How to Check If a File Exists in Documents Folder

How to check if a file exists in Documents folder?

Swift 3:

let documentsURL = try! FileManager().url(for: .documentDirectory,
                                          in: .userDomainMask,
                                          appropriateFor: nil,
                                          create: true)

... gives you a file URL of the documents directory. The following checks if there's a file named foo.html:

let fooURL = documentsURL.appendingPathComponent("foo.html")
let fileExists = FileManager().fileExists(atPath: fooURL.path)

Objective-C:

NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];

NSString* foofile = [documentsPath stringByAppendingPathComponent:@"foo.html"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];

    if let pathComponent = url.appendingPathComponent("nameOfFileHere") {
        let filePath = pathComponent.path
        let fileManager = FileManager.default
        if fileManager.fileExists(atPath: filePath) {
            print("FILE AVAILABLE")
        } else {
            print("FILE NOT AVAILABLE")
        }
    } else {

    let url = URL(fileURLWithPath: path)

    let filePath = url.appendingPathComponent("nameOfFileHere").path
    let fileManager = FileManager.default
    if fileManager.fileExists(atPath: filePath) {
        print("FILE AVAILABLE")
    } else {
        print("FILE NOT AVAILABLE")

    let path = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
    let url = NSURL(fileURLWithPath: path)
    let filePath = url.URLByAppendingPathComponent("nameOfFileHere").path!
    let fileManager = NSFileManager.defaultManager()
    if fileManager.fileExistsAtPath(filePath) {
        print("FILE AVAILABLE")
    } else {
        print("FILE NOT AVAILABLE")

How to check if a file exists in a folder?

This is a way to see if any XML-files exists in that folder, yes.

To check for specific files use File.Exists(path), which will return a boolean indicating wheter the file at path exists.

How to check if multiple files exist in documents directory? (Swift)

Write a method for example

func checkFiles(with fileNames: [String] {
    for fileName in fileNames {
        let fileURL = documentsDirectoryURL.appendingPathComponent(fileName) 
        if !FileManager.default.fileExists(atPath: fileURL.path) {
            removeImage(itemName: fileName, fileExtension: "jpg")
        } else {
            print("There was no image to remove at", fileURL)
        }
    }
}

and call it

let fileNames = ["savedpicture1", "savedpicture2", "savedpicture3",  "savedpicture4"] 
checkFiles(with: fileNames)

check if file exists in project folder

The only way to know whether this is available or not at runtime is by using NSBundle.

NSString *path = [[NSBundle mainBundle] pathForResource:@"my_audio" ofType:@"mp3"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:path];

In fileExists you know if it is available.

Be sure to check the build-phases if the file is copied to the bundle.

Check if a file exists in the documents directory

BOOL isMyFileThere = [[NSFileManager defaultManager] fileExistsAtPath:myFilePath];

Check in NSFileManager Documentation .

PHP Checking if a file exists in a directory

Your code is wrong. This is much simpler and easier to understand.

$directory = "files/";
$counter = 0;
$name = $_FILES['filename']['name'];
while(file_exists($directory . $name)){
    $counter++;
    $name = $_FILES['filename']['name'] . $counter;
}

Also your code does not generate file.txt -> file1.txt but file.txt -> file.txt1 so does this one. To generate it properly play with the extension and the name.
