# Export to *.gps control file does not load/display properly

<span style="font-size: 16px;">When the .gps file is loaded into the display, the map is in the wrong place, part of it is missing, and/or the scale is wrong. For example, note the linework to surface mismatch on the right.</span>

</span>

<span dir="ltr" style="font-size: 16px;">**Cause:**</span>

<span style="font-size: 16px;">Trimble FMX and TMX displays can only display a certain size file. \*.gps files larger than 1MB or with too many pixels will not load correctly in FMX displays due to memory limitations.</span>

<span style="font-size: 16px;">Export again with a smaller file size. This can be done during export by simplifying to a larger pixel size. When selecting FMX, the limitations are more clearly shown, and you can resize to a larger pixel size in the export dialog:</span>

<span style="font-size: 16px;">You can also export a smaller size without increasing pixel size if you split the field into subsections. It may help to still have some overlap.</span>
