privatefungetUriFromPath(displayName: String): Uri? {
        val photoId: Longval photoUri = MediaStore.Images.Media.getContentUri("external")
        val projection = arrayOf(MediaStore.Images.ImageColumns._ID)
        val cursor = contentResolver.query(
            photoUri,
            projection,
            MediaStore.Images.ImageColumns.DISPLAY_NAME + " LIKE ?",
            arrayOf(displayName),
            null
        )!!
        cursor.moveToFirst()
        val columnIndex = cursor.getColumnIndex(projection[0])
        photoId = cursor.getLong(columnIndex)
        cursor.close()
        return Uri.parse("$photoUri/$photoId")
    }

if you want you can add relative path too to find at specific location

check using file name

privatefunisExist(){
        val pathOfImage=getUriFromPath("myimage.png")
        val isExist = try {
            val i= pathOfImage?.let { contentResolver.openInputStream(it) }
            i != null
        }
        catch (e: IOException) {
            e.printStackTrace()
            false
        }
        if (!isExist) {
            // do whatever u want
        }
    }

this solution give exception when file not found and try to openstream.

Solution-2

In this solution I did save my files into Android\media\com.yourpackge\ directory

privatefunisExist(){
        val path = this.externalMediaDirs.first()
        val folder = File(path, getString(R.string.app_name))
        if (!folder.exists()) folder.mkdirs()
        val  file = File(folder, "myimage.png")

        if (!file.exists()) {
            // save your files or do whatever you want// use this for show files into gallery
            MediaScannerConnection.scanFile(this, arrayOf(file.absolutePath), null,
                object : MediaScannerConnection.OnScanCompletedListener {
                    overridefunonScanCompleted(path: String, uri: Uri?) {
                        Log.e("scann--","Finished scanning $path")
                    }
                })
        }
    }

Now I want to move my files from older getExternalStorageDirectory folder to Android\media\com.yourpackge\ directory in android 11 like whatsapp did without asking any permission.

EDIT - 1

I'm able to move my folder to new on using kotlin Utils class

sourcefolder.copyRecursively(newfolder,true)

privatefuncopyFiles(){
        val path = this.externalMediaDirs.first()
        val folder = File(path, getString(R.string.app_name))
        if (!folder.exists()) folder.mkdirs()
        val sourcefolder = File(Environment.getExternalStorageDirectory().toString() + "/"
                +"Supreme")
        sourcefolder.copyRecursively(folder,true)

    }
