How do I transfer my database to another computer?

TntMPD's user guide has a great reference on this:
  How to copy a TntMPD database to a new location

What follows is additional information and ideas:

If you know how to copy a file to another computer, you can easily transfer your TntMPD database to another computer.  It's as easy as 1, 2, 3!

1.  First of all, make sure that TntMPD is installed on the target computer.  It's best to install the latest version from the TntMPD website.

2.  Copy your TntMPD database file (it's a file that ends with .mpddb) to your other computer.  (Where is my database file?)  Here are a few ideas of how you can do this:

  • Use a service like Dropbox (www.dropbox.com).  By the way, here's more info on how you might continue to use TntMPD with a service like Dropbox.

  • Email the file (as an attachment) to yourself.  (Check with your ISP on size limits of your email.)

  • Copy the file onto a floppy disk (If the file is too large for a single disk, you can use WinZip to span the file across multiple floppies.)

  • Copy the file onto a Zip Drive, Jazz drive, CD-ROM, USB Drive, etc.

  • Copy the file onto a memory stick, compact flash memory card, etc.

  • Copy the file onto an external hard drive or a network drive.

  • Copy the file directly to another computer by establishing a peer-to-peer network two computers using Ethernet, USB or Parallel ports.

3.  Once you've copied your database file onto the other computer, move it to a folder where you keep your normal documents (such as "My Documents").  Then just double-click on it, and it will open up in TntMPD!  (HINT:  If you copied the file from a CD-ROM, be sure to right-click on the file, click on "Properties" and turn off "Read Only".)

Hi Troy. Mty Mac does not read tntMPD.exe.I am not sure what to do...

On your Mac, you should install "TntMPD for the Mac".  Then you'll have a "TntMPD.app" instead of a "TntMPD.exe".

Hi Ron,  This article is not about exporting and importing a database.  It's about actually moving or copying it.  This means that EVERYTHING transfers.  --Troy

I saved my data base in 2 locations and then installed TNTMPD on the new computer and then tried to open the date base  this is message I get

An error ocurred trying to auto-compact the database...

Operation must use an updateable query

SQL = UPDATE Property SET PropValue = '40578', LastEdit = NOW() WHERE PropName = 'LastCompactDate'.

I have not bee able to open the data base.  any ideas or help?

It sounds like you copied the file to a read-only folder.  Or the "Read-Only" attribute was set on the file.  This often happens when you put the file on a CD-ROM.  Make sure the file is in a folder that you have permissions to change.  Also make the read-only attribute on the file is not set (right-click on the file and choose Properties).

I can't find the mpddb file on my Mac! Is there another extension I should find it by?

By: Troy Wolbrink Posted on 12 Aug 2011 2:49 PM

OSUfan, you should probably report this error to the forums, along with all the error details (click the "Details" button when you get this error.

I have downloaded TNTMPD onto my new computer. I have also copied my most recent database from my old computer and tried to open it in the new. When I try to open my database on my new computer it says "You do not have write permissions to the directory:

 D:."  What should I do?

By: Troy Wolbrink Posted on 22 Feb 2012 10:01 AM

Copy your database file to your "My Documents" folder.  You should have write permissions there.

It worked perfectly!!!! Thank you so much!

Thanks for the tips. I had trouble at first, but after reading some of the other comments, got everything transferred.

OSUfan, sounds like the database is read-only, or some operating system file-level security doesn't allow you to write to the database.  You might try making a copy of the database within the same folder and then try opening the copy.  (Sometimes the "copy" file operation resets the security permissions on the file.)

Anything special for transferring the whole database from a Mac to a PC? Thanks

By: Troy Wolbrink Posted on 7 Aug 2013 2:00 PM

Not really.  Just copy if over and it should open with TntMPD on your PC.
