Accidental deletion can remove a design file while leaving a preview, shortcut, or older export behind. Before running a scan, identify the actual saved file and the physical disk that held it. This guide explains how to recover FreeCAD FCStd Documents from Windows storage and check whether the recovered work is usable.

Understand the File and Its Dependencies

FCStd is FreeCAD's native document format. It is a container for document structure and geometry, not simply a rendered mesh.

a native FCStd document retains its modeling context, while a geometry export may omit the editable feature tree.

Record the original folder, application version, expected file size, and last useful revision. Keep a list of referenced files or sequence members where relevant. A visible preview or familiar filename does not prove that editable geometry, metadata, or every frame is intact.

If the file still exists but will not open, preserve it and investigate corruption or compatibility separately. An undelete scan does not automatically repair damaged internal structures or recreate changes that were never saved.

Find a Backup and Protect the Source

Check the working folder, FreeCAD backup copies, version control, exported STEP files, Recycle Bin, and synced versions. Keep the native document if available because a geometry export may not preserve the editable design tree.

Check Windows and Application Copies

Open Recycle Bin and compare the original path and deletion date. Check application-managed versions, Windows backups, and the version history of synced folders. When possible, copy a candidate to another physical disk for inspection instead of replacing your only surviving version.

Prepare a Separate Recovery Destination

If no usable backup exists, stop saving, rendering, exporting, or installing software onto the source disk. New writes can overwrite deleted content. SSD TRIM can also make deleted blocks unavailable. Prepare another physical drive with enough space for multiple candidate versions and companion resources.

If the device disconnects repeatedly, makes unusual noises, or reports hardware errors, stop repeated scans and seek specialist assistance. Do not format the source to make it accessible. A local scan cannot recover files that existed only on a remote project server or cloud service.

Recover Local Files with Qiling Deep Data Recovery

Qiling Deep Data Recovery searches Windows-visible local disks and removable storage for lost files. Recovery depends on the remaining file records and data. Do not assume that every specialized design format has a dedicated preview or repair function.

Step 1. Select the Recovery Mode

Run the program from a disk other than the source. Select Fast Scan for recent local deletion, Recycle Bin Scan after emptying the bin, USB/SD Scan for removable storage, or Format Scan after an accidental format. Choose according to the loss event, not the file extension.

Step 2. Select the Source Volume and Click Scan

Identify the volume that contained the original project folder. Check its drive letter and capacity before selecting it, especially if several external disks are connected. Click Scan and allow the scan to complete. Do not select the destination drive merely because it is empty.

Step 3. Review Versions and Related Files

Review names, folders, extensions, sizes, and dates where available. Select several plausible versions rather than discarding alternatives immediately. Include referenced components, resource folders, or sequence files identified earlier. For files with numbered versions, retain the suffixes.

Step 4. Recover to Another Physical Disk

Select the candidates and click Recover. Choose a folder on the prepared destination disk, not another partition of the physical source disk. Wait for the output to finish saving, confirm the files exist, and keep an untouched copy before opening anything in a design application.

Check the Recovered Result

Open a copy in compatible FreeCAD software. Review the model tree, sketches, constraints, recompute status, and final solids. Check any linked documents separately.

If validation fails, compare other recovered versions and backups before editing. Missing references, unsupported versions, or export limitations can resemble corruption. After confirming a working result, back up the file and its dependencies together, with a clear application version and revision label.

Frequently Asked Questions

Can a STEP export replace the native FCStd?

It may preserve useful geometry but not the complete original feature history.

Does an archive test prove the design is intact?

No. A readable container must still be tested for valid geometry and document relationships.

Should I save a repaired or converted copy over the recovered original?

No. Keep the recovered original unchanged and work on duplicates. This preserves alternatives if a conversion, upgrade, or repair drops important information.
