Back the store with a single file
var FSChunkStore = require('fs-chunk-store')
var chunks = new FSChunkStore(10, {
path: '/tmp/my_file', // optional: path to file (default: temp file will be used)
length: 100 // optional: file length in bytes (default: file expands based on `put`s)
})Back the store with multiple files
var FSChunkStore = require('fs-chunk-store')
var chunks = new FSChunkStore(10, {
files: [
{ path: 'folder/file1.txt', length: 12 },
{ path: 'folder/file2.txt', length: 8 },
{ path: 'folder/file3.txt', length: 30 }
