ex.Here is a dir picture have over 10000up jpg
Step.1 When i restart tc and press space key on this dir,it still take a few times.
but if i use below operation
Step.2.1 Restart tc and press space key on another small dir and get the space,then i press on the dir picture,it will show size almost immediately.
or
Step.2.2 Restart tc and press space key on dir picture,when tc is still caculate space i press esc to cancel this operation and press space key again,
and now i get the dir size immediately
It seems the first time press space key to caculate space tc is not get index from everything,
but after caculate one time(the step 2.1or 2.2),all the operation will get everything's info correctly.
I don't know it's a bug or not that tc seems doesn't call everything on first time.
Thx for your watching

PS.by the way,will the operation CTRL+L Calculate occupied space (of the selected files)
can also use everything to make it fast?
