To create a shared folder you must first create a project as described in the section called “Projects”. You must then create the initial version for the project as described in the section called “Versions”. Having multiple versions of a shared folder is useful when you want to use different versions of a shared folder in different projects. This is described in more detail in the section called “Updating a Shared Folder”.
If the shared folder files have not yet been added then you should upload the files when adding the version. If the shared folder files have already been added to another project then you should not upload the files. Instead, after creating the new version, you should right-click the new version and select 'Administration | Manage Shared Folders'. Click on the 'Add Shared Folder' button to launch the wizard. You will first be asked to select the folder you want to share.
After clicking 'Next' you will be asked to select the folder where you want to put the files. You will want to put the files at the root of your new version so select the version without creating a folder.
After clicking 'Finish' the files will be added to the new version. You can right-click the new version and select 'Show Files' to see these files. You can right-click the original version and select 'Show Files' and see that the shared folder is using the jigsaw icon.
