Directory Name Restrictions

A directory name must start with either:

It can continue with:

Generally, CA Technologies recommends that path names not be distinguished by case.

Windows specific notes:

Absolute directory names must start with a drive specification (a drive letter immediately followed by a colon), followed by a backward slash \, and then followed by a relative directory path. No UNC paths are allowed.
Round brackets ( and ) can be used after the first character of a directory name, but when installing a manager, round brackets ( and ), and hyphen - are not allowed within the directory name.
Spaces are allowed after the first character of a directory name.
Uppercase letters are not distinct from lowercase letters (for example, A is the same as a).
On Windows, it is not possible to install a manager with a local or remote MDB by using a UNC path name for the image location. If the image location is on a remote system, it must be made accessible as a Windows share. Also, the path name must not contain a @.

Linux and UNIX specific notes:

Absolute directory paths must start with a forward slash / and continue with a relative directory path. A relative directory path contains a number of directory names separated by forward slashes.
Uppercase letters are distinct from lowercase letters (for example, A is not the same as a).
White space (for example, space and tab characters) is not permitted in installation directory paths.
