The upload restrictions.

## Remarks
 
**Note** 
All limitations specified here are checked client-side, so you should not interpret them as a reliable protection. A potentially malicious user can bypass all these limitations (by emulating ActiveX/Java Uploader). That is why it is highly recommended to implement server-side verification of uploaded files in addition to [restrictions](https://www.aurigma.com/docs/us8/JA_T_J_$au_restrictions.htm.md) properties.
 
In other words, all limitation features discussed in this topic should be used solely for the convenience of the user. They should not be interpreted as a serious protection measure from malicious users.
