Files should only have Aa-Zz, 0-9 and -_ in them. Folders can have spaces, but this may take longer for the game to read. Files should not have spaces in them. If there are special characters in a file (dots and other punctuation, brackets of any kind, or various other non-alphanumeric characters), the game may or may not be able to read the files, and if the files are read then loading may take longer.
Several people have had troubles with files where special characters or extra punctuation was added (and yes, this turned out to be the actual problem - I remember someone had named their files something like "1.red.package" and couldn't get the files to show - removing the extra dot solved the problem). Brackets and some other characters tend to work fine, but since they may make loading longer, it's best to avoid them since they add unnecessary characters to the real filename.
SimPE should be able to read most files with special characters (extra dots being a clear exception, since anything behind the dot may be considered to be the file extension). I've even managed to open files with asian characters - but I have no idea if they showed ingame.
