Hey guys, I put together a little .uno file to allow the use of some [System.IO](http://System.IO) functions in Javascript. It’s kind of like the FuseJS/Storage API but with a few extra functions. [You can download it here](http://jmp.sh/jMVxhxN), hopefully some people will find it useful. ### Documentation #### How to use - 1: Download the FileOps.uno file and place it in the root directory of your Fuse project (the one that contains your `.unoproj` file). - 2: Declare it somewhere in your Main `.ux` file like so: ```auto ``` - 3: Reference it in your JS: ```auto var FileOps = require('FileOps'); ``` #### Available Functions `FileOps.FileWrite("path/to/file.txt", "text")` - Filepath is a string which references the file to be made/written to. Can just be a filename if the file is in the current working directory. - Text is a string which will be written to the file. `FileOps.FileRead("file.txt")` - Returns a string containing the contents of the specified file. `FileOps.GetUserDataDirectory()` - Returns a string containing the path of the User Data Directory. - On Android this is the app’s data folder: `/data/data/com.AppName/files` - On Windows this is the Local App Data folder: `C:\Users\Username\AppData\Local` - I don’t know what it is on Mac/iOS, I don’t have a device to test it on. `FileOps.GetWorkingDirectory()` - Returns a string containing the path of the current working directory. - By default on Android, this is the root of your phone so just: `/` - By default on Windows, this is the folder containing the SublimeText.exe file, in my case: `D:\Program Files\Sublime Text 3` `FileOps.ChangeDirectory("path")` - Takes one argument; the path to which you want to change the current working directory (as a string) - Works like the commonly used `cd` command `FileOps.MakeDirectory("foldername")` - Makes a new folder in the current working directory with foldername as its name - Takes one argument; foldername, which should be a string `FileOps.FileExists("path/to/file.txt")` - Checks if the specified file exists - Returns the result as a boolean; either `true` or `false` - Takes one argument as a string; the path to a file. Can just be a filename if the file is in the current working directory. `FileOps.DirectoryExists("dirname")` - Works the same as `FileOps.FileExists`, but for Directories instead `FileOps.DeleteFile("path/to/file.txt")` - Deletes the specified file - Takes one argument as a string; the path to a file. Can just be a filename if the file is in the current working directory. - Returns `true` on successful deletion. - Returns `false` and logs to the console if the specified file does not exist. `FileOps.DeleteDirectory("dirname", recursive)` - Deletes the specified directory - Takes two arguments; the directory name and recursive - `recursive` should be a string containing the values either `"true"` or `"false"`. Take care not to specify it as a boolean. When true it deletes all directories, subdirectories and files within the specified directory. - Returns `true` on successful deletion. - Returns `false` and logs to the console if the specified directory does not exist. `FileOps.RenameFile("oldName", "newName", overwrite)` - Renames a file `oldName` to `newName` - `overwrite` should be a string containing the values either `"true"` or `"false"`. Take care not to specify it as a boolean. Defaults to false, so you don’t have to specify it unless you want it to be true. - When true, if `newName` already exists, it overwrites it when renaming and returns a boolean `true` on successful rename - When false, if `newName` already exists, it returns a boolean `false` and logs to the console. If `newName` doesn’t exist, it just returns a boolean `true` - If `oldName` doesn’t exist, returns boolean `false` and logs to the console ---

Hi there, I’ve followed your instructions on how to use it, but I get the following error while compiling my project for local preview: `C:\Dvp\App\tw\FileOps.uno(9,24): E3114: There is no identifier named 'NativeModu le' accessible in this scope.
