HUGE OfficeFileCache Folder

    Question

  • I was over quota on my cloud backup server and finally discovered the cause. My OfficeFileCache folder has grown to an immense 48.8 GB! Here are the vitals:

    Computer: Acer Aspire running an Intel Core i3

    OS: Windows 8.1 Pro

    Office Software: Office 365 Home Premium (version 15.0.4569.1508)

    I was a regular user of SkyDrive (OneDrive) but I now use the Box cloud server instead. I do nonetheless have some less critical files still stored on OneDrive - they total 35.4 GB of data, most of which are MPEG audio files.

    My Box folder contains 11.0 GB of data and these are primarily Office derived documents.

    Even together, these files are not equal in size to the Cache!

    What in the world is going on with the cache and how do I tame this beast?

  • Hi David -

    I am experiencing the same issue.  End user told me today he only has 2GB's available on C:\.  I found that his \OfficeFileCache folder is 71GB's!!!  Obviously i'm here because i'd like to know whether Microsoft recommends deleting these .fsd files - other forums have suggested that it's ok, but first one needs to stop (or pause) the Groove service.  As this machine belongs to the CFO of our company, I want to be completely sure that this wouldn't have adverse effects. 

    Open to suggestions.....

  • Anyone feedback on this one? I have a similar feedback from a customer which states that if you have 10GB in your OneDrive for Business this actually occupies twice the space on their local drive. I thought that this should only be the local cached files (which were opened in Office during the last 15 days by default),

    Rgds,

  • I too have the same issue. OneDrive for business has saved over 70GB of thousands of .fsf and .fsd files in the "C:\Users\Username\AppData\Local\Microsoft\Office\15.0\OfficeFileCache" folder.

    I keep deleting them but thousands more come back again. I have uninstalled twice now with same issue. I click on the Repair option and it says "it cannot backup all of your work files and any local changes due to insufficient disk space". If OneDrive would stop saving several thousand of these files, then I would have enough disk space.

    Come on Microsoft. What is going on here? What do we have to do?

  • Danny - If you go into your Microsoft Office Upload Center => Settings.  Change the cache settings:

    Days to keep files in Office Doc Cache =1

    Select "Delete files from the Office Doc Cache when they are closed.

    Select "Delete cached files". 

    I believe that this will help keep \OfficeFileCache folder to a minimal size.  I'm currently synchronizing my OneDrive for Business, plus three (3) SharePoint Document Libraries - my cache maintains a 7GB size.  It no longer grows to 50GB, 60GB, 70GB+ as before. 

    Let us know if this works for you. ~Tom

  • Hi Tom.

    I have the same problem. I have already tried setting the options you selected but my cache is still huge.

    Do you have any further suggestions? This is a real issue for those with smaller hard drives such as SSD's in a Surface Pro.

    Richard.

  • Hi Tom,

    Thank you for your advice. I have tried these settings but still there are thousands of these small files.

    The aim eventually is to get a small company of around 60 staff that I manage the IT for to start using this tool. However, As Richard has pointed out, most of the computers and laptops have smaller SSD drives and if they are office PC's with as much as 60 profiles saved on each machine as they roam, this is going to be a no-go I am afraid.

    I have now uninstalled OneDrive for Business and back to using the personal version of OneDrive as this does not have any of these issues at all. I understand they are different products and I will loose SharePoint functionality by not using OneDrive for Business, but Ce la vie.

    Thank you again Tom,

    Danny

  • Good luck... all of us here feel your pain.
    Monday, August 4, 2014 2:33 PM
  • Same issue.. just synced a few gigabytes of data last night to OneDrive for Business from my F: drive, now I have a few gigabytes of cache files sitting on my C: drive (SSD.) Again.. I can not spare the space on my SSD like you guys. 

    I tried going into the MS office file uploader and changing cache settings, clearing the cache, and it literally does nothing. 

    Eagerly awaiting an answer... this is an unacceptable waste of space.

  • See this discussion.

    https://community.office365.com/en-us/f/154/t/248984.aspx

    This behaviour is by design. You have 300GB on OneDrive for Business? Do you decide to sync them locally? Well, you'll get 600 GB on the local drive and there is nothing you can do about it... except waiting for the next ODB version and hoping this will fix; my question is... why OneDrive (the free one) does not have this problem...?

  • Tom Nicke - this is not the solution of this problem. Microsoft Office Upload Center uses some other cache than the mentioned above.

