Frequently Asked Questions

A .mat file is a material asset used by Unity scenes and prefabs. Check version control and project backups before scanning. The material's .meta file identifies it to references by GUID.

Find Existing Copies

Search the original project folder by name and extension, including the Recycle Bin and other project locations. Check the application's recovery or backup area and any repository or team version history. A missing entry in a recent-files list does not prove that the file was deleted.

Keep matching .meta, shaders, textures, and Assets folder structure. Do not let the editor generate a new asset in the original project while you are searching.

Prepare for Recovery

Identify the Windows-visible physical drive that held the missing Unity material (.mat). Stop saving new project versions, downloads, or exports to that drive. Prepare another physical disk for recovered results. If the source has hardware faults or disconnects repeatedly, avoid stressing it with repeated scans and seek specialist help.

Confirm whether the missing item was actually saved locally. A deleted-file scanner cannot retrieve a cloud-only file from a remote service or recreate unsaved work. Use the service's version history or the application's own recovery feature first when those are available.

Scan the Original Drive with Qiling Deep Data Recovery

Qiling Deep Data Recovery can search local Windows-visible storage for deleted files. It cannot guarantee recovery if the blocks were overwritten or cleared by SSD TRIM. Keep the scan and recovery output off the source when possible.

Step 1. Select a Scan Mode

Open the program and match the mode to the loss: Fast Scan for a recent local deletion, Recycle Bin Scan after emptying the bin, USB/SD Scan for a removable source, or Format Scan if the original partition was formatted. The mode depends on the event, not the project file extension.

Step 2. Choose the Source Drive

Select the disk or partition that actually stored the file. Confirm its drive letter and capacity, especially if several external disks are connected. Do not choose the separate destination disk as the source.

Step 3. Compare Candidate Versions

When results appear, search by project name and extension if available. Compare location, size, timestamp, and related files. Keep more than one plausible copy. If the source is healthy but the first pass misses the file, try the deeper scan option before changing the disk.

Step 4. Recover to Another Physical Disk

Select likely candidates, click Recover, and save them to a different physical drive. Keep the recovered originals unchanged and test copies in a separate project workspace; do not overwrite a working backup.

Check the Restored Project

Open a copied Unity project, inspect the recovered material's shader, texture slots, colors, and the objects that use it.

If the file opens but content is missing, compare other candidates, application backups, and linked assets. A correct filename or successful preview is not proof that every referenced item survived. Back up the verified project and its dependencies.

Frequently Asked Questions

Will a texture image restore a MAT material?

No. It does not contain the material settings and references.

Why do surfaces remain pink?

Check shader compatibility and missing material or texture references.

Where should I keep a recovered project?

Save the result on a different physical drive until it has been checked. Then make a separate backup of the complete project folder.
