file.deepReaddirSync('/path/to/read') // {files: ["/path/to/read/a.jpg", "/path/to/read/b/c.jpg"], directories: ["/path/to/read/b"]}
file.deepReaddirSync('/path/to/read', {maxDeep: 0}) // {files: ["/path/to/read/a.jpg", "/path/to/read/b/c.jpg"], directories: ["/path/to/read/b"]}
file.deepReaddirSync('/path/to/read', {maxDeep: 0, isRelative: true}) // {files: ["a.jpg", "b/c.jpg"], directories: ["b"]}

options

• maxDeep: number (default: 5)
  • max search number for deep. 0~
• ignoreSystemFile: boolean (default: true)
  • not exists system file
• isRelative: boolean (default: false)
  • response value to relative.

makeFiles (filse, current = '.')

create any files.

// create files ./a.txt(text a), b/b.txt(text b)
file.makeFiles({"a.txt": "text a", b: {"b.txt": "text b"}})

checkFiles (files, current = '.')

renameSyncBySearch (file, pattern, replace)

var change = file.renameSyncBySearch("./sub/abcdabcd.txt", /[bc]+/g, "ZZ") // { old: './sub/abcdabcd.txt', new: './sub/aZZdaZZd.txt' }

fillNumbersByMaxlengthUnderDirectory (directory = '.')

it's search all files name. and get max length of number.
finaly change files number to max length.

file.makeFiles({sub: {"aaa012.txt": "", "aab12.txt": ""}})
var change = file.fillNumbersByMaxlengthUnderDirectory("./sub") // [ { old: './sub/aaa012.txt', new: './sub/aaa12.txt' } ]

file.canWrite ("/existsDir/noExists.txt") // true
file.canWrite ("/noExistsDir/noExists.txt") // false
