Can't move neither mp3 nor jpg with Files.move in java -

-

i finished reading question of same type unfortunaetly didn't me lot.

i have problem moving files mp3 , jpg folder created before trying move files.

here's code:

public class filessorter {    private string extension;     public filessorter(string ext) {       this.setextension(ext);    }     public void setextension(string extension) {       this.extension = extension;    }     public void sortit(path path, path filename) {       string stringpath = path.tostring();        switch (this.extension) {         case "folder":             return;         case "txt":             file folderdocs = new file(stringpath + ("\\documents"));             if (!folderdocs.exists()) {                 folderdocs.mkdir();             }             path sourcedocs = path.resolve(filename);             path targetdocs = folderdocs.topath().resolve(filename);             try {                 files.move(sourcedocs, targetdocs, atomic_move);             } catch (ioexception e) {                 system.out.println("moving failed.");             }             break;         case "mp3":         case "wma":         case "ogg":             file foldermsc = new file(stringpath + ("\\music"));             if (!foldermsc.exists()) {                 system.out.println("created folder");                 foldermsc.mkdir();             }             path sourcemsc = path.resolve(filename);             path targetmsc = foldermsc.topath().resolve(filename);             system.out.println(sourcemsc);             system.out.println(targetmsc);             try {                 files.move(sourcemsc, targetmsc, replace_existing);             } catch (ioexception e) {                 system.out.println("moving failed.");             }             break;        ... }

and fragment i'm calling method:

while (true) {             key = foldermonitor.take();              kind<?> tmp;              (watchevent<?> eventsinfolder : key.pollevents()) {                 tmp = eventsinfolder.kind();                  if (tmp == entry_create) {                     path recentlycreatedpath = ((watchevent<path>) eventsinfolder).context();                     system.out.println("new path created: " + recentlycreatedpath);                     type = this.givemetype(string.valueof(recentlycreatedpath));                     this.actwithfile(type, recentlycreatedpath);                 } else if (tmp == entry_delete) {                     system.out.println("path deleted: " + ((watchevent<path>) eventsinfolder).context());                 } else if (tmp == overflow) {                     continue;                 }             }              if (!key.reset()) {                 break;             }             timethen = system.currenttimemillis();             if(timethen - timenow > 120000) {                 break;             }         }

as i've said, when try move txt works, when try move mp3 says "moving failed."

thank in advance answering question or giving other tips find such information.

edit: here's code call sortit method (sorry not making earlier).

private void actwithfile (string type, path pathtofile) {     filessorter fs = new filessorter(type);     fs.sortit(this.pathdirectory, pathtofile); }
