I'm very interested in the Ajax File Storage example but the project won't open. I think your solution file is referencing things on your computer or something:
Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "C:\...\AdvancedCS20\", "..\..\..\..\..\..\AjaxUploader\Code\CuteWebUI.AjaxUploader\Samples\AdvancedCS20\", "{BFDEA4C1-578C-4398-A6A4-6F69858C8B5C}"
ProjectSection(WebsiteProperties) = preProject
Debug.AspNetCompiler.VirtualPath = "/AdvancedCS20"
Debug.AspNetCompiler.PhysicalPath = "..\..\..\..\..\..\AjaxUploader\Code\CuteWebUI.AjaxUploader\Samples\AdvancedCS20\"
Debug.AspNetCompiler.TargetPath = "PrecompiledWeb\AdvancedCS20\"
Debug.AspNetCompiler.Updateable = "true"
Debug.AspNetCompiler.ForceOverwrite = "true"
Debug.AspNetCompiler.FixedNames = "false"
Debug.AspNetCompiler.Debug = "True"
Release.AspNetCompiler.VirtualPath = "/AdvancedCS20"
Release.AspNetCompiler.PhysicalPath = "..\..\..\..\..\..\AjaxUploader\Code\CuteWebUI.AjaxUploader\Samples\AdvancedCS20\"
Release.AspNetCompiler.TargetPath = "PrecompiledWeb\AdvancedCS20\"
Release.AspNetCompiler.Updateable = "true"
Release.AspNetCompiler.ForceOverwrite = "true"
Release.AspNetCompiler.FixedNames = "false"
Release.AspNetCompiler.Debug = "False"
VWDPort = "53928"
EndProjectSection
EndProject
