Has anyone ever run across this?<BR><BR>I upload a tab delimited file to a web server, then convert the tab file to a dataset, then write the dataset to an XML. Sometimes, not always...when I try to delete the file, through and FTP program or something like that, the file cannot be deleted. This also happened locally on my machine here. The only way to stop it from happening was to restart IIS. Anyone know what could be the problem? Thanks alot. I will post code if neccessary.
