# File Minimum

Preallocates disk space for the store file. Preallocation occurs when the server first creates the store file.

You can specify units of MB or GB. Zero is a special value, which specifies no minimum preallocation. Otherwise, the value specified must be greater than 4 MB.

For example:

`32MB`

If File Truncate is set to true, the File Minimum property prevents the EMS server from truncating the file below the set size.

When this parameter is absent, there is no default minimum preallocation.

## Classic Configuration

Preallocate disk space using the file_minimum property in the stores.conf file:

    file_minimum=value

For details on the syntax of stores.conf, see File-Based Store Settings.

## Administration Tool

Stores cannot be created or modified using the administration tool.
