Question 1

Why does drag and drop fail silently when moving a file with the same name in Lap file manager?

Accepted Answer

This is a bug in Lap 0.3.2 and earlier: dragging a file into a folder that already contains a file with the same name fails silently without the duplicate-name conflict dialog. Update to Lap 0.3.3 or later. The fix makes drag and drop show the same conflict dialog as the 'Move to folder' command, letting you skip the file, keep both, or replace it, with an option to apply the choice to all conflicts in a batch. Transfer failures now also display an error message instead of failing silently, and the conflict dialog supports the Esc key (same as clicking close, which skips the file).

Question 2

Which RAW file formats are supported (CR2, CR3, NEF, ARW, RAF, DNG)?

Accepted Answer

RAW support was added in v0.1.11. Supported formats: Canon (cr2, cr3, crw), Nikon (nef, nrw), Sony (arw, srf, sr2), Fujifilm (raf), Panasonic (rw2), Olympus/OM System (orf), Pentax (pef), Adobe/generic (dng), Samsung (srw), Leica (rwl), Minolta/Konica Minolta (mrw), Hasselblad (3fr), Leaf/Phase One (mos), Kodak (dcr, kdc), Epson (erf), Mamiya (mef), generic raw, and legacy mdc. Update to v0.1.11 or later to index these files. Note: Sigma x3f is NOT supported because the LibRaw pipeline returns FileUnsupported for sampled X3F files, causing indexing to fail.

Question 3

Why do thumbnails flicker or disappear when hovering the mouse over them on Linux with an NVIDIA GPU?

Accepted Answer

This is an NVIDIA driver compatibility issue. Debian 13.7's default repository ships the older NVIDIA 550 driver, which causes thumbnails to appear and disappear on hover. Fix: download and install the latest NVIDIA driver (version 595 or newer) directly from nvidia.com instead of using the distribution repository driver. After updating the driver, thumbnails render correctly.

Question 4

How to add or test a custom language translation in Lap?

Accepted Answer

Lap stores each UI language as a separate JSON file in `src-vite/src/locales` on GitHub. To create a new translation: 1) Download the English JSON file as a template. 2) Translate the values into your language. 3) To test locally on Windows, replace the contents of any existing language JSON file with your translated content. Note that officially adding a new language requires a small code change to register it, so submit your translation file via a pull request and the maintainer will add it to Lap's language options.

Question 5

Why do cached thumbnails disappear in Lap when the external drive is disconnected, and how to browse photos offline?

Accepted Answer

This is a known bug in Lap (v27.0): cached 256px thumbnails display correctly in **All Files** when the external drive is disconnected, but selecting a greyed-out Album located on the unavailable drive causes all cached thumbnails to disappear from All Files too.

**Workaround to use Lap as an offline photo catalog:**
1. Disconnect the external drive.
2. Quit and restart Lap.
3. Stay in **All Files** — do NOT select any Album/folder from the disconnected drive (they appear greyed out).

All cached thumbnails (~24,000 in the reporter's case) remain browsable this way. If you accidentally click an unavailable Album and thumbnails vanish, simply quit and restart Lap to restore them in All Files.

**Setup tip:** Keep Lap's database and thumbnails on your Mac's internal drive and the full-resolution originals on the external drive. You only need to reconnect the drive when accessing original full-resolution files.
