Got it working but my next problem is the using of GetFullPathName.
Example:

I have found a folder on drive C:\ (maybe my_files) the full name should be
C:\my_files but when i use the GetFullPathName i got C:\Dev-Cpp\my_files\
because the test prog. is located in the Dev-Cpp dir.
The problem is it doesn't exist a C:\Dev-Cpp\my_files\ folder, so i can't work
with it.

I hope you can understand my problem

@TripleX maybe this is usefull to write a Virus ^^
