Troubleshooting
Most messages are one line plus a reason. Here are the ones you are most likely to run into.
“File not found” or “Unsupported file type” at startup
The app was launched with a path that no longer exists, or with an extension outside the four families. Open the file from the Home page instead, and check that the extension is in the supported list.
A .ppt file will not open
Binary PowerPoint files are not supported by the viewer. Save the deck as .pptx in another application and open that copy.
A conversion row shows Failed
- Hover the red status to read the reason for that file.
- Empty files (0 bytes) and Office-looking files that are really something else are rejected before conversion; try opening the file in its own app to confirm it is intact.
- The user-facing summary appears under the batch progress bar; the full detail is appended to the app log (see Files & app data).
- Failures never show a modal dialog during a batch, so the queue keeps going.
“Use OCR” is greyed out
The recognition engine or its language data could not be found. Hover the checkbox: the tooltip names the missing piece. Refilling the tessdata folder next to the app and restarting usually fixes it.
The output file is called “Report (2).pdf”
A file with that name was already in the output folder. The converter never overwrites; it appends a number instead. Pick a different output folder if you want clean names.
Edits disappeared after closing
The app does not autosave and does not ask whether to save when you close or switch files. Watch the · modified marker next to the file name and save before leaving the page.
The DOC or XLS page takes a moment the first time
The editor and its ribbon are built on first use, not at startup — that is what keeps launch fast. A short “Loading editor…” overlay covers the wait; later visits to the same page are immediate.
A browser tab opened when I first ran the app
That was the product page, opened once. The app records that it has been shown and will not open it again on later launches.
Files & app data
Everything the app remembers lives in one folder under your user profile. Nothing is written next to the executable, so the program folder can stay read-only.
| Item | Location | Contains |
|---|---|---|
| App data folder | %APPDATA%\zmapps\documenteditor |
The root for everything below. |
settings.ini |
App data folder | All preferences, including the conversion option and the one-time first-run flag. |
recent.json |
App data folder | The last 50 opened files shown on the Home page. |
crash.log |
App data folder | Details behind conversion failures and unexpected errors. Attach it when reporting a problem. |
temp\ |
App data folder | Scratch space used during conversion and PDF work. |
Deleting the folder resets the app to a fresh state — recent files, settings and the first-run flag all go. Your documents are not stored there and are never affected.
Rating prompt
After a document is opened or saved successfully, the app may occasionally ask you to rate it. Choosing Never show stops the prompt for good; Rate opens the Microsoft Store page. The five stars in that window are decorative — they are not clickable.
Common questions
Can I edit a presentation?
No. PPT is a viewer. Slides can be read, printed and exported to PDF, but not changed or saved. DOC and XLS documents are fully editable.
Is there a dark theme?
Not at the moment. The interface ships in a single light theme, and Settings has no appearance switch.
Can I change the interface language?
The interface is English only. The OCR language list is separate: it controls recognition, not the UI, and grows as you add language files (see OCR for scanned PDFs).
How many documents can be open at once?
One per page. Each page keeps a single document, and opening another file in that page replaces it. You can, however, have a DOC, an XLS, a PPT and a PDF loaded at the same time in their own pages.
Does converting to PDF change my source file?
No. Export and conversion read the document and write a separate file; the original is never rewritten. The same is true for PDF annotation, which always saves a copy.
Can I convert a whole folder at once?
Add the files you need in one pass — select several in the file dialog, or drop a group onto the drop area. Each file becomes a row in the queue.
