Exclude files from synchronizing across devices

inSync Cloud Editions: File:/tick.png Elite Plus File:/tick.png Elite File:/tick.png Enterprise File:/tick.png Business

Overview

As a cloud administrator, you can decide and exclude certain files from being synchronized across all users' devices.

If a Share user uploads a file and then that file is excluded from synchronization, inSync stops synchronizing the specified files starting from the next inSync Client backup. The backup can be either a scheduled backup or a manual backup.

How does the file exclusion work?

After you exclude certain file types from synchronization, you can:

  • Disable excluded files from being synchronized across users' devices.
  • Control the sync process, such that only the required files are available across all devices.
  • Save space on the quota usage of the share user's account. For example, by excluding .pst files from synchronizing with the share user's account.
  • Save space on the collaborator's device. For example, by excluding .pst files from synchronizing across collaborator's devices.
  • Stop continuous synchronization of files that get updated regularly. For example, .url files and .eml files.
  • Prevent the owner's credentials from being copied to the collaborator's synchronized folder. If the owner credentials of a shared folder is copied to the synchronized folder, then the shared data becomes inaccessible to the collaborator. For example, by excluding credDB.cef files that copies owner's credentials.

Which files are not synchronized by default?

By default, inSync Share does not synchronize the following file types: 

File type Description

Temporary file names

Files or folders with the following invalid prefix name list:
.~inSync$, ~$, .~, ~inSync$

Temporary files created on the computer

Files or folders that with the suffix .tmp or .smp.

System-specific files

For example, files such as desktop.ini, .DS_Store, Icon\r, and thumbs.db.

Files created by Dell security solution

File with the name credDB.cef.

The file contains user's access credentials, and is created in every folder on the computer. 

File or folder names that include special characters Files or folder names that contain <, >, :", |, ?, *, \r, \n, or ^.

Which files are recommended to be excluded from sync?

To save space on the share user's quota usage and disk quota usage as well as to avoid continuous synchronization by inSync client, we recommend that you exclude the following file types from sync:

File type Description Why to exclude
Microsoft Outlook data file

Files with the suffix .pst.

 

These files are generally large in size, around 1 GB or so, and get updated regularly. 

Email files

Files with the suffix .eml.

These are email files that are sent or received by a POP3 email application.

The Windows Search Service and Indexing Service keeps modifying these files regularly, which result in large number of versions created for the same file. Additionally, the inSync client keeps on syncing these files. 
Internet shortcut files

Files with the suffix .url.

These files are used by web browsers, and get updated regularly by a few antivirus applications.

The Windows Search Service and Indexing Service keeps modifying these files regularly, which result in large number of versions created for the same file. Additionally, the inSync client keeps on syncing these files.
