我有超过一千个名为LOGS_A1, LOGS_A2, LOGS_A3 , ..., LOGS_A16281` 的文件,我想按该顺序列出这些文件
cwd = pwd()
ParentDir = joinpath(cwd,"LOGS_A")
dirs = readdir(ParentDir, join=true, sort=true)

但是,它按字母顺序对条目进行排序:
LOGS_A999
LOGS_A9990
LOGS_A9991
LOGS_A9992
LOGS_A9993
LOGS_A9994
LOGS_A9995
LOGS_A9996
LOGS_A9997
LOGS_A9998
LOGS_A9999
