Opening a directory that contains a large number of files causes a crash
System and version used: version 5.1.0, running on a New 3DS XL
How to reproduce: On the SD card, create a new directory, then fill it with a very large number of files (in my case, the 2206 images of the https://www.gametdb.com/ boxart download). When that directory is navigated to in 3DShell, the program will crash, necessitating a system restart. As 3DShell remembers the last visited directory, it will subsequently crash every time it is opened, until that directory is emptied, or at least the number of files in it reduced.
Can confirm I'm having this issue too with around 300 folders.
I'm looking into re-writing 3DShell to resolve some of these outstanding issues but don't have any ETAs at the moment.
