LM Studio Models Missing After an Update: Check the Model Directory First
TL;DR:
If LM Studio models appear missing after an app update, run the lms ls command to verify the active model directory before attempting data recovery because the app may just be checking the wrong location.
● If your GGUF files still exist outside the expected ~/.lmstudio/models/publisher/model/ structure, use lms import
● If the files were actually deleted from the disk, prioritize redownloading them using lms get unless the specific quantization is custom, unhosted, or too costly to download.
● If using Recoverit File Recovery for permanently deleted local models, immediately stop writing to the drive to prevent SSD TRIM data loss, and treat the scan as a best-effort search since GGUF is not explicitly confirmed as a recognized file signature.

In this LM Studio update case on Reddit, the user said downloaded models appeared to be gone after updating the app and could not tell whether the files had been moved or deleted. Do not start with a recovery scan. First determine whether LM Studio is simply looking at a different model directory or whether the model files are actually absent from disk.
Confirm What LM Studio Can Still See on Disk
- Step 1
Run
lms ls. LM Studio says this command lists models available on disk and reflects the current models directory configured in the app. - Step 2
Inspect the current model directory. LM Studio documents the expected structure as
~/.lmstudio/models/publisher/model/model-file.gguffor imported GGUF models. - Step 3
If the original model file still exists outside the active directory, use
lms import <path/to/model.gguf>to bring it back into LM Studio instead of trying to undelete it.
These checks come from LM Studio's current model-listing and model-import documentation.
If the File Is Really Gone, Decide Whether Redownloading Is Enough
If the same model and quantization are still available online, LM Studio's lms get command can download a specific model or quant again. This is preferable to file recovery when the missing file is replaceable.
If the missing model was custom, no longer hosted, or too costly to replace over a slow connection, stop writing to the drive before trying any deleted-file scan. This matters especially on an SSD, where TRIM may make deleted model data unrecoverable.
When Local File Recovery Becomes Relevant
If you confirm the model file itself was deleted from a stable, readable drive and no intact copy exists, Recoverit File Recovery can scan the local storage for deleted data. Public Recoverit documentation does not explicitly confirm GGUF as a recognized file signature, so use the scan as a best-effort search, recover candidates to another drive, and verify that the model loads before changing the original storage.
