Okay…. I was trying to dump a umd, and it said that there was not enough space. I have a 16gb memory stick with more than 8gbs of free memory (or at least it says i have that much free space in the xmb). Xplora said I only had 43mbs left and only about 3gbs total, so I put something bigger than 43mbs on my memory stick… there were no problems with that...
Now the information says:
Available: 3906.09 MB
Used: -938.09 MB
Total: 2968.00 MB
I'm fairly sure that you cannot use a negative amount of memory or have more available memory than the total memory, but maybe your homebrew is greater than anything else in existence and can defy all logic with ease

.
Can it not display more than that amount of mbs at a time? I really have no idea what the problem is… Is this a known issue? Is something wrong with my memory stick?
After that the umd dump worked fine…
btw I love Xplora
