Note:
If you use up all the available memory while recording, you will hear the error
sound and recording cannot continue.
Each recording is stored in a separate file located in My Handheld PC\My
Documents\Voice Recorder. If desired, you can change the default location from
the Options menu of Voice Recorder.
Files are named using the prefix word "Voice Rec", plus the current date and a
3-digit sequential number. Dates take the format YY-MM-DD.
Example: a voice recording created on October 1, 1997 would be given the
name
"Voice_Rec_97-10-01_001.wav".
The sequential number applies to each folder, so if you change the default folder
then the sequential number for the new folder will start from 001. If a file with the
same name already exists, then the number will be skipped.
