im running program visual studio 2012 pro admin. ran visual studio admin.

for example exception error on line:

directory.createdirectory(outputtext); 

unauthorizedaccessexception access path 'c:\users\bout0_000\appdata\local\outputfiles\outputtext' denied.

and windows self throw me window in middle of screen say: location not available , inside see description check network check if disk inserted....etc.

1. if im running program admin why dont have access ?
2. is there directories maybe can use have access users when under admin rights ? or maybe without admin rights ? instead this:

c:\users\bout0_000\appdata\local\outputfiles\outputtext

maybe there other location @ c:\users\bout0_000\appdata\local not need admin @ ? maybe c:\users\bout0_000\appdata\local\temp ?

this complete exception error:

there things wrong in code, give modified version try:

public static void createdirectories()     {          outputfiles = path.combine(environment.getfolderpath(environment.specialfolder.localapplicationdata), "outputfiles");         if (directory.exists(outputfiles)) directory.delete(outputfiles, true);                     outputtext = outputfiles + "\\outputtext";                     directory.createdirectory(outputtext);          outputphotos = outputfiles + "\\outputphotos";         directory.createdirectory(outputphotos);          temptxt = outputfiles + "\\txtfiles";         directory.createdirectory(temptxt);          tempphotos = environment.getfolderpath(environment.specialfolder.localapplicationdata) + "\\photosfiles";         if (directory.exists(tempphotos)) directory.delete(tempphotos, true);         directory.createdirectory(tempphotos);                      photofilesdir = outputphotos + "\\" + "photosfiles";                     directory.createdirectory(photofilesdir);          photofilesdir1 = outputphotos + "\\" + "photosfiles1";         directory.createdirectory(photofilesdir1);          photofilesdir2 = outputphotos + "\\" + "photosfiles2";         directory.createdirectory(photofilesdir2);          photofilesdir3 = outputphotos + "\\" + "photosfiles3";         directory.createdirectory(photofilesdir3);     } 

some notes:

• it looks want delete old outputfiles folder before creating new one. deleting directory.delete(path,true) delete subdirectories , files. sub-folders (outputphotos, outputtext,...) don't exist after delete outputfiles folder , create new one. means, don't have check if sub-folders exist or not, create new ones. same logic applied outputphotos folder.
• you don't have create parent directory first before creating sub directory. directory.createdirectory(path) create parent directories needed before creating sub-directory (the last in path).
