organizing videos in separate folders

Is this possible? I have a bunch of different types of show episodes and would like to organize them by putting each category into a folder.
I've tried creating directories and just placing the videos in but it simply just doesn't show the directory or the video.
I'm using v3.4 oe-a and place videos in mp_root\100mnv01

Just put them in the VIDEO folder on the root of your memory stick.

Just sift through that real quick it'll tell you how to do it.

Get some videos on your PSP. On 2.71 firmware, this is very easy. You just create a VIDEO folder (video should be in all caps) on your PSP Memory stick (USB cable required), usually it's Drive E:\. Create the folder right on the memory stick and NOT inside of the PSP folder (that's what old firmwares make you do). So, This is what you should see when you click on the VIDEO folder in your status bar: e:\VIDEO . E:\ stands for whatever drive your psp is in. Inside the VIDEO folder, paste your videos. Videos can be in MP4 or AVI format. Filenames do not matter. You can also have a subfolder inside of the VIDEO folder. If you make a folder inside of a subfolder, PSP will ignore it. If you are using firmware that's bellow 3.00, you should create a folder MP_ROOT on your memory stick (again, not in PSP folder, just on memory stick). Inside of MP_ROOT Folder, you will make a 100ANV01 folder. Inside of 100ANV01 folder, you will paste your videos. Videos should be in MP4 format. Here, the filename does matter. You will rename your mp4 file to M4V*****.MP4 where each * stands for a digit.
