I tried resetting Trados to default settings, but same error keeps appearing.

Any other help would be much appreciated.

Kind regards,

I know you seem to have discussed the OneDrive thing already, but I do think you should validate what you're doing very carefully and don't assume that your 'local' is local just because it's on your computer.  Check the actual path to your 'local'.  You can get a good explanation just by dropping your error stack into ChatGPT.  For example... and the powershell script idea came from AI as well, and if you can use powershell it might be interesting to have it just as a quick check because it's not always obvious.

===========================================================

This error:

Unable to find the specified file.
System.IO.FileNotFoundException
Source: Sdl.TranslationStudio.Terminology

suggests that Trados Studio was attempting to access a file—most likely a termbase or terminology provider file—but it could not be found at the expected location.

Why OneDrive might be the culprit

If the file (e.g., a .sdltb termbase) is stored in a OneDrive-synchronised folder, a few common OneDrive behaviours can cause this error:

1. Files on Demand (Cloud-Only Files)

OneDrive may mark some files as "online-only" to save disk space. These are visible in File Explorer but not actually present on disk until opened.

• If Trados tries to load a .sdltb file that OneDrive has marked as "cloud-only", it will not be able to access the physical file and will throw a FileNotFoundException.

2. Path Confusion due to Syncing

Sometimes the expected path might have changed:

• If the file was originally on C:\Users\Manuel\OneDrive\... and OneDrive desynchronised or changed folder structure (e.g., after a reinstall or re-login), the path may now be invalid, even though the file still "exists" in your OneDrive cloud account.

3. Permissions or Locking

OneDrive may also occasionally lock or delay availability of files during syncing operations, meaning Trados might try to access the file before it is fully available.

Recommendation

To confirm and fix:

1. Locate the missing termbase file manually – Check if it's marked as "Available when online only" in File Explorer.

2. Right-click and choose "Always keep on this device" – This will force OneDrive to download it locally.

3. Check the actual file path in Trados – Go to Project Settings > Termbases and ensure the termbase path is valid.

4. Avoid placing working files (especially termbases) in OneDrive – Instead, work from a local directory and back up to OneDrive separately if needed.

Would you like help writing a PowerShell script to verify OneDrive status of specific files?

Thank you for the explanation, Paul 

Based on your explanation, I assumed that if I recreated the termbase from a completely new and local file, it should work. Thus, I tried to do the following:

1. I opened a blank spreadsheet in Excel.

2. I copied the contents of a local copy of the XLSX glossary into this new Excel file and saved it on a local folder.

3. Created a SDLTB from this new XLSX file through Glossary Converter (version 6.4.9138.36048).

4. Tried to use it in the Trados Studio project.

5. Same error keeps appearing.

I do not know how to use PowerShell. Would that help to fix the issue or am I doing something wrong?

Kind regards,

Manuel

Can you share the full path to your local folder?

Hi.

Of course, it is C:\Users\Manuel\Documents\NO ME BORRES!!!\sdltb\[ClientName]
(I cannot disclose the name of the client, but it is just one word with no special characters).

If it helps, I tried creating the SDLTB in the Desktop and Trados Studio still shows the same error.

Kind regards,

Can you open the termbase in MultiTerm without any problems?

I just opened it and yes, I can, and everythings shows properly. The only problem seems to be in Trados Studio.

Manuel Rubio Máñez 

ok - in that case before we engage support can you do a reset.  That often cleans out all sorts of "unresolvable" issues.  

To do this just close Trados Studio and then delete these folders:

%appdata%\Trados\Trados Studio\Studio18\

%appdata%\Trados\Trados Studio\18\

You will lose your plugins, and also your settings, but your projects and other resources will remain untouched. Putting the plugins back is trivial via the integrated appstore.

If you can't find these folders then you need to unhide your hidden files/folders:

Then restart Trados Studio and see if that helped.

I had to restart the computer because it seems that, even after closing Trados Studio, some program/service was using those folders or its contents and could not be deleted. After the restart, I deleted them... and unfortunately, the error keeps on showing.
