download whole folder

Odisej · January 29, 2018, 4:06pm

Hi,

I’ve been scanning the tutorials and this forum and I can’t find a solution that would answer this simple question… Is it possible to simply download a whole folder with multiple images to temporary / documents directory and delete it if/when need be, or do I need to download and later delete each image individually? Is there any plugin for this kind of thing?

I have managed to create a network request for a couple of images in a table, but this time there are simply to many images in a folder and I have a couple of folders.

thanks for your help

If you can get your folder on the server put into a .zip file, you can then download the zip file with a single network.request API call and then use the zip plugin to unpack it.

However, cleaning up will probably require you to use the LFS API’s and get a list of the files and delete them.

Zip plugin looks to have event.response with listing of the files. I guess one could put those in a table and then delete them:

local zip = require( "plugin.zip" ) local function zipListener( event ) &nbsp;&nbsp;&nbsp;&nbsp;if ( event.isError ) then &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print( "Error!" ) &nbsp;&nbsp;&nbsp;&nbsp;else &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print ( event["type"] )&nbsp; --\> list &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;print( event.response ) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\> [1] = table: 0x618001466580 { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\>&nbsp;&nbsp;&nbsp;&nbsp; ratio: 98 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\>&nbsp;&nbsp;&nbsp;&nbsp; size: 2188295440 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\>&nbsp;&nbsp;&nbsp;&nbsp; file: space.jpg &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\> [2] = table: 0x618001466580 { &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\>&nbsp;&nbsp;&nbsp;&nbsp; ratio: 98 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\>&nbsp;&nbsp;&nbsp;&nbsp; size: 2188295440 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--\>&nbsp;&nbsp;&nbsp;&nbsp; file: space1.jpg &nbsp;&nbsp;&nbsp;&nbsp;end end -- List all files from "test.zip" with additional file info local zipOptions = { &nbsp;&nbsp;&nbsp;&nbsp;zipFile = "test.zip", &nbsp;&nbsp;&nbsp;&nbsp;zipBaseDir = system.DocumentsDirectory, &nbsp;&nbsp;&nbsp;&nbsp;listener = zipListener } zip.list( zipOptions )

but it seems to me this is an opportunity for a new plugin/module for someone who knows more than I do about all this.

I have also discovered os.remove function and it states that it deletes a file or directory:

os.remove( file )

file _(required)

String. String specifying the name of the file or directory to remove.

but if I name a directory containing files it’s not working - only works if the folder is empty, else I get the: Directory not empty in console.

for anyone out there lfs works for deleting a folder as Rob suggested:

local doc\_dir = system.DocumentsDirectory; &nbsp;local doc\_path = system.pathForFile("myFolder", doc\_dir); &nbsp;local resultOK, errorMsg; &nbsp;for file in lfs.dir(doc\_path) do &nbsp; &nbsp; &nbsp;local theFile = doc\_path.."/"..file; &nbsp; &nbsp; &nbsp;if (lfs.attributes(theFile, "mode") ~= "directory") then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;resultOK, errorMsg = os.remove(theFile); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;if (resultOK) then &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;print(file.." removed"); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;else &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;print("Error removing file: "..file..":"..errorMsg); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;end &nbsp; &nbsp; &nbsp;end &nbsp; &nbsp; &nbsp;--[[if you want to remove the folder itself after all the files have been deleted &nbsp; &nbsp; &nbsp; &nbsp;os.remove( doc\_path ) &nbsp; &nbsp; &nbsp;]] &nbsp;end
