Subject: [Qt-interest] Unable to remove QTemproray file: "Access is denied" on windows xp



Hello
 
[Windows XP SP2, Visual Studio 2005 with SP1, Qt 4.6.1]
 
I'm trying to create a program that caches some of it's data to disk, to save memory.
 
QTemporaryFile seemed to be just the thing i'd need.
 
However, when it's deleted, the file isn't removed. (auto remove option is turned on by default)
 
Debugging with visual studio revealed that an error occurs while attempting to delete the file, an error string is also present and it contains "Access is denied".
 
I have tried giving various open-modes and permissions, but the file still persists.
 
I even tried to use QFile to access the files, but even there remove failed.
 
Deleting the file works, if i delete it from
-Windows file explorer
-QFile::remove(<path to file>);
 
The second option only works if i don't attempt to do it from the same process. The time it worked the old process had already ended.

 

Any ideas on what I might be missing here?
