions
const extension = fileName.split('.').pop()?.toLowerCase();
return fileExtensionIcons[extension] || LucideFile;
