Note
• Up to 1000 files and directories can be displayed in the file list. If there are more than a total
of 1000 files and directories in a given directory, the file list for that directory will only display
1000 files and directories. There is no way to set which files and directories are displayed.
• If there are a large number of files on a single directory, the amount of time that it takes to
write to and read files becomes longer. If this happens, start saving files to a directory with
less files, or move the files in the save destination to a different directory.
• If you change file name extensions through a PC or some other means, the WT500 will not
be able to load the files.
• Files without archive attributes are not displayed in the File List window. Do not clear the
archive attributes of files on your PC that were saved using the WT500.
• File paths can be displayed using up to 41 characters. If a path exceeds 41 characters, an
ellipsis appears at the end of the character string.
• File names are not case-sensitive. Comments are case-sensitive. The following file names
cannot be used due to MS-DOS limitations:
AUX, CON, PRN, NUL, CLOCK, COM1 to COM9, and LPT1 to LPT9
