Adobe Save As on Mapped Drives is creating .tmp files

Report · Feb 15, 2022

Greetings,

I have verified this issue exists with the following applications: Adobe Acrobat 2017, Adobe Acrobat 2020, Adobe Reader DC.

Issue: When opening a file located on a mapped drive and saving over itself using save as an error is returned and a .tmp file is saved instead of a .pdf.

Steps:

1. Open file on a mapped network drive

2. Choose Save-as and select the same file on the network drive

3. Error returned: "The document could not be saved. Cannot save to this filename. Please save the document with a different name or in a different folder."

4. A file titled something along the lines of: "A972diyz_1dm32eo_fzw.tmp" is then created in the network drive (renaming the file .pdf makes it readable

Troubleshooting:

- Tested mutliple PCs and x3 different versions of Adobe

- If these steps are followed on a local drive or a network location that is not mapped to a letter this issue does not occur and the file saves successfully.

- Network location was added as a "trusted folder path" (Preferences > Security (Enhanced)

- Protected Mode & View are disabled

- Enable Enhanced Security is disabled

- Preferences > Documents > "Automatically save document changes to temporary file every: x minutes" is disabled

- Preferences > Documents > "Save As optimizes for Fast Web View" is disabled

-----

Please advise on possible next steps/fixes.

I had the same issue. Fixed it with:
Go to MENU > PREFERENCES > SECURITY (ENHANCED):
1) UNcheck PROTECTED MODE AT START UP and
2) check ALL FILES under PROTECTED VIEW
3) close app, open a PDF from network drive and edit with a comment and you should see magic happen

This doesn't work for me, and I just lost 2 hours of work to this. Any updates?

Hi @LuArts,

Hope you are doing well. Sorry for your experience with Acrobat.

This sounds very strange and shouldn't be happening.

Would you mind sharing answers to a few questions for better understanding?

1. Do you see this error with a particular file you are trying to work with or a specific file?

2. Have you made sure that the file you are currently working with, is not opened by any other user or on any other system using the same drive? This can cause a conflict when trying to save it.

3. Are write permissions allowed to the folder directory for that drive?

4. Can you try logging in to https://adobe.ly/3XNDL3i, try opening the file there, add a few comments to the document and then save.

5. Please record the entire incident for better understanding and investigation.

Alternatively, you can try going to File Explorer-> click on View-> disable Preview and then try again.

Thanks,

Souvik
