+=====Onboard Storage=====
-There is 175k of non-volatile file storage available on the Twiddler.  It is accessible only when the Twiddler is connected to your computer via USB.  It should mount as a FAT formatted Removable Hard Drive.  Both the Twiddler Config (4 x *.cfg) and Re-Chorded log (4 x *.log) files are stored on the root of this drive.

+**NOTE:** Once a config file has been copied to the Twiddler, the USB cable needs to be unplugged in order to confirm and commit that file to storage.
-When you create custom configs, copy them to the Twiddler.  Do not overwrite 0.cfg as it is reserved for the factory default config and will be overwritten by the Twiddler.
+===Twiddler Re-Chorded Log Files===
+There are four (4)  [[t4_datalogger|Twiddler Re-Chorded]] log files stored on the Twiddler 4

-====Formatting the Flash Disk====
+All log files can be selected and written to when in Re-Chorded mode.  Just keep in mind that there is a hard 64K limit on the size of each log file.
-There are times that you may wish to reformat the Twiddler's flash disk.  This procedure is safe and will not affect the firmware on the Twiddler.  Just remember to backup the data on the drive as formatting it will wipe it clean.
-The drive must be [[wp>File_Allocation_Table#FAT12|FAT Formatted]].
