Using Drive Syncrypt is very easy

During the first run of the app you will be asked to select a Google account. This is the account the app will use to have access to Google Drive. After that, you need to grant access to Drive Syncrypt to view and manage your Google Drive files. Touch the 'OK' button in the Google's dialog and you are ready to proceed with the setup of sync entries.

You need to setup one or more sync entries in 3 easy steps and the app will automatically keep in sync your files with Google Drive.


Touch the '+' button in the action bar to start the setup wizard. Follow these steps:


Step 1. Select local directory

This is the local directory in your device's external storage (SD) that you want to keep in sync with Google Drive.

Please note that due to limitation of access of external removable SD card on Android KitKat (4.4+) you have to select a directory in your devices storage.

For your safety the root directory of the SD can't be used for sync. You have to select a sub directory. Touching the '+' button you can create a new directory.

Then touch the 'NEXT' button.


Step 2. Select Google Drive directory

Obviously, this is the directory in Google Drive that it will be in sync with the local directory you selected in previous step.

The root directory in Google Drive can be selected only in Premium version. Touching the '+' button you can create a new directory.

Select the directory and touch the 'NEXT' button.


Step 3. Select synchronization parameters.

In this step you may select the different sync methods for the specific sync entry.


Select if the sync point will be active or inactive. Inactive sync entries are skipped during the sync process. You may easily activate or deactivate the sync entry from app's main screen at any time.


Sync type

You may use 3 different sync methods:

  1. Two-way: Changes in both local and Drive directories will be propagated bi-directionally. Conflicts are automatically resolved depending on file modification time.
  2. Upload only: Local directory will be mirrored to Drive directory. Any change in local directory will be pushed to Drive directory but changes in Drive directory will be lost.
  3. Download only: Drive directory will be mirrored to local directory. Any change in Drive directory will be pushed to local directory but changes in local directory will be lost


Instant upload

If you select instant upload, a service will monitor for file changes in the local directory (and sub-directories). Changes in local directory will trigger the sync process immediately.

You may use this option in two-way or upload only sync methods.


Encrypt files on Drive

If you enable encryption (upload only method) local files will be encrypted before upload in Google Drive. Drive Syncyrpt uses the strong AES encryption method with 256 bit key. The key is derived from your password that you may set in app's settings (please see below). The password itself is encrypted with AES and saved in app's private data.

Using encryption, you protect your data and you are sure that no one can access them without your password.

IMPORTANT: If you forget your passwords any access to your data will be impossible. So, please make sure that you will remember it.

Drive Syncrypt will add an extension (.enc) to your files and will upload them to Google Drive. You may download them in your PC and use DSCrypto tool to decrypt them. Also, if you use Drive Syncyrpt from another device and use the same Google Drive directory and same password, the app will automatically decrypt the files after the download.


Exclude files pattern

Using patterns allows you to exclude specific files from sync procedures. You may use multiple patterns separating by comma. Wildcards may be used. '*' for multiple characters and '?' for single character. For example if you want to exclude all jpg files enter the following:


If you also want to exclude all files that filename start from 'Screenshot':


Or combine the 2 above:

*.png, Screenshot*


Touch the 'FINISH' button.

A new sync entry will be created. An info card will be displayed for each sync entry under the main card which displays information about your Google account.

Use long touch to select a sync entry. Then, you may touch the 'Delete' button to delete the sync entry. Of course, this will delete only the sync entry and not your files.

On demand you may use the 'Refresh' button on action bar to initiate a manual sync.
