Once you configure and run Sync, Sync automatically uploads to Liferay DXP any files you add or modify in your Sync folder. Sync also downloads to your Sync folder any file changes by other users. If you delete a file in your Sync folder, Sync also deletes it from the server and other clients. You should therefore use extreme caution when deleting files in your Sync folder. If, however, you accidentally delete a file, all is not lost! The file can still be recovered from the instance’s Recycle Bin, which is enabled by default. Note, if the administrator has disabled the Recycle Bin, recovering deleted files is impossible.
You can run through the following exercise to familiarize yourself with how to
create, edit, download, and upload files with Sync. First, open the Sync folder
in your file manager and create a new file called
README.txt. Enter the word
test in this file. Next, make sure you can access this file in your Site. Go
to the Site you want to sync with and navigate to its Documents and Media app.
It lists your
README.txt file to a convenient location on your machine. Open
the file and check that it still says
test. Now open the
README.txt file in
your Sync folder and edit it so that it says
second test. Once the changes are
synced, go back to your browser and refresh the page with your Documents and
Media app. Click on the
README.txt file’s name, look at the file information
displayed, and check that the file’s version number has been incremented.
If you download and open
README.txt again, it now says
second test. Your
edit was uploaded to the Site! You can be confident that this edit was also
downloaded by all other Sync clients connected to your Site.
Now delete the
README.txt file from your local Sync folder. When the changes
finish syncing, go back to your browser and refresh the page containing your
Documents and Media app. The file is gone! The file is also deleted from the
local Sync folders of all other Sync clients connected to the Site. Remember
this very important rule: deleting files in your local Sync folder deletes them
everywhere! Next, you’ll learn how to use the Sync client for your mobile
