Where Are Autosave Files?

I was working on 3D model for 4 hours and in a sudden the sketchup had shut down. Also I could NOT find any autosave files under original saving folder. I tried search with FILENAME and any other stuff. Is there any way that I can recover my files from the hard drive or anywhere that I can find back-up files?

Please help me figure this out !!!

Your profile says both Mac and WIndows. Which had this problem?

Here’s the general article on where things are saved: http://help.sketchup.com/en/article/36212

Note that on Windows you might have changed the default location, but probably you haven’t.

If you are on Mac, and using SketchUP 2015, you can chose Go to Folder in Finder, and paste this in:

~/Library/Application Support/SketchUp 2015/SketchUp/Autosave


Did you save the model at all during the 4 hours?

  1. Do your SketchUp Preferences have it set up to make AutoSaves at regular intervals ?
    If so they will be named AutoSave_FILENAME.skp…
  • For PC, by default the AutoSave file is saved into your “My Documents” folder - but you can change the location under Preferences > Files > Models… [did you?]
  • For MAC, the AutoSave file is always saved in your User > Library > Application Support > SketchUp # > SketchUp > Autosave folder…
  1. Do your SketchUp Preferences have it set up to make backup files as you manually save a model’s SKP ?
    The FILENAME.skp backup is named FILENAME.skb on PC and FILENAME~.skp on MAC…
    They are kept in the same folder as the original SKP, they are one-save-behind the current-saved model…

If you have neither of these life-lines set up, then it is hoping against hope that there’s a backup… :sob:


You might also find files numbered sequentially 0.skb 1.skb 2skb… It makes these when it can’t write the proper backup file for some reason. Just rename the latest to a SKF file and it should open.

.skb is only written at the time you do a save, isn’t it? It wouldn’t help in a case where no saves have been done.

If the OP hasn’t been manually saving his work, AND there is no AutoSave set up, then there will be no useful files.
If the file has never been saved, then, if it exists, the AutoSave file on a PC would include the text ‘Untitled’, not sure about on a MAC.
It it is an existing SKP that has not been saved then its FILENAME will be in the AutoSave files name [if any].
If Backups are also enabled, then the SKB/~.SKP files will use the file name and be in the SKP’s folder.
BUT if the SKP has not been saved as work progressed during this session, then the Backup file [if any] will contain the model version one-save before the model that was opened at the start of the session. Only saving the SKP makes a Backup.

It’s “untitled” for Mac as well. The OP’s description read like the document had been worked on for four hours without saving, but it isn’t clear whether the file was a new one of a previously saved one.

I am having problem with Windows right now

btw, sorry for the late response !!!

I haven’t saved model during the 4 hours, i know it’s already been two days from my question but I still want to know certain way of recovering/finding missing autosave file. Thanks for helping me !!

I have set up the AutoSaves at regular intervals and it used to saved onto my original folder that was with original files, but some how it disappeared !!! What do you think make this kind of situation??

Backup files go into the same folder as the SKP you are working on, but autosave files go somewhere else. It’s unlikely that you would have kept changing the autosave folder to match your current SKP folder. Look in your My Documents folder for the autosave files.

If you had not saved the model in the four hours that you worked on it, then lost it, there will be no autosave file. You need to save the model right after you start working on it for the autosave function to kick in. Someone correct me if I am wrong.

I am looking for autosave files folder in Windows OS not Mac OS

I have never known that truth, thanks for letting me know and i will start work on that stuff after saving from the next modeling. Thanks for your advise !!!

On a PC, when it’s set up, the SketchUp AutoSave function saves a copy of the model “MODELNAME_AutoSave.skp” at the given time intervals into the folder specified in Preferences > Files - all as outlined in earlier ppsts…
However, when you exit the model ‘cleanly’ [with or without a final ‘save’], then its AutoSave file is usually auto-deleted.
If SketchUp crashes the model’s AutoSave file is usually left behind - so in theory you can rescue some work, at least back to the last time it was AutoSaved.

On my PC with AutoSave set up, I open a new ‘Untitled’ model from a Template, and I do not save it… after the requisite time has passed an AutoSave file IS made - it is named “AutoSave_Untitled.skp”. If I then close this model [with or without saving it], then its AutoSave file is auto-deleted, as it closes…

If you have SketchUp’s Backups set up [on PC that makes SKB files], then you can go back the the model-version one save behind your last save [you just rename the SKB as a SKP].

Of course if you haven’t been saving your model you can’t expect miracles…
It was complete insanity to never save any of your work over a four hour period - sorry to be harsh !
AutoSaves do NOT persist after the model is cleanly closed - only if it crashes/splats…
