See manual for details about installation and configuration of PowUpload.
All examples tested in 0-10 years old releases of most popular browsers (Internet Explorer, Mozilla/FireFox, Opera, Netscape).

PowUpload has one of 2 limitations types:
1. If PowUpload was installed by the automatic installer there is 30 days evalutation period without any functional limitations. After this period it uses limitation (2).
2. If just PowUpload assembly was downloaded and included to project it have not time limit, but (a) Handles only uploads at "localhost" server; OR (b) Uploads to any server files less than 25 MB each.
We hope that these are enough conditions to test PowUpload. To discard these limitations please buy the corresponding full license.
