problem about partition

[h ch]

for instance, i have a table with myisam engine,with unpartition table i get 2 file
mytable.MYI and mytable.MYD, but when i split the table into 2 partitions,i get 4 file ,mytable#P#p0.MYI mytable#P#p1.MYI mytable#P#p0.MYD mytable#P#p1.MYD ,that's means when i use mytable,i need 2 extra file handles ,so when i have a table with 100 partitions ,when i open the table ,the file handles number is big,that a big problem!! anyone can explain this??