  • Same problem here.  I have synced 50GB to my ODB account and my officefilecache is 60GB.  I mean really! Who in the world programmed this crap?
    Thursday, November 27, 2014 9:29 PM
  • Same problem. Is there any fix?
    Monday, December 8, 2014 11:47 AM
  • I wrote my own program that deletes all FSD and FSF files if they are older than 5 minutes. I had some trouble with backing 500GB of photos/videos from D: because the offline cache kept filling up my C: which runs on a SSD.

    I've put it up on github https://github.com/ajtowf/OfficeCacheCleaner, I just updated the implementation so it's installed as a windows service. 

    I also blogged about it and you can read about it here http://www.towfeek.se/2014/12/office-365-onedrive-offline-cache-size-problem/

    Hope it helps!

  • Hello All,

    Hopefully a clarification:

    Microsoft Office Upload Center cache is VERY different from the issue here. Thus any settings there will not change the huge space required on your C drive for the OfficeFileCache folder. This and other issues are caused by sloppy MS programmers. I vote for Ajden Towfeek's solution which is a pragmatic solution for the ignorant lazy programmers at MS.


    Best regards George

  • Thanks George, don't forget to vote also ;-)

    Sorry for the spam guys I didn't realize how the commenting system worked in these forums, I deleted all my duplicate answers.

    Also I just updated my application to run as a windows service instead and it's installed by simply double-clicking a msi, still to be found at https://github.com/ajtowf/OfficeCacheCleaner, you can also read more about it at http://www.towfeek.se/2014/12/office-365-onedrive-offline-cache-size-problem/.

  • Hi Ajden,

    Possibly a stupid question, but will deleting the FSD files affect my local sharepoint libraries at all?

    I have about 20 sharepoint libraries synced on my main pc. The last time I tampered with the office cache on this pc (I think I deleted the entire "AppData\Local\Microsoft\Office\15.0" folder, following advice on the forums here, when I was having difficulties with certain files not syncing) it ended up causing all of my libraries to stop syncing forcing me to re-sync them all over again.

    I've had so many problems with sharepoint over the last few months that I'm paranoid that tampering with anything will bring new headaches!

  • Another option if you have an additional disk apart from C: is to create a symbolic link and move OfficeFileCache away from C:

    That requires you to first kill a number of services and keep them closed:
    taskkill /IM groove.exe
    taskkill /IM msosync.exe
    taskkill /IM msouc.exe

    Then move the content of the cache to the new location, delete the folder
    C:\Users\<user>\AppData\Local\Microsoft\Office\15.0\OfficeFileCache, run
    mklink /D C:\Users\<user>\AppData\Local\Microsoft\Office\15.0\OfficeFileCache E:\OfficeFileCache
    and start Onedrive again

  • Thanks Ajden.

    I've just installed your application.  I'm crossing my fingers.  If it works, then you're a lifesaver!!!!!!!!

    Also, you might want to include in your instructions how to change the folder security options to enable saving the config file to the app folder.

    Thanks again!!!

  • This is absolutely ridiculous!  I'm about ready to reformat and reinstall.  Microsoft needs a "real" fix for this now.  Items in triplicate is not the point of OneDrive for Business.  Why on earth do I need them stored locally and in a cache if it is SUPPOSED to be in the cloud.  Which I might add is the really the whole point of the cloud, to be accessible anywhere WITHOUT cluttering up my OS partition with an extra 40GB of data that is virtually stale.  This is a step backward.

  • No only is the cache huge, but the one drive folder itself has the actual files themselves.  So basically my C drive has over double the memory allocated for the same thing?

  • This is "by design" (that is: Poor Design). Either get a huge disk and live with it or switch to another cloud service. I switched to Dropbox 6 months ago and there you have good software design.

  • Fix this already Microsoft for the love of all things holy. I just signed up to o365, 1TB OneDrive for Business. I dropped 250GB of stuff into it (off a 3TB HDD I have) and was very surprised to see ~250GB of FSD files appear on my C:\... ridiculous double data handling.

    Basically to backup this 250GB of data I need 500GB of local storage.. half of it on my valuable SSD... DropBox doesn't do this, SpiderOak doesn't do this... fix it!

    By all means store the metadata on the C:\ if you have to but the FSD file should not exceed a few KB each ... a pointer should be made that is just the path to the actual file on my other local drive.

