File and folder locations

8 min readAppendices

The installation folder, the settings and log files of Studio and Live, project files, the .veri folder, backups, folders under the user account, and what needs to be backed up.

This topic is the complete list of the places on the computer where FabyaVision writes and reads. The paths refer to the default installation; if you chose a custom installation folder, read it in place of C:\Program Files (x86)\Fabyatek\FabyaVision. The details of each program are described in the relevant topic.

Installation folder

The default location is C:\Program Files (x86)\Fabyatek\FabyaVision on 64-bit Windows and C:\Program Files\Fabyatek\FabyaVision on 32-bit Windows; if installed for a single user only (/CURRENTUSER), it is %LOCALAPPDATA%\Programs\Fabyatek\FabyaVision. The programs are in sibling folders (Installation):

FabyaVision\
  fabyavision.ico, unins000.exe  simge ve kaldırma programı
  fabyavision.lic                deneme lisansı (yalnız deneme kurulumunda)
  Studio\
    FabyaVision_Studio.exe
    studio_ayarlar.json          Studio'nun kendi ayarları
    logs\                        Studio günlüğü

  Ornekler\
    Demo_Projesi.fvs             örnek proje kopyası (yalnız örnek bileşeniyle)

The program files (.exe, wwwroot) are writable only by the administrator; do not modify them. The wwwroot\kurulu_diller.js file of each program holds the languages selected during setup.
Setup opens the locations that the programs write to with write permission for users: Studio\logs, Live\logs, Convert\logs, Live\Projeler, studio_ayarlar.json, live_ayarlar.json and the license folder (below). If these locations cannot be written to, the settings are not persisted and no log is kept.
An update does not touch the settings files or the Live\Projeler folder.

Studio

Unless stated otherwise, paths are relative to the Studio\ folder.

File or folder	Content
`studio_ayarlar.json`	Theme, language, interface scale, author, default project folder, automatic backup interval, 3D view and placement model, last opened project, list of recent projects (up to 10), last upload folder. If the file is missing or corrupt, it opens with the defaults. Settings
`..\ai\`	AI package: the model file and runtime components. It is not included in the setup and is downloaded separately; `FabyaVision_AI_<sürüm>.exe` places it in the `ai` folder in the installation folder. It can also be in the Studio folder, or its location can be set in `studio_ayarlar.json` (AI Assistant overview).
`logs\StudioAI_yyyyMMdd_HHmmss.log`	Log of the local model server.
`logs\Studio_yyyyMMdd.log`	One text file per day. Files older than 30 days are deleted when Studio starts. Help›Open log folder opens this folder. Log files
`%LOCALAPPDATA%\FabyaVision_Studio\WebView2\`	User data of the WebView2 component that renders the interface. Panel widths, column orders and Toolbox group states are stored here. It is not edited by hand; if it is deleted, this layout information is reset.
`Belgeler\FabyaVision Projeleri\`	The location suggested by the New Project window; used when Studio settings in Project folder is empty. The Open and Save as windows, on the other hand, start in the folder of the most recently opened project.

Project files

A project is a single file: <Ad>.fvs. The file is JSON written as UTF-8 text. Saving creates side files (Project files, Revision and backup):

File	When	What it is used for
`<Ad>.fvs.tmp`	While saving	It is written here first and then put in place of the actual file; if the power fails, no half-written file remains. It is normally not visible.
`<Ad>.fvs.bak`	On every Save	The previous version of the file. It is a single file and is renewed at every save.
`Yedek\<Ad>_<yyyy-MM-dd_HHmm>.fvs` (next to the project file)	Save backup copy…, automatic backup	A maximum of 20 backups are kept.
`Yedek\` (in the target folder of the upload to Live)	When Overwrite is chosen while the same project exists at the target	The old version is kept; a maximum of 10. Uploading the project to Live
`<Ad>.veri\`	While Live is running	Data that the project generates in Live. See below.

Live

Unless stated otherwise, paths are relative to the Live\ folder.

File or folder	Content
`live_ayarlar.json`	The last opened project, the project folder, automatic start, the screenshot folder. If the file is missing or corrupt, it runs with safe defaults.
`logs\Live_yyyyMMdd.log`	The Live program log; files older than 30 days are deleted at startup.
`Projeler\`	The default folder scanned by the project selection screen. If it cannot be written to, `%LOCALAPPDATA%\FabyaVision\Projeler` is used. If Sample project was selected during setup, `Projeler\Demo_Projesi\Demo_Projesi.fvl` is also located here.
`%LOCALAPPDATA%\FabyaVision_Live\WebView2\`	The WebView2 user data of Live. It is not edited by hand.
`Belgeler\FabyaVision_Live\Ekran Görüntüleri\`	The PNG files of the Save screenshot action key (the folder set in `EkranGoruntuKlasoru` in `live_ayarlar.json`, if it is filled in).

