I have an existing SQL database with an accompanying VB(2015) application. Presently the two are on different drives. I would like to put both on a thumb drive so I can access it on any computer.

There are 2 obvious problems;

1 How do I transfer the data file to the thumb drive and still have the application find it?
2 When moving the thumb drive from one computer to another the drive designation will change, how do I tell the application to handle this?

What I have tried:

I have tried to do the above, but when I put the drive in a different computer I get a file not found error.

I assume you are using SQL Server, unfortunately SQL Server is notoriously difficult to deploy in such a way.
So if possible think of alternatives like storing your data in XML format, or using a more suitable database like SQLite or PostgreSQL (which has a portable version), PostgreSQL Portable download | SourceForge.net[^]
Here is a small VB.NET example: PostgreSQL and VB.NET-VBForums[^]
