AssetFile.Name max length is wrong

[chamelGenetec]

In the online documentation, it says the max length is 260 but I get an error saying the max length is 248.
Online doc : https://docs.microsoft.com/en-us/azure/media-services/media-services-dotnet-upload-files

Call : IAssetFile assetFile = await asset.AssetFiles.CreateAsync(resource.Name, CancellationToken.None);

Exception : "An error occurred while processing this request."

InnerException : "<m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata\"><m:code /><m:message xml:lang="en-US">AssetFile.Name length cannot exceed 248 characters</m:message></m:error>"

It turns out the max length is indeed 260 but it's not the 'file name' that's 260 but the full path + filename
Ex : C:\user\filename.jpg

I think the online documention needs to make this clear.
