why JPEG file takes more time for opening

[GoogleCodeExporter]

What steps will reproduce the problem?
1. when we mount any shared folder which contains JPEG File.
2. Then we will open JPEG file from Mount point.
3. Then it is taking more time. why ?

What is the expected output? What do you see instead?
JPEG File should take only less then 4 - 5 second for opening.but
Jpeg file is taking almost 20-25 seconds for opening.

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

Please provide any additional information below.
i have seen in Dokan library. when we double click on jpeg file then dokan 
calls DokanCreateFile function for lots of .exe file , which is not present in 
Mounted drive. so why does dokan call this function for .exe file like - 
Winword.exe,Powerpnt.exe, Excel.exe,Visio.exe, winproj.exe etc. 
so I want to know the reason for calling this function for 
Winword.exe,Powerpnt.exe, Excel.exe,Visio.exe, winproj.exe etc.
