SDHC cards (2 GB to 32 GB)
Supplied or purchased SDHC cards are formatted in the
FAT32
file format. This format
is
supported
by Performance Box Touch.
SDXC cards (64 GB and above)
Purchased SDXC cards will be formatted in
exFAT
or
NTFS
file formats; these formats
are not supported
by
Performance Box Touch. Please reformat as per the instructions below.
SD Card Reformatting
• FAT32 reformatting for media with sizes up to 32 GB can be done directly in Windows by right-clicking on the
media and selecting '
Format
'.
• If you would like to format media with sizes above 32 GB into a FAT32 file system, you cannot do it directly in
Windows as it is not the standard formatting for the file. However, there are many third-party software programs
you can use to reformat media so that they will work correctly with our products - we recommend
as
a free option from the SD card organisation.
