HP50G File Manager Issue with SD card

[John Colvin]

Let me be clear. The same SD card was tried in both the 50G and the 49G+. The write protect was disabled on the SD card so I could purge files in the SD card root directory on both devices. However, when I attempted to purge a file in any sub-directory on the SD card, the purge failed on the 50G but succeeded on the 49G+. Both calculators have the same firmware revision.
