Microsoft Word file names changing to .~WRD[4 Digits] and then deleting themselves

[vrt785]

I have multiple word documents saved on an external hard drive. After upgrading to Microsoft Word for Mac Version 16.55 (21111400) and upgrading my mac to Mac OS Catalina Version 10.15.7, I started noticing issues when trying to save Word documents on my external hard drive. When I try to hit Command+Save (and sometimes before I even try to save), the file name changes to .~WRD followed by 4 random digits. Then I get an error message stating "Additional permissions are required to access the following files: /Volumes/G-DRIVE mobile USB-C/.Te...ing Saved by Word 170)/.~WRD3512." When I hit the "Select" button, I am then taken to a menu that says "Please select the file .~WRD3512." But no file appears and I cant select "Grant Access." So I click cancel.

When I try to select File > Save, I get the message:

This document’s file has been changed by another application since you opened or saved it.

The changes made by the other application will be lost if you save. Save anyway?

If I select save, I get taken back to the Grant File Access page described above. So I cant save the document. Then, when I try to close out the document, it gives me the prompt:

Do you want to save the changes made to the document “.~WRD3512 [Compatibility Mode]”?

Your changes will be lost if you don't save them.

In the case of the lost document, since I couldn't save, I had to click "Don't Save." Then, I saw that neither the original document was in the folder nor was the renamed document. So my document completely disappeared, despite years of working on it and saving it multiple times. Since it was on an external hard drive, Time Machine didn't back it up and I have no idea where it is. Im absolutely mortified and stressed as this was a very long and important document. I simply cannot understand or believe how this happened. Has anyone had a similar problem to this? Do you know how I can recover the file? Does anyone know why this happened / what is happening?

Any info would be greatly appreciated

NEVER save a Word document directly to any external drive. Catastrophic corruption of the document is a very likely consequence. ALWAYS move the document to the local drive and open it from that location to edit it and then save back to the local drive. After saving and closing the file, you can move it to the external drive if you want a copy of it on that drive.

I experience the same issue when I save files located in folders connected to Google Drive (Version: 54.0.3.0). I hope anyone would share experience on how to solve this problem. Thanks a lot.

I suspect that the problem here is that Google Drive isn't supported as a saving location in Word/Office.

@vrt785 

I have spent many hours with Msoft Tech Support about this problem.

We pursued:

1) changing the location of docs folder

2) reinstalling Word

3) reinstalling Office

4) my purchasing a whole other Office package

5) changing the file name

6) disconnecting external drives

7) copying and pasting the content into a new document

8) viewing raw data

9) recreating the document from scratch

10) reformatting the drive and installing a new OS

The problem recurred regardless of all this. Tis still repeatedly happening while attempting to save over an open document after adding a certain amount of text into the document. 

I have been working around the problem by navigating back to the doc folder, typing in the original file name and replacing the old document.

Most frustrating was losing transcripts from a 24 hour long (3-8 hr day) seminar. The only way to get a partial recovery of the data was to purchase a data recovery software which only recovered about 50% of the document.

What is the path the the folder where you are saving the files? Is it a folder on the C: Drive or another drive installed IN your computer. Is the folder being synchronized with any external destination (drive, OneDrive, Dropbox, etc.)

@Doug_Robbins_Word_MVP 

Path is a fast 12 tb external USB 3 drive that works fine for every other application including real time writing of multitrack audio and video in Final Cut, Protools, Media Composer, etc....

@Music_Prof It doesn't matter how fast the interface is.  NEVER work on a Word document when it is located on any form of external\removable device and NEVER save a Word document directly to such a device!

So... reading the comments on this post, isn't there a solution for this problem?

Working locally is not a solution, as it happens with Sharepoint files...
