Hi,
I can upload a file with 160+chars .
The problem is that, when uploader save the file to the temp directory,
the path is :
x:\folder1\tempdir1\xxxxxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx.filename.ext.resx
the folder path, the guid, the '.resx' will spent at least 42 or more chars.
and windows do now allow save it .
That is the condition of the 'default provider'
You can write custom provider to save the temp file.
Please check this thread :
I have tested 254 chars.
Regards,
Terry
