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
