Clear caching

[dvdknaap]

Hi,

I'm using your package to read excel files but somehow the files are cached when you are using the same name for files.
I've got an program to read a excel file by pressing a button but it only show the results of the first result.

So when i read the excel file do some changes to the excel file read the file again then i get the same results as the first read.

How can i clear the cache so it will always get fresh results ?

Thanks,
Danny
