Locate your cached files

When you open a file with UFO or AFO, the file is stored in a local repository known as cached files. The default location for the cached files is:

• On your PC:
  C:\Users\<LocalUser>\.syncclient\<uniqueID>\youremailaddress@domain.com
• On your Mac:
  /Users/<LocalUser>/.syncclient/<uniqueID>/youremailaddress@domain.com

View and access cached files in the UFO status dialog

1. In Google Drive or AODocs, click the UFO extension button next to the URL bar. If you have one or more files in your cache, the list of cached files is displayed.

Notes:
– By default, cached files are sorted by the last modification date. You can sort your cached files by their name, last modification date, size, or whether they are pinned to be permanently available offline.
– If you have no files in your cache, the status of the UFO extension is displayed.

2. Check the file icon to see its lock status:

	No padlock The file is unlocked. You can lock it by opening it locally.
	Red padlock The file is locked by you. Only you can edit the file.
	Gray padlock The file is locked by another user. The email address of this user is displayed when you hover over the file icon. Only the user who locked the file can edit the file.

3. Select the name of a file that isn’t locked by another user to open and edit it locally.

• If you open a cached file that hasn't been edited by another user, the file is opened directly from your cached files.
• If you open a cached file that has been edited by another user, the file is downloaded again to your cached files.

Manage cached files in the UFO status dialog

Note: When you initialize the UFO extension, a cleanup of your cache is performed:
– if your cache contains either 100 files (default) or the maximum number of files defined by your administrator, the least recently modified files are removed
– files that haven't been modified in the last 30 days are removed
However, if you choose to keep files in cache (see step 2), the above conditions no longer apply.

1. In Google Drive or AODocs, click the UFO extension button next to the URL bar. If you have one or more files in your cache, the list of cached files is displayed.

2. The following features are available to manage your cached files:

	Version history button to open a page where you can access the Drive version history of the file in Google Drive
	Locate in Google Drive button to open the parent Google Drive folder in a new tab
	View details button to open a side panel with information about the file, such as details about the lock, file size, owner, last modification date and creation date
	Remove button to remove the file stored locally in your cached files
	Pin file in cache / Unpin file in cache toggle: when pinned, the file remains permanently available in your cache and you can access your cached files when working offline; when unpinned, the standard cache cleanup conditions apply
	Delete stored files to remove all the cached files

Notes:
– If you remove a locked cached file, the lock is released.
– You can’t remove a cached file if it is open in your local software.

3. Click Back to display the status of the UFO extension.
