Do not attempt to edit templates created in iManage Control Center using classic iManage Work Web. The templates will not function as expected.
If you have existing templates with variables with the "#" delimiter, you can continue to use them with Workspace and Flexible Folders. If you want to use them with iManage Work Workspace Generator, you must change the variable to use the "%" delimiter.
Flexible Folders do not recognize the folders created by iManage Work Workspace Generator as a standard part of the template and allows users to create them again. As a best practice:
iManage Work Workspace Generator: Define the prefix/suffix in the folder Name property.
Workspace creation: Define the Folder Prefix/Suffix template property so that you do not have to duplicate values in folder names.
Flexible Folders: Either the define prefix/suffix in folder Name property or the Folder Prefix/Suffix template property as both support the workspace generation methods described above.
