I have a text file that is 2.7 GB in size and contains about 4 million rows of data. This cannot be opened in txt format and I need to manipulate the data. I am attempting to upload this data into Access in order to make alterations and run queries. When trying to import, I get a response that there is no data in the file. I need to be able to import but I don't know what else to do.
 

Excel Facts

Excel Can Read to You
Customize Quick Access Toolbar. From All Commands, add Speak Cells or Speak Cells on Enter to QAT. Select cells. Press Speak Cells.
Unfortunately you'll probably have to read this one line at a time using

Code:
Dim strPath As String
Dim strInput As String
Dim varTemp As Variant
Dim rst As DAO.Recordset
 
strPath = "C:\YourFolder\YourFileName.txt"
Set rst = CurrentDb.OpenRecordset("YourTableNameHere")
 
Open strPath For Input As #1
Do Until EOF(1)
LineInput #1, strInput
 
varTemp = Split(strInput, ",")
 
With rst
   .AddNew
   !Fields(0) = varTemp(0)
   !Fields(1) = varTemp(1)
   !Fields(2) = varTemp(2)
   !Fields(3) = varTemp(3)
   !Fields(4) = varTemp(4)
   !Fields(5) = varTemp(5)
  .Update
Loop
rst.Close
Close #1
Set rst = Nothing

Something like that. Here's more of a reference on this.

How exactly are you trying to import the file?

When do you get the message?

If you are using File>Get external data... do you get as far as the Text Import Wizard?

Another potential issue; the Access file size limit is 2 Gb. If you try to exceed that you will have problems.
