WebClient Service File Size and File Attribute limits

This keeps on coming back but when opening a SharePoint location with WebDav running the WebClient Service.

There are 2 parameters that we became very aware of recently else files won't open or directories with large amount of files won't show in Windows Explorer view.

The attribute FileAttributesLimitInBytes under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WebClient\Parameters.  The controls the limit to the file attributes size that is returned.  It is set to 5 meg by default, I think.The settings are in bytes thats why its so big in size.

5 meg will probably be enough for say 7000-8000 file attributes.

Increase the size if more files are returned by a directory.  Else a timeout like message gets shown by Windows Explorer.

If there are actual files that needs to be read from a SharePoint location that exceeds 50 meg.  The FileSizeLimitInBytes attribute needs to be adjusted under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WebClient\Parameters.  It is set to around 50 meg by default.  Set it to higher if required to read larger files.

Restart the WebClient service for it to take effect.
