If you received a file through a share and want to remind to consult it again after opening it the first time, you can mark the file as not viewed. To mark a received file as not viewed:

• Access the RECEIVED tab.
• Click on the three-point menu next to the received file you want to mark as not viewed.
• Select the ACTIONS item.
• Select the MARK AS NOT VIEWED item.
• The file will now be displayed in bold as if you had never consulted it.

Note: if you reshared a received file, you can do this operation also on shared files in the SHARED tab.
