StreamWriter creation error

[Matt]

Hi There,
Our application creates a file using StreamWriter. The application
creates the file in a unique path and deletes the folder after the
file is transferred to a designated location (a network drive or a
another folder). The problem that we are facing is that some times
(usually after more than 12000 to 18000 such file/folder operations
i.e., create folder, create file, transfer, delete) the StreamWriter
creation fails with "Could not find a part of the path" error. Here's
my flight log for the error. As becomes obvious from the log, the File
creation failed with the path error even after the directory was
created successfully. So my doubt is, does the .Net framework (or
Windows) cache folder creation? I read something akin to this here
