This ensures that the history remains transparent at all times. A new version is automatically created every time a change is made to the document. You can open the details and version history division using the document’s options. | The version number also increments if the document's content has not been edited but, for example, metadata has been added or tasks have been created directly from the document. ![](https://storage.crisp.chat/users/helpdesk/website/-/e/9/9/f/e99f84472c42a000/2def4d81-ef5e-48b4-8e70-45d6e4_pjl8v4.png) The entire revision history is displayed there. Overwritten versions remain available in the history. If an older version is opened, it can be restored. ![](https://storage.crisp.chat/users/helpdesk/website/-/b/2/9/3/b2939f8281c24800/3f0f373c-6f86-4758-ba86-e90af9_926185.png) > Document versions, revision history, restore version, file history, document management, view older version, version control, track file changes, update document, open older version ### Contents Version History The version history documents various types of changes. This allows for complete tracking of all activities related to a document. ****Changes to the document's content**** The content of Word, Excel, IFC, and PDF files is versioned as soon as changes are made. ![](https://storage.crisp.chat/users/helpdesk/website/-/3/5/d/2/35d21efa57fb8600/2eeeee99-3720-4551-ba33-4466b0_3kc49q.png) ****Changes to Categories and Status**** Changes to [Categories](/en/article/project-settings-1rjsa05/) and its status are saved in the version history. ![](https://storage.crisp.chat/users/helpdesk/website/-/f/a/2/b/fa2b2a10a8cff00/5bb9e49a-a80d-4819-bc14-76c5db_1lturp4.png) ****Tasks, Information, and Topics Related to the Document**** If a [Task, Information, Topic](/en/article/overview-of-tasks-topics-mthdcc/) or comment is created for the document, it is also saved in the version history. ![](https://storage.crisp.chat/users/helpdesk/website/-/6/0/5/4/60540db820943c00/11702134-cc79-4692-8079-39385b_100gyc6.png) ****Exam Questions**** Creating and customizing [Exam Questions](/en/article/reviewing-and-approving-documents-1x9xa4y/) are saved as a document. ![](https://storage.crisp.chat/users/helpdesk/website/-/e/8/2/8/e828a5132e44e000/12cbd07f-0736-496a-bfea-b53e81_xc4mpw.png) ****Sending Documents to External Parties**** The sending of a document to external recipients is logged in the history. Detailed information [Shipping Information](/en/article/sending-documents-to-external-contacts-1kbwrau/) can be viewed via this entry. ![](https://storage.crisp.chat/users/helpdesk/website/-/b/a/5/c/ba5ccdad97787800/5dc414bc-892e-4814-9d63-1f51fa_q4xdgz.png) ****Plotting Documents**** The plotting of a document is recorded in the version history.

The respective element can be opened directly from the model view. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/2/9/f/d29f517da520580/versionsverlauf-des-modells_6zboay.png) ### Version History When Overwriting Files ****Replace by Uploading**** When uploading, a file can replace an existing version. If a file with the same name is uploaded from a local location, a new version is automatically created from the file already present on buildagil. For more information on overwriting documents, see the following article: [Uploading Folders & Documents](/en/article/uploading-folders-documents-all435/). ****Replace by Copying Within the Project**** If a file that already exists in buildagil is copied within buildagil to a folder that already contains a file with the same name, a message will appear. This message allows you to choose whether to overwrite the existing file or keep both versions. ![](https://storage.crisp.chat/users/helpdesk/website/-/d/2/9/f/d29f517da520580/dokument-ersetzen_uzjwzw.jpg) When overwriting in this case, the existing version history is not retained, since the existing file is completely replaced by the copied file. > Document changes, status history, category changes, task log, proofing history, external document approval, shipping tracking, plot history, change log, document activities
