Update lost all

Cannot find or gravitate to any previous files. Will not open documents.

What do you mean as “Update”? Is it an operating system update, or some LibreOffice update? (Which version from, and which version to?)

Only get to “Welcome to LibreOffice” page. Nothing beyond that. My files are on the computer, just not available with Libre.

Do you mean that the File - Recent documents list is empty on the Splash screen of the LibreOffice? Or there is not any document Icons on it?

If the Splash screen and the Recent documents list are empty, then your User profile has been resetted.
Use the File - Open feature. Navigate to the place where you have saved your documents, and choose and open the file what you want to open.

Liibra4me and Villeroy – Have your tried to use the computer’s “File Manager” to find your files? You can find and organize all of your documents (files) using the File Manager (or whatever it is called in your Operating System). You can also Open any of your documents using the File Manager! Some documents can be opened by more than one program (application), but using File Manager you can choose which program to open any of your documents. File Manager is like magic! It gives you control, and it assumes very little. Use File Manager.
