GPSU Batch File Converter

Designed for GPS data processing, GPSU Batch File Converter is a straightforward and approachable program that can convert files between multiple formats in batch mode.

Extensive file type support

The app supports an extensive list of file types, such as .kml, .kmz, .kwf, .log, .map, .ov2, .pdb, .rxf, .rwf, .shp, .trl, .way, .wpt and .txt. It requires that you have GPS Utility installed.
After a fast installation procedure, you are greeted by a large window that doesn't put emphasis on look but has all options neatly organized.

Convert and merge files in bulk

It lets you indicate the source folder whose entire files you want to convert, pick the source and output file type, merge file types with other file types, and set the destination folder (same as the source or custom).
Once you have chosen a source file type, the program lists all identified files in the source destination, along with the total number of items. All or just selected files can be submitted for conversion.
Alternatively, you can process all files aside from the selected ones. This task doesn't take a long time. Worth noting is that the application automatically overwrites any existing files in the destination, so make sure it's empty.

Evaluation and conclusion

No error dialogs popped up in our tests, and the tool didn't freeze or crash. It finished bulk conversion jobs quickly while remaining light on CPU and RAM consumption, so it didn't hamper PC performance.
All in all, GPSU Batch File Converter offers a fast and effective solution to converting GPS data between various formats in batch mode, and it supports a wide range of file types for both the source and output.
