Dynamic table linking to text file

Question

Access 2013.accdb
A large quantity of text files will be arriving to the user.  They will all have the same fixed width format, but their file names will vary, and their stored location.
The data needs to be appended into Table1
I am thinking this approach: Link to a model text file Model.txt, and as part of that normal table linking I can set up the fixed width definitions for the fields.  I have already done this ok. So I have this linked table 'Model1' in the navigation
pane
When a new text file comes the user will archive it in a folder:  New1.txt
I can then get the path as a string: "C:blah blah \New1.txt" lets call this NewString
So what I am thinking is in order to Append in the new data; to first dynamically change the link table path to Model1 into the NewString and refresh the connect.
The AppendQuery is looking for Model1 so that table name must not change, and the fixed widths that were part of the Model1 initial linking must not change.
Does this sound viable - and what is the code for Model1 table relinking?  Table Def connect properties is not something I've delved into and much of the research I've found is seriously old mdb vintage
I do not think the import spec feature of 2013 allows a dynamic change in file location / name - though if I am wrong on this point please let me know.  And I think in terms of a TransferText import I would lose the fixed widths definition and
it would come in only as a single field file.  So these are the reasons I am thinking of manipulating the table path connection.
Definitely would welcome advice on this one.  TIA

Answer 1

getting a path to a file is pretty straight forward code out there for Windows Explorer file selection:
'file select
Dim strFile As String
      With Application.FileDialog(1)
           If .Show Then
               strFile = .SelectedItems(1)
           Else
               MsgBox "No file selected", vbInformation
               Exit Sub
           End If
       End With
'end file select
so strFile would be what I termed NewString in my original post;  I have found code to change links to Access tables and even excel files - but haven't found what works to a text file....the code that I've experimented with does not like the .connect
refresh......
