<p>I want to compare two ms-access .mdb files to check that the data they contain is same in both.</p>

<p>How can I do this?</p>

If you want to know if the files are identical then
```
```
fc file1.mdb file2.mdb
```
```
on a DOS command line.
If the files aren't identical but you suspect they contain the same tables and records then the easiest way would be quickly write a small utility that opens both databases and cycles through the tables of both performing a heterogeneous query to extract the Diff between the two files.
There are some tools out there which will do this for you, but they all appear to be shareware.
