The file upload limit for our shared hosting environment is 100Mb.

If you are on a deployed server there is an option to configure this limit within the web.config.

For reference these are the standard values that need altered. These are set based on Microsoft’s own recommendations with respect to machine capacities and paging sizes. Microsoft have stated that exceeding these limits can reduce machine stability.

When connectivity is poor time can be more of a limiting factor on upload as the upload can time out prior to the file being uploaded. The upload process cannot anticipate file sizes so unfortunately the system will only ‘know’ a file is too big once it has been uploaded and the limit has been exceeded.
