I went back to the SQL query and did the convert as it is the simplest solution in my case. Johnny Bones Johnny Bones 8, 6 6 gold badges 40 40 silver badges bronze badges. Jon Miller Jon Miller 51 1 1 silver badge 3 3 bronze badges.

What i would do is develop a sub to read the whole file and maintain a line count. Import each one into its own db. Link all the tables in one main db. Local time Today, Joined Feb 6, Messages 4. I cannot access the source data or request another data dump.
I am running XP. The 1 of the 12 files that is under 2GB imported fine so I don't think its anything to do with the file name or data format. I could easily trim some of the rows and columns once I get it into Access and shrink and aggregate the useful data, but I need to get it into Access first.
What is my problem? I don't understand what a "sub" is. Local time Today, Joined Jul 2, Messages 13, I believe the previous posters were suggesting you link to the files, not import them. DCrake Remembered. Local time Today, Joined Jun 8, Messages 8, I have this VB project that splits files into smaller chunks and rejoins them if you want it to.
I have quickly converted it to Access. RuralGuy : I am aware of the difference between Importing and Linking tables. Do you recognize the error?
However, the contents and structure of a linked table in Access are read-only. When you open a text file in Access, Access creates a blank database and automatically starts the Link Text Wizard.
Note that you can link to only one text file a time during a link operation. To link to multiple text files, repeat the link operation for each file. Ensure that the file consistently follows one of the formats. If the file is delimited, identify the delimiting character. If the file has fixed-width fields, ensure that each field is the same width in every record. Text qualifiers are not required, but they are essential if:.
For example, if a comma is used as the field delimiter, and New York, Chicago is a valid field value, you must enclose the value within a pair of qualifiers, such as: "New York, Chicago". You want Access to treat non-text values, such as and , as text values and store them in a text field. During the linking operation, you can specify whether the file uses a qualifier and, if so, you specify the character that acts as the qualifier. Ensure that the same text qualifier is used throughout the file and that only text values are enclosed within a pair of qualifiers.
If there are blank fields, try to add the missing data in the source file. To avoid errors during linking, ensure that each source field contains the same type of data in every line. We highly recommend that you ensure that the first 25 source rows do not mix values of different data types in any of the fields.
You should also ensure that any non-text values that you want to be treated as text values are enclosed in single or double quotation marks. If the source file contains mixed values in the rows following the 25th row, the import operation might display error values or convert them incorrectly. For troubleshooting information, see the section Troubleshoot Num! For delimited text files, if the file does not include the names of the fields, it is a good practice to place them in the first row.
During the linking operation, you can specify that Access treat the values in the first row as field names. However, when you import fixed-width text files, there is no option for treating the values in the first row as field names. Open the database in which you want to create the link. Ensure that the database is not read-only and that you have the necessary permissions to make changes to the database.
In the Get External Data - Text File dialog box, specify the name of the text file that contains the data to which you want to link in the File name box. Select Link to the data source by creating a linked table and then click OK.
Access scans the contents of the file and suggests how the file is organized. If the file uses a delimiting character to separate the fields, you should ensure that the Delimited option is selected.
The next page of the wizard that is displayed depends on whether you selected the delimited option or the fixed-width option. Delimited files Select or specify the character that delimits the field values. If the file users a text qualifier, in the Text Qualifier box, select either " or '.
Fixed-width files The wizard shows the contents of the file. On the next page of the wizard, Access displays the field properties. Review and change, if you want, the name and data type of the destination fields. If there are different types of values, such as text and numeric values, in the first 25 rows of a column, the wizard suggests a data type that is compatible with all or most of the values in the column.
In most cases, that is the text data type. Although you can choose a different data type, remember that values that are not compatible with the chosen data type will either result in error values or get converted incorrectly. For more information, see the next section, Troubleshoot Num! The Advanced button in the Import Text Wizard allows you to create or open a link specification in the format used by earlier versions of Access. Access does not provide a way to save a link specification, unlike import and export operations, so if you want to save the details of a link specification, click the Advanced button, set the options you want, and then click Save As.
On the final page of the wizard, specify a name for the linked table and click Finish. If a table with that name already exists, Access asks if you want to overwrite the existing table. Click Yes if you want to overwrite, or No to specify a different table name. Access attempts to create the linked table. If the table is successfully created, Access displays the message Finished linking table Open the linked table and review the fields and data to make sure you see the correct data in all the fields.
Even if you see the message Finished linking table , you should still open the table in Datasheet view to verify that all the rows and columns show the correct data. If you see errors or incorrect data anywhere in the table, take corrective action as described in the following table and try linking again. Remember that you will not be able to add the values directly to the linked table, because the table is read-only.
When you link data, Access does not enable support for multiple values in a field. The list of values is treated as a single value and placed in a text field, separated by semicolons.
If increasing the width doesn't resolve the issue, the cause might be that the data type of a numeric field is set to Long Integer, when it should have been set to Double. When you open the table in Datasheet view, you might see that some fields contain Num!
Do the following to minimize or eliminate any instances of null values in the source file:. During the linking operation, select the appropriate data type for each field. If the data type is incorrect, the entire column might contain only Num!
The following table lists cases where you will still see the Num! If the values that are missing are of type Replace all text values with values that match the data type of the destination field and then try linking again.
