Where Does IrfanView Store Settings INI File?
IrfanView stores all settings in a single INI file named i_view32.ini (32-bit) or i_view64.ini (64-bit). Location depends on install option and is shown in Properties.
Last updated
IrfanView uses one INI file for settings. File name must match bitness: i_view32.ini for 32-bit, i_view64.ini for 64-bit.
Exact folder is chosen during install and displayed in Options > Properties > Start/Exit. Copying that file to the same location on another PC migrates settings.
Where IrfanView stores this, by platform
C:\Users\<username>\AppData\Roaming\IrfanView\i_view64.ini
Default when installer option stores INI in user AppData folder. 32-bit builds use i_view32.ini in same folder. Same as %AppData%\IrfanView\i_view64.ini. Replace <username> with Windows user name. Preferred for standard installs without admin write issues.
C:\Program Files\IrfanView\i_view64.ini
Used for central, portable or older installs. 32-bit path is often C:\Program Files (x86)\IrfanView\i_view32.ini. Writing here may need admin rights. Custom path can be forced with command line /ini="Folder" or INI_Folder setting.
Frequently asked questions
How do I find my active INI path?
Open IrfanView > Options > Properties > Start/Exit tab. The INI file path and name are listed there. Copy that exact file for backup.
Why are settings not saving?
The INI file or folder is read only, the install folder needs admin rights, or a cleaner tool reverts it. Reinstall with INI in AppData, remove read only flag, or exclude IrfanView folder from cleaner tools. Use matching file name for bitness when copying between PCs.
