JPEG file taking Vary long file for opening

[GoogleCodeExporter]

What steps will reproduce the problem?
1. When we mount any folder which contains JPEG file.
2. Now, we open this shared folder from Mounted Drive.
3. Then we open any jpeg file. it is taking more then 20-25 seconds for opening 
this file. Why ?

What is the expected output? What do you see instead?
JPEG file should take only 4-5 second for Opening.
But it is taking more then 20-25 second for opening this file.

What version of the product are you using? On what operating system?
Dokan version - 0.6.0
Operating System : Window - 7

Please provide any additional information below.
I have seen in Dokan library. when we double click on JPEG File for opening 
then dokan library calls DokanCreateFile Function for lots of .exe file like - 
Winword.exe,Powerpnt.exe,Excel.exe, Visio.exe , winproj.exe etc.
So, I want to know the reason. why dokan library calls DokanCreateFile Function 
for .exe file because it takes some time for calling it.