    Wednesday, December 16, 2015 10:14 AM
  • Thanks the symlink idea is great, but it still means I need 2TB of local storage to keep 1TB of data in OneDrive for Business. Terrible terrible terrible design...
    Thursday, December 17, 2015 12:01 PM
  • Symbolic linking was the perfect solution for my particular situation.

    Had to close different programs than quoted above, since I was running OneDrive for Business, but the procedure was the same otherwise.

    Thank you, George!

  • One Drive really is quite pathetic software. Nearly 2 years later, and still this is not fixed. I've tried several times to sync a 3GB~ folder and it never works, just shows in my taskbar that it's still trying to sync 12k files even after letting it sit for a month! I've reset everything multiple times and started from scratch, still with no luck. I finally gave up and was just cleaning up stuff, now to find nearly 30GB of these cached files. It really is sad that MS puts out a program like this and thinks it's acceptable. 
    Wednesday, January 27, 2016 8:24 PM
  • Two years later... The problem is still not fixed. On a business software that supposed to compete with dropbox... THis is quite astonishing.

  • My understanding is that this double-file bit is two-fold: it facilitated SOAP on Windows 8.1 (delta save only) and also enables simultaneous authoring by merging changes with the "real" file.

    I think I read SOAP is dead in Windows 10; if so, that's unfortunate.  It can be tested easily enough (if large files sync'd to hard drive but File Opened from OneDrive save quickly on the second save then its working.)   

    IIUC  the OneDrive option "Use Office to Sync Office Files" kills the sharing function and keeps the cache from forming.  You'll probably have to delete the existing cache yourself.   If someone tries please report back.

  • Hi People,

    I seem to have stopped all these files appearing in the "AppData\Local\Microsoft\Office\15.0\OfficeFileCache" folder.

    The way I did it was to go into the Onedrive settings by right clicking the task bar icon, un-tick the setting under the office tab that says "Use office to sync office files" then remove all the fsd,fsf files manually.

    I then end tasked MS Upload centre and Onedrive and re-loaded them and the problem was gone.

    Hope this helps other people.

    Cheers

  • Microsoft you bastards - come on this issue seems to exists since 2014 and you are still unable to solve this. My servers SSD was completely filled up by these fucking FSD files (a whopping 176 GB!!!!!) just because I used One Drive Business to sync our Photo Library with Sharepoint! I would totally use some other client but now - it seems there is no other client available to connect to sharepoint (apart from Windows Explorer but that doesn't work on a Windows Server either because of some "very sensible" security settings which I wasn't able to change).

    Also I don't think Ajdens solution is very good for the SSDs life, if I keep writing these files and the other app keeps deleting them I'm pretty sure that this is going to make my SSD Wear quite high!

  • I too am having this problem. My SSD is filled up with over 100GB of this crap. Why won't MS fix this?
    Thursday, April 13, 2017 11:42 PM
  • Thanks so much for this. It's not a perfect solution, but at least it gets the cache off my SSD boot drive.
    Friday, April 14, 2017 2:14 AM
  • Seems that they can't be bothered... I am going to start looking at alternatives and get in touch with MS for a refund under the failure to deliver a service... maybe that's what we would all do.  How MS can let this problem keep rolling for years without fixing it amazes me.  ODB with SharePoint seems such a great idea, but not when my disc space disappears consistently.  Anyone tried BOX or Google Drive?  I've been using BOX with a client and so far it seems OK so far.

    I tried to make it keep documents only for 1 day, but the setting won't stick.

    Anyone who suggests that doing a clean reboot to fix a problem is just passing the buck to the user... why should I have to take the time to do this?

  • I changed the settings however Delete files does nothing, old files stay. You should probably manually delete this crap and never use sync for onedrive or whatever causes this problem. 

    the thing is that crap occupies c: drive with expensive ssd memory, i do not mind to keep it on a back up drive

  • If you are still having this issue I was just informed that there's been a solution for this for nearly a year. 

    It's a newer version of OneDrive, a standalone version that merges both the naive OneDrive app and the Office 365 OneDrive for Business after you install it. 

    https://support.office.com/en-us/article/Learn-about-OneDrive-Files-On-Demand-0e6860d3-d9f3-4971-b321-7092438fb38e?ui=en-US&rs=en-US&ad=US

    The new OneDrive features something called Files on Demand that tackles the issue of caching files of entire SharePoint data to the user's hard drive.
