File locators are the same for source and target. They are specified using ordinary path syntax.

Windows Path Syntax

On Windows, paths are specified as either absolute or relative.

This is an example of an absolute path on Windows: 

C:\folder1\folder2\package.ovf

These examples show relative paths on Windows: 

..\folder1\package1.ovf
package1.ovf

Linux and Mac OS Path Syntax

On Linux, paths are specified, similarly, as either absolute or relative.

The following is an example of an absolute path on Linux: 

/folder1/folder2/package.ovf

The following are examples of relative paths on Linux: 

../folder1/package1.ovf
package1.ovf
