You might get this message for one of these reasons:

• There was a problem with SkyDrive. Try to upload the file again.

• The connection to SkyDrive was lost during the file transfer, or you weren't signed in to SkyDrive. Sign in to SkyDrive with your Microsoft account, and then try to upload the file again.

• You don't have permission to access the file. If the file is on a server, make sure you can open the file, and then try to upload it again. For more info about getting permission to access the file, contact your network administrator.

• You don't have permission to upload the file to the folder that you selected. Select a folder that you have permission to edit, and then try to upload the file again.

Click Replace to replace the existing file, or Keep both to rename the file you're uploading.

Note

• If a file doesn't have an extension, it can't be uploaded to a location that has a folder with the same name.

To upload files to a new folder on SkyDrive, first create the folder, and then upload the files to it. Files that are 0 bytes in size can't be uploaded on SkyDrive.com.

Tip

• If you have the SkyDrive app installed, you can upload folders and empty files by adding them to the SkyDrive folder on your computer.

If you use Internet Explorer 10 or a recent version of other popular web browsers, you can upload files on SkyDrive.com that are up to 2 GB in size. If you use an older web browser, you can't upload files larger than 300 MB on SkyDrive.com.

Tip

• With the SkyDrive desktop app, you can add files up to 2 GB in size to your SkyDrive folder, which gets automatically uploaded to SkyDrive.

You can't upload the file because it doesn't fit in your available storage space. To see space you have remaining or get more storage, go to the Manage storage page on SkyDrive.

The full path (including the file name) is too long. The path must contain fewer than 442 characters. Shorten the name of your file or the name of subfolders in SkyDrive, or select a subfolder that's closer to the top-level folder, and then try to upload the file again.

The file name contains characters that aren't allowed. Change its name so that it doesn’t begin or end with a space, end with a period, or include any of these characters: / \ < > : * " ? |

These names aren't allowed for files or folders: AUX, PRN, NUL, CON, COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT0, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9

The file might have been moved, renamed, or deleted before you tried to upload it. Locate the file, and then try to upload it again.
