[英]How to search entire hard drive for a specific file (Java Eclipse)?
public static void fileSearcher() throws IOException {
File dire = new File ("C:/");
String[] allFile = dire.list();
for (int i = 0;i<10;i++) {
String FilIn = allFile[i]; // here is where I need to scan entire pc for file
if(FilIn.equals("eclipse.exe")){
System.out.println("Found Eclipse!");
break;
}
else {
System.out.println("Eclipse not found on local drive.");
}
是否有一種簡單的方法可以掃描整個 HHD/SSD 以查找特定文件?
這將為您完成這項工作,並且在有多個驅動器或分區時也可以使用。 它還將搜索具有相同名稱的其他文件。
import java.io.File;
import javax.swing.filechooser.FileSystemView;
public class HardDiskSearcher {
private static boolean fileFound = false;
private static String searchTerm = "eclipse.exe";
public static void main(String[] args) {
fileFound = false;
File[] systemRoots = File.listRoots();
FileSystemView fsv = FileSystemView.getFileSystemView();
for (File root: systemRoots) {
if (fsv.getSystemTypeDescription(root).equals("Local Disk")) {
File[] filesFromRoot = root.listFiles();
recursiveSearch(searchTerm, filesFromRoot);
}
}
System.out.println("File you searched for was found? : " + fileFound);
}
private static void recursiveSearch(String searchTerm, File... files) {
for (File file: files) {
if (file.isDirectory()) {
File[] filesInFolder = file.listFiles();
if (filesInFolder != null) {
for (File f : filesInFolder) {
if (f.isFile()) {
if (isTheSearchedFile(f, searchTerm)) {
fileFound = true;
}
}
}
for (File f : filesInFolder) {
if (f.isDirectory()) {
recursiveSearch(searchTerm, f);
}
}
}
}
else if (isTheSearchedFile(file, searchTerm)) {
fileFound = true;
}
}
}
private static boolean isTheSearchedFile(File file, String searchTerm) {
if (file.isFile() && (searchTerm.equals(file.getName())) ) {
System.out.println("The file you searched for has been found! " +
"It was found at: " + file.getAbsolutePath());
return true;
}
return false;
}
}
我不是 100% 確定為什么這里需要 if 語句(filesInFolder.= null),但我懷疑 Windows 在嘗試列出來自特定系統文件夾或其他內容的文件時返回 null。
