Manually delete old .tmp files from hidden folder to free up disk space!

Just a house-keeping tip that I thought other people might find helpful:

I finally found the hidden folder that houses the auto-recover files created when Storyline 2 crashes and I was astounded to discover that there were more than 20GB of files in there!  That explained why my virtual machine was always using up 3-4 times more space than I thought it should, based on the files and programs I had installed on there.  It appears that, although Storyline automatically creates the .tmp files, it does not automatically delete them when newer files are created, so it is a good idea to check that folder on a regular basis and delete old versions that are no longer relevant to keep them from hogging all of your hard drive space.

For anyone who does not know how to find a hidden folder in Windows (I'm using Windows 7), open a folder window and click on the 'Organize' pull-down menu at the top-left of the window and choose, "Folder and search options".  In the window that pops up, go to the 'View' tab and click the radio button beside "Show hidden files, folders and drives" under "Hidden files and folders", then click 'OK'.

Now, go back to your folder window and look for the path: /AppData/Roaming/Articulate/Storyline (it may differ for others but I found it under C:/Users/[my user name], then AppData/Roaming/ etc....).

Articulate staff member, Ashley Terwilliger, mentioned this path in another post about finding auto-recovery files (
If there are unsaved pending changes, an auto recover file is created for the project under the /AppData/Roaming/Articulate/Storyline path. This auto recover file is named using a format like this:
<name of the file witout .story extension><creation time stamp of the file>.tmp

So if you were working on a file called "my sample story.story" the auto recovery name might look like "my sample story635502380729253410.tmp".

I deleted all of the old .tmp files except for the most recent one for each of my projects and it freed up a lot of room and made my whole system run a lot faster.  I have now made a shortcut directly to that folder that I keep on my desktop so I can go to it on a regular basis and clear out whatever isn't needed anymore.

Hope that helps someone!

Has this issue with .TMP files in the C:\Users\<username>\AppData\Roaming\Articulate\Storyline directory been addressed yet?  My users are still having this issue.  The .TMP files keep piling up until the C: drive is completely full.  Having to navigate through Windows system folders in order to manually clean these up is really not an acceptable solution. 

Ashley, if there is something else I need to do in order to fix this, please let me know.

Hi there, David. So sorry the .tmp files are not getting deleted.

I opened a support case on your behalf, so our Support Engineers can do a deep-dive on your setup. They're rockstars at identifying the cause of such issues, and I'll follow along so I can share any valuable updates information here. Thanks again for reaching out, and keep your eyes out for an email from!

This was just happening to me using the latest version of Storyline 3, and I am on the  latest update . Our IT  Staff used a program called TreeSizeFree (portable version, free shareware).

I went from having less than 2gb free to having over 60 gb available. 

I'd be happy with a utility that would go in and clean these out within the Storyline application at this point.

I'll email support and let them know as well.

I saw a note above that " this was fixed in Update 4 of Storyline".

Whatever the fix was, it appears to be gone.  I am working with very large Storyline files (often over 1Gb) on Windows 10, and I need to regularly go to the cache folder to delete the tmp files so that I don't run out of disk space.

Another disk space issue with Storyline:  When starting a new session of storyline, it forces download of older storyline files from OneDrive, even so I am not attempting to open these older files and I have marked them as "Free up space" in OneDrive. (and Storyline is using large network bandwidth in doing so, since these older files are over 1Gb).

I have the latest version of Storyline 3 (3.6.18134.0) and Windows 10 1809.

Articulate should do a better job cleaning up after themselves, and should not force downloading of unnecessary files.

That is for Storyline 360. I actually have to clear out my API cache all the time. Usually gives 1-1.5 GB of precious HD space on my computer. I literally could do it everyday I work in Storyline, and sometimes I have to. :(

I delete the V1 folder under that tree. I am on version 3.18.16449.0.

Hi Sebastian,

Thanks for reaching out! 

Some temp files are kept as part of the auto-recovery process, but if you see these and Storyline has not crashed, I'd love to have you work with our Support team to help figure out what's happening with your setup. 

If you do reach out, let me know, and I'll follow along in your case, too, and update the forum discussion!

I have spent several weeks trying to figure out why my 260GB C drive was grinding to a halt whilst actively building Storyline courses... I have all SL files and all other system data loaded onto my D drive (1TB), but because Articulate software has to be installed on the C drive, this is where is loads all temporary files when the programme crashes.

Storyline crashes regularly, probably every 15 to 20 minutes, it only happens on my new top-end laptop, as I think the Articulate software is a little old now!  I found that if I regularly exit and save the application every 15 minutes or so (and regularly save in between), then I don't get caught out.

However, it does catch me out now and again and over 6 months or so I found (through a local computer firm called Alcom who ran diagnostics) that over 160Gb of temporary files were on my C drive... hence the slow decline of my system performance and only a few Mbs left on my C drive.

Have removed all temporary files and hey ho... system now okay.

Storyline is a great product, but you guys really need to invest in bringing the architecture/software it into the 21 Century!

Totally agree!!!!!!!!!!

My hard drive was running out of space and I finally discovered Storyline temp folder with 200Gb of temp files...

My Storyline 360 crashes also very often, copying a trigger, moving objects, whatever you do is a potential risk of crashing Storyline and loosing a lot of work.

I can't beleive these guys from Articulate didn't solve this issue 6 (SIX) years after the first report... And this happens with many other things... Storyline is full of bugs and nobody fixes them...
