File upload class problem

[eluser]maderic_m[/eluser]
When I upload a file, the file is placed in the specified directory but also generates an empty file whose name is a MD5 string , any idea why this might happen? the application runs on an IIS, with PHP5, thanks

Already I solved, the problem was due to the write permissions of the folder, could only write but not delete, thanks anyway
