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.
In Windows 10, Windows Explorer was renamed to File Explorer.
