How to remove multiple $APPDATA
  My application saves data into application data folder for each user.

"C:\Documents and Settings\USER_A\Application Data\Company\AppName"
"C:\Documents and Settings\USER_B\Application Data\Company\AppName"
"C:\Documents and Settings\USER_C\Application Data\Company\AppName"

My own MFC based uninstaller removed these folders using CFileFind, FindNextFile, IsDirectory, GetFilePath...

Now I'm rewriting my setup program using NSIS.
I think that this $APPDATA removal feature is frequently used one in uninstallation. However I couldn't find out APIs or relevant sample. Is there any easy way to do this? or function sample?

Thanks in advance

File searching commands are available, see the Users Manual.

Hi :) !

As far as I know there is nothing available, but you could use this code, assuming that the users names are stored in a string named "users", separated by "|". For instance: "user_A|user_B|user_C"

nsh

>!include LogicLib.nsh

>${StrTok}

${UnStrFunc}

${UnStrTok}


>/*


your defines / code / etc


*/


>Function un.RemoveAppData

  Push$0 ; Token Counter

  Push$1 ; Current token (user)

  

  ; Initialises the counter

  IntFmt$0 "%d" 1              

  

 ; Get the first user

 ${UnStrTok} $1 $users | $0 1    

  

 ; Loop until there are no more users

 ${DoUntil} "$1" == ""         

   MessageBox MB_OK 'Removes "C:\\Documents and Settings\\$1\\Application Data\\Company\\AppName"'

    

   ; Removes the AppData directory for the current user

    RMDir "C:\\Documents and Settings\\$1\\Application Data\\Company\\AppName"

    

   ; Increment the token counter

    IntOp$0 $0 + 1

    

   ; Get the next token

   ${UnStrTok} $1 $users | $0 1

 ${Loop}

  

 Pop  $1

  Pop $0

FunctionEnd
