A project snapshot is a .TEWZIP archive embedded in the project folder. This is the full content of a electrical project database and files, not only a differential compared to the previous snapshot.

A snapshot can contain the external dependencies of the electrical project (library items such as used symbols or title blocks).


A snapshot is an electrical project backup done at a special time, such as a new revision index creation. The snapshot offers the possibility to restore an old version of the electrical project, it must not be confused with the electrical project archive.

Snapshot and electrical project archive comparison



electrical project archive

Folder and filename

The TEWZIP file is saved automatically in a directory depending on the project folder. The snapshot filename is automatically managed by the software.

The electrical project filename (TEWZIP) and the saved folder are managed by the user.

Dependencies (All elements used to create the electrical project, such as symbols or title blocks)

When you create a snapshot you can include (or not) the dependencies. If the snapshot is restored in the same workstation, it is not necessary to include the dependencies.

The dependencies are automatically included in the archive file.


The snapshot files are managed automatically by the software through the Snapshot Management dialog box.

The user has to manage by himself the electrical project archived files.

Electrical project exchange

Do not use a snapshot file to exchange an electrical project with another Company.

Only use the electrical project archive to exchange the electrical project with another Company (contains dependencies).
