Remarks

When the ASPxFileManager uploads a file in advanced mode (the FileManagerSettingsUpload.UseAdvancedUploadMode property is set to true), the file is sent to the server in small packets (one at a time). The packets are saved into a temporary file until upload is complete. After that, the file manager applies access rules. If the file manager denies file upload, the control deletes the file and displays an error message.

Set the EnableClientAccessRuleValidation property to true to allow access rule validation on the client side. In this case, the file manager checks a file accessibility before the control uploads it to the server side.
