How can we improve Excel for Windows (Desktop Application)?

Increase the 218 character filename length limit to open files in excel

Excel can't open files with full path lengths greater than 218 characters as documented in This is still a problem in Office 2016. It seems crazy that Excel can't open a valid file that the filesystem allows. People have been complaining about this since Office 2000. The thread below has over 11 thousand views and there are plenty others. Please fix this.

        We are gradually implementing the use of SharePoint Online libraries in the entire organization and certain departments heavily use Excel. The 218 character filename length limit is the most prominient problem we have encountered this far. Please prioritize this fix.

        To quote someone below: "Better yet why hasn't Microsoft replied to this thread yet?" A reply would be very much appreciated!

        I had been putting up with renaming filenames at work whenever the path had become too long when working with files in our network. Eventually however, I came to the point where I could not open a file whatsoever. What I mean is, even when the Excel filename was 1 character long, it would not open. On top of the obvious things wrong with this issue that has been explained by many others a multitude of times, it's ridiculous that an Excel file can actually exist in a folder with a separate filename character limit, but isn't able to be opened because it has a separate, archaic character limit.

        Is it really that hard to change the data type from char to literally any other data type? This is day 1 programming class stuff. You should be ashamed. After using Excel for 10+ years, you are forcing me to use another program. Are you happy now?

        Yup, still an issue to this day, 3 years after the initial request. Come on Microsoft, this is a biggie.

        Sorry, but it cannot be true that this issue is still present.
        Looks like all the programming effort went in the new (and, by the way, quite annoying) optical redesign and additional (even more annoying) online functions.

        It seems that Microsoft is using a byte to hold the length of a full filename! (Something left over from DOS 2? You see Bill, you didn't need to copy everything DR did - there was room for improvement.) A 20+-year-old problem? Even for Microsoft with its ubiquitous breathtaking arrogance, that's quite a long wait for a fix.

        This is particularly severe with Sharepoint where it's nigh on impossible to work out just how long a 'full filename' actually is.

        Agreed with everyone here. Just adding another comment to this list. Hoping against hope it will be fixed.

        I was just hit by the same "feature" aka bug and I can only join the bandwagon and pray Microsoft folks to do something about this!

        i tested it in the 2019 preview it is still the same problem... hey microsoft please!!!!!!

      • P commented  ·   ·  Flag as inappropriate

        This is an absolute pain - in a corporate environment with sharepoint servers individual users loose control over path lengths. So I need to store the doc locally and loose all online collaboration capabilities ?!?!?

        I have two main issues with this error:

        1. I recently upgraded to Windows 10 and now can't access many of my existing documents.

        2. I am trying to save an Excel file that only drill down two levels of sub-folders.
        It is ridiculous that this is a problem only in Excel but other Office programmes work perfectly.

        This issue has been in Excel for a while, but Office 365 really makes it more visible. When you save a file to your Office 365 account, every space in the file becomes 3 characters (%20), and the entire path is essentially prepended with So you can have ~100 extra characters added to your file's path without changing a thing! Please fix this!

        This post was created two months after Office 2016 was released and it is still an issue? LibreOffice doesn't seem to have this issue. When the group creating the NTFS file system, and REFS I would imagine as well, said that they were expanding the file system naming format to allow a total of ~32k characters long back before at least 2008 why didn't the office group follow suit and support long file names? To know that the problem has been around for the better part of a decade and not be addressed seems concerning to me.

        Better yet why hasn't Microsoft replied to this thread yet?

        I found a work around until @Microsoft brings Excel into the 21st century.

        You can mount a drive that points to a folder. This will get rid of the unnecessary long path coming out of a synced OneDrive folder.

        instead of
        C:\Users\JohnDoe\CompagnyX\Name of the share point or one drive\Projects

        You have to use the windows command "subst"


        They do no mention how to implement it, but a simple batch file located in the windows StartUp folder takes care of the rest.
