Only some files upload?

[James_McMurray2]

I'm using Apache Server on Windows 98 with php 4. I have a page that allows the uploading of files, but it only works if those files are already somewhere in apache's htdocs folder. For instance, if test.html is on the desktop, it returns 0 for the filesize and does not set the filttype, thus failing at the copy step. However, if the file is in the base htdocs/ directory, it uploads just fine.

Is there something I'm missing here?

Thanks

A bit more information: I do have file uploads enabled in php.ini.
