Error while displaying file " C:Temp Filename.Ext cannot be created"

Question

Dear Friends
Some users face problem while display the file. They get message " C:\Temp\ Filename.Ext cannot be created ". I checked Details. I got explaination as follows.
Caution! You are not authorized to work with temporary storage
Message no. ED204
Diagnosis
You do not have authorization to read or write from or to the temporary storage.
The system uses the temporary storage when you display or change programs using the ABAP Editor.
The system checks to see whether there is a temporary version of the program.
If there is, a dialog box appears in which you must choose whether to use the temporary version or the database version.
The system fills the temporary storage when the editor crashes or you save a temporary version of the program.
System Response
You probably do not have the authorization object S_DATASET.
Procedure
Ask your system administrator to assign you the relevant authorization.*
Actually this  problem never occurs frequently. User access the files very frequently creating around 200 Mb to 400 Mb in C:\Temp Folder per day per user. I observerd as per message that User is not have Access right to C drive. Once I get access from IT for that user he is able to display file. But before giving right he is able to display file. But suddenly he is not able to display. I am not getting exact reason why this problem occurs. Some users temp folder size is upto 700 Mb with no acces right to C Drive still he is able to see the image.
In DC20 I have kept C:\Temp as path for temp folder.
I have checked the links  also
Request you to provide me
What is exact reason of the error?
Is the solution to problem is giving access rights to the user?
Do I have to give authorization object S_DATASET to a user?

Dear Amaresh
Thanks for your reply and solution.
So you mean to say thats this Authorization object  has to be provided to user?
But my question is how the user was able to see the file even when this Authorization Object was not assigned.
He was able to display all file. But for particular DIR he is not able to display.
I have checked this thread
