You can specify the duration of vaulting by using special folder names. Files in these folders are vaulted for a specific period of time and after that time the files are not vaulted.
To specify duration of vaulting, create a folder named \KeepSafe\ in any vaulted area. In the \KeepSafe\ folder, create folders that indicate the vaulting period. For example, C:\MyImportantDir\KeepSafe\Retain 3 years\. Any file created in that folder are prevented from alteration or deletion for three years. After the expiration time, the file is no longer vaulted. There are three ways to indicate the vaulting period. Each way requires that you use a keyword in the folder name.
Specify exact vaulting periods using English terminology. Duration is specified by a combination of the following time units:
Use 1 or more time units. Each time unit you use must be preceded by a number up to five digits long. You can include spaces or underlines or dashes and mix case in the folder name. The following are valid examples:
\Retain23days4hours\
\Retain 3years\
\Retain_3years\
\Retain-23DAYS_4minutes\
\Retain 1000 days\
\RetainUntil20191231235959\
\RetainUntil 20200101\
\RetainUntil20200101\
\RetainUntil_20200101\
You cannot create a \Retain... folder within a vaulted \Retain... folder.
You cannot move material that is in one vaulted \Retain... folder to a vaulted \Retain... folder that has an earlier expiration date.
