Accepted file names and UNC names
The operating system determines what kind of file names and paths are acceptable.
File name length (NTFS disk) may be 255 characters long, path and extension included. The following characters are forbidden:
< > : " / \ |
Note: We urge you to carefully consider about the use of long file names, especially if you expect to use the files in programs that do not support long file names. These programs will truncate the names to 6 characters and a running number: First 6 characters+%+ a running number.

Long file name |
Short file name |
---|---|
Example drawing for manual.drw |
Exampl%1.drw |
Example drawing.drw |
Exampl%2.drw |
Example of a relay.drw |
Exampl%3.drw |
1234567890.drw |
123456%1.drw |
UNC names
Program also supports UNC names, that contain the name of a network resource (for example, \\server1\archive). This is useful because:
-
The defined network resource appears the same for all users, regardless of which disk drive has been defined for the resource in question. For example, in an archive system, that saves drawings with their complete path, this is the only way to create workstation-independent paths.
-
A long path name can be shortened by defining a network resource name for it.
The UNC name format is \\server_name\resource_name\path\file.

If a server named serv1 has a resource named archive, and in it a folder named project1, a path retrieving a file named plan1.drw from that folder would be:
\\serv1\archive\project1\plan1.drw
This name (without the extension) can be entered to open a file.
