In this articleSymptomsWhen you try to open a file in any Microsoft Office program that's listed in the "Applies to" section, you receive one of the following error messages: Filename is not valid. The file could not be accessed. The path you entered, 'filename', is too long. Enter a shorter path. filename could not be found. Check the spelling of the filename, and verify that the file location is correct. A DDE error has occurred, and a description of the error cannot be displayed because it is too long. If the filename or path is long, try renaming the file or copying it to a different folder. Note This issue occurs when you open a file from a mapped drive, a UNC path, or a URL (web address). CauseThis issue occurs because of a character limit on creating and saving files in Office products. This issue occurs if the path of the file that you open or save meets the following condition:
Note This limit includes the three characters that represent the drive, the characters in folder names, backslash characters between folder names, and the characters in the file name itself. WorkaroundTo work around this issue, try any of the following workarounds. Workaround 1: Reduce the character count
Workaround 2: Manually access, open, and repair
This option repairs the damage to the file, and then opens the file. After you repair the document, workbook, or presentation, it's important to verify that the issue has been resolved successfully. To do this, begin working on the file, and make sure that everything is working as expected. Workaround 3: Change file format and resaveYou might be able to rescue a damaged file by resaving it in a different file format, and then reverting it to the original format. This example uses Word. Step 1: Save the file to another format
Step 2: Resave the file as a Word document
You have to do this only one time to make sure that the document will now function correctly on your device. However, keep in mind that by saving the file as a new document, you're creating a different file. To avoid confusion, name the new file something distinctive, and archive or delete the damaged version. By doing this, you won't accidentally reopen the original file that hasn't been reformatted. Workaround 4: Open unrecognized file formatIf you can rule out file corruption as the culprit, check for file associations and unrecognized file formats. Sometimes, a file won't open on your device because the device that the file was created on used software that your device doesn't have. For example, in Word, you want to view a PDF file that's attached to an email message. However, you don't have a PDF viewer installed. Therefore, your device doesn't know what program to open to view the file. In this case, you can change the format of the file to match a program that you do have installed.

Workaround 5: Clear some disk spaceYou might not be able to open a new file or save a file to your device if you're running out of space on the hard disk. On a full disk, much of the space is being used up by temporary, duplicate, and unnecessary items. The fastest and easiest method to free up space on a hard disk is to use the Disk Cleanup app that's included in Windows.
The following files types are examples of removable items that you might see in the Disk Cleanup list: |
