In this post we will talk about Autocad file formats like *.sv$ and *.sс$. What do they doing and what is the difference between them.
*.sv$ file format AutoCAD using for autosave
*.sс$. file format AutoCad using for temporary files,
Here is the difference between them.
Users can disable autosave from the configuration and in this time *.sv$ will not create. But Autocad creating *.sc$ file regardless user want or not to save it. *.sc$ file need to create normal functionality of software. If Autocad closed safely then *.sc$ file deleting by itself.
If software finishing it works in wrong way then *.sc$ file saving in special detected place. But if we will need to restore some damaged files this file won’t help us. So that’s why let’s take attention to *.sv$.
What do characters mean in autosave filename?
As we talk before AutoCAD autosave file in every time interval that set in configuration. If you ever saw autosaved file you can ask yourself what do numbers and letters mean in the name of the file. Now let’s see explanation
Name_a_b_nnnn.sc$ -> display_1_1_6127.sv$
Name – Name of your drawing
a – number that shows how many times drawing opened in one Autocad session
b – number that shows how many times this drawing opened ever.
nnnn - randomly generated numbers
Where Autocad saves autosave files?
If you get an error while you are working on the project, next time when you will launch Autocad will offer you open autosaved file. This file opening from a place that set in Autocad configuration. Sometimes Autocad not offering open autosaved file that’s because the file had very old save date or Autocad can’t find suitable file. In this situation we should know where we can find autosave file manually
To find autosave file we need first open Options of Autocad.
To do that click on workspace with mouse right button and choose Options.
Switch to Files tab and find from list Automatic File Save Location
Now go to that folder and find your autosaved file.
If your original file damaged you can restore project from autosaved file. To do that you need change sv$ file format to DWG and restore your project.
