Projects - Backup file versions

Each time you save changes, a new version of the file is created in your work path, and the previous version moves to the OldVersions\ folder.

Actions when you save file

Several actions happen automatically when you save a file.

• A new version writes to a new file, in the same folder.
• When the new file version is successfully on disk, the original file moves to a subfolder named OldVersions\ in the folder it was in. It is renamed to file name.version.ext, where version is a decimal version number. For example, file name.0003.ext is the name for version 3 of file name.ext. If there are versions 2, 3, 4, 5 and 6 in the OldVersions\ folder, and you restore version 3 to the current version, it is numbered version 7 to avoid conflicts with the existing versions 4, 5, and 6. Problems can occur in future sessions if you delete files from the OldVersions\ folder using Microsoft Windows Explorer.
• Finally, file name.newVer.ext is renamed to file name.ext.

Every save writes a new globally unique version ID to the file to identify it. Each Autodesk Inventor LT session remembers which version ID it is accessing. If you try to reopen the file at the normal location, but the version ID is changed, the program assumes that someone else saved. The appropriate version of the file then opens from the OldVersions\ folder. The version of the opened file is used from that point forward to access additional information.

Uses for old versions of files

You can restore previous versions of files.

The files in OldVersions\ are used for:

• A manual form of error recovery or backups.
• Opening earlier versions of files to load segments. If the earlier version of a file is not found, a message displays, and you Browse or Cancel:

  In Browse:

  Open old version (Save not allowed).

  Restore old version to current version Restores and opens the old version, Not available when the current version is checked out to someone else.

  Open current version The open is redirects to the current version.
