# Loading your Design

Once your WIF file is saved to the Micro-SD card, with the power off, insert the Micro-SD card into the System Unit. The metal contacts on the card need to face towards the back when inserting the card.  

It is important that the metal contacts face to the back (away from the screen) when inserting the card.  

Power the System Unit on, and choose Project Setup.

Next select Load WIF.   

Select the file name by placing your finger or pointer directly on the file name.  Once selected, a green "Load" button will appear.  Press the green Load button.

Green arrows on the right are available to scroll up and down if more files are on the card than will fit on the screen.

When your file is being loaded, you will see a progress indicator for the threading, treadling and color loading. Once finished loading, the main menu shows once again, ready for you to select Weave or any other option.

By default, TempoTreadle sets Auto-Load to "On", meaning that each time you power up the TempoTreadle system unit, it will automatically load the last project that was used.  This saves time from finding and selecting the current project.  When ready to change to a new project, simply do a File | Load and then the the new project will become the default.  The Auto-Load setting is on the System Settings menu.

Loading an Updated Version of a Project - Please Read

When you need to update the WIF file on a project that has been previously loaded on your SD card, it's recommended that you load it with a slightly different name.  If you simply replace the WIF file on the SD card, there is a change that the changes you made may not be reflected properly as TempoTreadle builds some special files to optimize the performance using the name of the draft.
{% endhint %}

{% hint style="info" %}
Loading a Draft that will have the same Treadle Mappings

When loading a new draft, perhaps an updated version of a project that's underway, there is a setting at the bottom of the Load WIF screen that allows you to "Copy Treadle Settings".   Change this value to "Y" to use the treadle settings (mappings, state, alerts) from the currently loaded WIF to the file being loaded.
