File Path Character Limit
Any directory in your Teams files that has a directory path of approximately 200 characters will need to be shortened by either changing folder names, moving the folders, or reorganizing the folder structure entirely.
If this is not done, the file will not be able to be opened within any Office 365 application.
Once the file path is shortened, you will be able to open the file again within Office 365
To check the characters for the directory open up the directory you would like to check and click in the directory path. Copy the path and paste it in the box below. See picture for reference.
Keep in mind that the file name also counts towards the total character count and even if the directory is around 200 characters, your file might not be able to be opened if it’s name is too long.
