java - Can't make Files and Folders -

so i'm working on simple windows explorer replacement. want add ability create folders , files. reason, works when i'm in root or c:/ folder, it's somewhere else (for example c:\program files (x86)) doesn't work. either java.io.ioexception: access denied when create file , when try create folder, no exception comes up, no folder created.

this code new file:

string location = getpath(); string name = joptionpane.showinputdialog("fill in name of new file. \ndon't forget add file type (.txt, .pdf).", null); if(name == null){  } else {     file newfile = new file(location + "\\" + name);     boolean flag = false;     try {         flag = newfile.createnewfile();     } catch (ioexception io) {         jframe messagedialog = new jframe("error!");         joptionpane.showmessagedialog(messagedialog, "file creation failed following reason: \n" + io);         }     } 

this code new folder:

string location = getpath(); string name = joptionpane.showinputdialog("fill in name of new folder.", null); if(name == null){  } else {     file newfolder = new file(location + "\\" + name);     boolean flag = false;     try {         flag = newfolder.mkdir();     } catch (securityexception se) {         jframe messagedialog = new jframe("error!");         joptionpane.showmessagedialog(messagedialog, "folder creation failed following reason: \n" + se);         }     } 

i'm stuck right , have no idea i'm doing wrong rid of access denied error.

short explenation of how program works: program shows list of folders , files selected file. file field in class jxplorefile called "currentfile", behaves same file. when browsing through folders, currentfile set new jxplorefile, containing new folder in file. when creating new folder/file, program ask path user browsing in method getpath().

thanks help!

image of program:

before try make i/o operation check if have permission

go parent directory (your case location)

then like

file f = new file(location);      if(f.canwrite()) {             /*your full folder creation code here */     } else {      }
