Last Open Time displays the
time it took for the SOLIDWORKS software to open the file, the last time it was
opened. This file property is helpful for managing your time when you have large
data sets that are time consuming to open.
The time displays in minutes and seconds, and is available for models
that are opened directly from disk saved in SOLIDWORKS 2018. For assemblies opened
in Lightweight mode, the tooltip displays Last LW Open
Time.
Last Open Time does not update
in reference files when they are saved while open in memory, but does update when
the reference files are saved while open in their own window.
You can add a column in the Details view of File Explorer to display SW Open Time. You can identify files saved in earlier versions of
the SOLIDWORKS software by adding a column for SW Last
Save with.
