Michael's laptop used to be connected to a business LAN and he used mapped drives (O:, P:, etc.) for file saves. He is no longer on the network, and Excel has remembered a P:\Autosave folder destination for Autosave, which is no longer valid. Michael can't pull up the dialog box to change the file location, as he gets an error message every time saying "Can't access directory P:\Autosave". Michael wonders if there is another way to modify his Autosave folder location.
There are several ways you can go about trying to change this. One method is to simply "map" another drive so that the operating system directs any request for drive P: to that drive. There are various methods to do this, such as using the SUBST command. This is an old DOS command that allows a folder (such as C:\MyFolder\MyTemp or some other name) to be "substituted" for a drive letter. Just create the temporary folder and then use the following at the command prompt:
subst P: c:\myfolder\mytemp
You can then access the P: drive (which is really the folder), create the Autosave folder within it, start Excel, make your folder change, and exit Excel. When you want to get rid of the mapping, use the following at the command prompt:
subst P: /d
You can then get rid of the temporary folders you created. Another way to accomplish the same result is to use the NET USE command. Create the temporary folders, as described above, and then share them on your network. (Right-click the folder in a Windows Explorer window and specify it should be shared.) You can then map the drive by using the following at the command line:
net use P: \\ComputerName\ShareName
In this instance you need to replace "ComputerName" with the name of your computer and "ShareName" with the name under which you shared the folder. After the command is successfully used, then all references to P: will redirect to the shared folder. When you are done making the changes you need, use the following command-line command to get rid of the share:
net use P: /delete
You could also try to map a drive by using a USB drive. Use the disk management tools in the Control Panel to change the drive letter of the USB drive to P:. Once this is done you can easily change the Autosave directory in Excel.
If you don't want to take the route of mapping a new drive, you can always try to edit the Registry. Try examining the data in the following key to see if you can locate the folder designation:
You'll need to change the key name depending on your version of Excel; this example is for Excel 2016. All you need to do is change the "16.0" portion to reflect the version you are using. (Look for the AutoRecoverPath key.) If you locate the path to the Autosave folder in the key, simply delete it or change it to point to an available path.