Data belonging to the project: <Ad>.veri

Live writes the <Ad>.veri folder next to the project file; uploading from Studio does not touch it. Its main subfolders are:

depo\: persistent tag values, recipe records, task status, the preferences of this computer (istasyon.json) and connection passwords (baglanti_sifreleri.json).
gunluk\: monthly event, alarm, archive, report, recipe transfer, notification and performance report records (olay_yyyyMM.log, alarm_yyyyMM.log, bildirim_yyyyMM.log …).
raporlar\: the PDF and Excel files of performance reports (raporlar\<yyyy>\<MM>\).

File-by-file details, deletion rules, and backup: Files and folders of Live.

Locations under the user account

These are located under %LOCALAPPDATA%\FabyaVision\ and depend on the Windows user. If you open the program with a different Windows account, that account creates its own copy.

Location	Content
`uzak.anahtar`	The key that signs the remote monitoring session cookies. It is encrypted in a way tied to the Windows account; if it is deleted, the sessions in the browser become invalid and a new login is requested.
`OpcUa\pki\own\`	The OPC UA certificate of this computer (`certs\.der`) and its private key (`private\.pfx`).
`OpcUa\pki\trusted\`, `issuer\`, `rejected\`	Manually trusted server and certificate authority certificates; intermediate certificate authorities; rejected server certificates (for review).
`OpcUa\sunucular\`	The certificate of each OPC UA server, saved at the first connection (`adres_port.der`).
`OpcUa\sunucu-pki\`	Certificate stores of the OPC UA server of Live itself: `own\`, `trusted\`, `issuer\`, `rejected\`. They are separate from the client certificate of the driver (OPC UA server).
`Bildirim\`	E-mail password, SMS key, modem APN password and SIM PIN (`eposta.bin`, `sms.bin`, `apn.bin`, `pin.bin`). They are encrypted in a way tied to this computer; if copied to another computer they cannot be read and must be entered again there (Notification center).
`Projeler\`	Live's fallback project folder when the program folder cannot be written to.

License files

License-related files are outside the program folder; uninstalling FabyaVision does not delete them (License and activation).

Location	Content
`%ProgramData%\Fabyatek\FabyaVision\Lisanslar\`	The full-version license files of this computer (`.fvk`; the older `.lisans` files are also read). The license page and the License Manager write here; the setup creates the folder writable for all users.
`Lisanslar\lisans.idx` (hidden file)	Signed states received by the online license check from the FabyaVision server (active, revoked, moved).
`<USB>:\FabyaVision\Lisanslar\`	Licenses bound to a USB drive.
`%LOCALAPPDATA%\Fabyatek\FabyaVision\cache\lic.idx` and `HKCU\Software\Fabyatek\FabyaVision\Lisans` (`Durum` value)	Copies of the same statuses in this Windows account. When they are read, all of them are merged; deleting one does not change the status.
`%LOCALAPPDATA%\Fabyatek\FabyaVision\cache\act.idx`	Trial version only: the online activation of this Windows account (Trial version).

Locations you choose

The programs write the following files to the location you choose; they have no separate default folder: report PDF, CSV and Excel exports, tag Excel and CSV transfers, script files. A save-file dialog opens each time to choose the location.

Items to back up

What	Cause
Project files (`.fvs`) and `Yedek` folders	The design itself. On the Studio computer and in `Live\Projeler`.
`<Ad>.veri` folders	Live data: persistent values, recipe records, alarm, event, archive and report history, performance report files. No automatic backup contains them.
`live_ayarlar.json`	Which project and folder are being used.
`studio_ayarlar.json`	Optional: theme, author and recent projects.

What happens on uninstall

The logs folders and the two settings files are deleted.
If Live\Projeler is not empty, it is not deleted, and its path is reported in a message when the uninstallation is finished. If the sample project was installed, its copy Demo_Projesi.fvl is also regarded as user data and remains; this is why you see the message.
The folders under %LOCALAPPDATA% and the projects and screenshots under Belgeler are left untouched. The license files (%ProgramData%\Fabyatek\FabyaVision\Lisanslar) and the SQL Server installed by the setup also remain.
