mpq program question?

[houseplant2]

I have used a couple different mpq programs but i have a problem with making a large mpq. like i am trying to make an mpq with all the creatures and blp files i currently can use on my server. when i do it comes out fine except it trys to place some of the critter folders with similar names inside one another. i cant think of an actual example but if you had a folder called felbat and one called felbatlord. all the programs i have tried (3 or 4) will place the felbatlord folder inside the felbat folder and the information inside that folder is currupt. has anyone had this problem and do you know of a program that doesnt do this? it works fine if i do it folder by folder. but to do this for the creatures folder or god forbid the world folder. it is far to time consuming. like i said. it does most fine. but a few it messes up. i could go in and put in the fixed folders but if i do like the world folder....i wouldnt be able to identify all the currupt folders. sorry if this was confusing.
