Folder

Represents a folder on a file system. You'll never instantiate this directly, but will get it by calling FileSystemProvider.getTemporaryFolder, FileSystemProvider.getFolder, or via Folder.getEntries.

Example

Copy
// Get the Folder instance via localFileSystem
const fs = require('uxp').storage.localFileSystem;
const folder = await fs.getTemporaryFolder(); // Gets the Folder instance
console.log(folder.isFolder); // returns true
Copied to your clipboard
// Get the Folder instance via localFileSystem
const fs = require('uxp').storage.localFileSystem;
const folder = await fs.getTemporaryFolder(); // Gets the Folder instance
console.log(folder.isFolder); // returns true

isFolder

getEntries()

Returns an array of entries contained within this folder.

Returns: Promise<Array<Entry>> - The entries within the folder.
Example

Copy
const entries = await aFolder.getEntries();
const allFiles = entries.filter(entry => entry.isFile);
Copied to your clipboard
const entries = await aFolder.getEntries();
const allFiles = entries.filter(entry => entry.isFile);

createEntry(name, options)

Example

Copy
const catImageCollection = await aFolder.createEntry("cats", {type: types.folder});
