Hi, could someone please advice what would be the fastest way to extract channel group properties of around 400.000 files? I currently use DataFileLoadRed with only the channel group I am interested in and the channels stripped down to a single value by setting the no. of intervals to 1 and SectionBegin/End to 1/2. Any improvement suggestions? Phex

An alternative would be to open all files with the folowing code. Option Explicit dim groupindex : groupIndex = 1 ' you can also use a groupname instead dim groupProperty : groupProperty = "description" ' include this in a loop over all your files dim filePath : filePath = "C:\temp\example.tdm" dim store : set store = navigator.ConnectDataStoreByParameter("TDM", "<filename readonly=""yes"">"& replace(filePath, "&", "&amp;") & "</filename>") dim propVal : propVal = store.RootElements(1).Children(groupindex).Properties(groupProperty).Value MsgBox propVal The files are opened and your properties are extracted. Potentailly the datafinder approach should be faster but if you do not get it work this may be a way out.

Awesome! I can connect my 400.000 files in less than 20min. Considering the amount of time that DataFinder needs to index the 400.000 files I would take this as the fastest solution. Thank you so much!
