Synchronize Local Files / Folders with Google Documents Using KumoSync

KumoSync is a Windows application used to synchronize local windows and files/folders with Google Documents. You can sync any document/file format.

Before You Get Started

First: Make a backup of your local files you plan to sync with Google Documents. You can additionally export your data from Google documents as well. This way as you work through how you want KumoSync to sync your local folders with Google documents you will not lose any files.

Second: Many may notice that in Google Documents there are groupings called “collections” which appear to function like a typical folder. These “collections” not like local file folders are more like tags or categories used as a way to group or classify your documents.

For example, a single Google document can exist in multiple collections whereas on the local file system this is not possible; the same file would need to exist as a _copy_ in each of the local folders.

Configuring the Sync Process

Once KumoSync is installed you’ll find a KumoSync icon in the windows system tray that allows you to control the overall sync process including manually performing the sync, editing your settings, and quick access to your local folders configured for synchronization.

To start configuring KumoSync select the “Settings” option which will then display the main KumoSync settings dialog. From here you can configure the sync ‘mappings’ that link your folders with Google document accounts, set you general sync preferences, adjust any settings related to using a proxy server, review your registration information and find out about the current product.

For the moment select “Sync Mappings” and then click the [NEW] button to create a new document sync mapping.

A new dialog will appear allowing you to configure the sync mapping. The basic idea is that you will map a local folder to the Google documents “All Items” list or to a specific collection.

To get started enter your Google username/password, select the appropriate Google Document list you want to sync with, select the local directory you want to sync with and then optionally configure a drive letter that you want to map the local folder that will contain your local/Google documents.

Following this you can then adjust any additional settings on the sync options, permissions, and other tab as needed. In most cases these options can remain as defaults. On only option that may be of interest is the ability to control the sync direction. On the sync options tab you an set either one or two-way synchronization.

At this point you are basically done and ready for syncing. You can either click sync from the KumoSync system tray or use the Sync Options panel on the KumoSync settings dialog to configure automatic synchronization. [source]
