-=====The Flash Disk=====
+=====Onboard Storage=====
-There is ~2MB 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.  Twiddler.cfg file is stored on the root of this drive.
+There is a small amount of storage available on the Twiddler. \\
+It is used to store your **Config** (4 x *.cfg), **Re-Chorded log** (4 x *.log) and **Firmware upgrade** (1 x TWIDDLER.BIN) files. All other file types will not be stored on the Twiddler. \\
+Storage is only accessible when the Twiddler is connected to your computer via USB.  \\
+It should mount as a FAT formatted Removable Hard Drive on your host device.  \\
-====File Limitation====
+====File Considerations====
+\\
+===Twiddler Config Files===
+There are four (4)  Twiddler Config files stored on the Twiddler 4
+^File Name^Purpose^
+|0.cfg| Reserved - Default Config|
+|1.cfg| 1st custom config slot|
+|2.cfg| 2nd custom config slot|
+|3.cfg| 3rd custom config slot|
+\\
+**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.
-You can store multiple twiddler.cfg files on the flash disk but they need to be located in a sub-directory. FAT has a very small limit to the number of files that can be located in the root of the drive.  Adding more than the limit to the root will display a write error.
+===Twiddler Re-Chorded Log Files===
-====Formatting the Flash Disk====
+There are four (4)  [[t4_datalogger|Twiddler Re-Chorded]] log files stored on the Twiddler 4
+^File Name^Purpose^
+|0.log| 1st custom config slot|
+|1.log| 2nd custom config slot|
+|2.log| 3rd custom config slot|
+|3.log| 4th custom config slot|
+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]].
