Are the 100 file names fixed and what about location of such?
If these are fixed then just create a table to store the location string, e.g. C:\Down\file001.txt. Just enter a record for each of the 100 files.
Then you need to write some code to loop through the table and import each of these files. Since importing will overwrite the contents of the table that were there previously you will in effect need to import the files into one table and then do an append to your main table.
Create a function with the following code, calling it should run through the imports. Change the table names to whatever suits
ImportList - list of import files locations
ImportTemp - temporary table to import files to
ImportMain - the main table where all imported details append to
Dim db As DAO.Database
Dim rstImpLst As DAO.Recordset
Dim strSQL As String
Set db = CurrentDb
strSQL = "SELECT ImportList.* FROM ImportList;"
Set rstImpLst = db.OpenRecordset(strSQL)
rstImpLst.MoveFirst
Do While Not rstImpLst.EOF
strImpFile = rstImpLst.Location
DoCmd.TransferText acImportDelim, , "ImportTemp", strImpFile
strSQL = "INSERT INTO ImportMain SELECT ImportTemp.* FROM ImportTemp;"
db.Execute "strSQL"
rstImpLst.MoveNext
Loop
