查看“IDL中的基本文件操作”的源代码

*FILE_BASENAME:去除文件的目录，扩展名等,例：
:PRINT, FILE_BASENAME('/usr/local/itt/idl/lib/dist.pro', '.pro') 
:IDL prints:
:dist 

*FILE_CHMOD
:FILE_CHMOD, 'moose.dat', '664'o 

*FILE_COPY
:FILE_COPY, 'myroutine.pro', 'myroutine.pro.backup' 

*FILE_DELETE
:FILE_DELETE, 'moose'

*FILE_DIRNAME
 temp = DIST(4) ; Ensure that DIST is compiled 
 PRINT, FILE_DIRNAME((ROUTINE_INFO('DIST', $ 
   /FUNCTION, /SOURCE)).path) 
 Depending on the platform and location where IDL is installed, IDL prints something like:
 /usr/local/itt/idl/lib 

*FILE_EXPAND_PATH
:得到一个不依赖于平台的完整的路径，等效于file_search中的/FULLY_QUALIFY_PATH关键字

*FILE_LINES
:文件的行数，很有用。

*FILE_LINK

*FILE_MKDIR

*FILE_MOVE

*FILE_SAME

*FILE_SEARCH
:支持通配符

*FILE_TEST
:判断文件是否存在，应该可以替代exist程序
