What is the VER file format?
.ver is a software versioning file - a generic extension applied to files that store software version information. .ver files can be found on installation discs and application folders. The extension is not standardized; content and structure vary entirely by the application that created the file. Most .ver files are plain text containing a version string such as 16.0.1234, though binary variants exist in some applications. .ver files are typically no larger than a few kilobytes.
Well-known applications that use .ver include RealPlayer (version metadata for media plugin update checks) and TurboTax (version and update descriptor files used during software installation). In both cases, files are generated and consumed automatically by the owning application.
Data in .ver files are read by the executable each time it checks for updates or validates its installation. This allows the program to quickly check whether any unwanted changes to the files have been made and whether the installation needs to be updated to match the current version. .ver files should not be deleted or edited manually, as doing so can disrupt an application's update or integrity checks.
Related plain-text configuration formats include .ini files, which serve similar metadata and version-record roles in many Windows applications.
Security & safety
RISK: LOWVER files are version metadata files with no executable content and no known malware usage as a vector. Safe to view in a text editor. The main concern is that modifying a VER file used by an application (e.g., TurboTax or RealPlayer) may confuse the software's update/version checking logic - do not modify.
Format details
in a nutshell- RealPlayer version file - RealNetworks RealPlayer stores version information in .ver files used for update checks and media version tracking.
- Turbo Pascal / Borland version resource - Some compilers and build tools use .ver for version resource scripts (similar to Windows VERSIONINFO .rc files).
Programs that open VER files

TurboTax
Paid TurboTax reads its own VER files internally during installation/update; not designed for manual user access. 
RealPlayer
Freemium If the VER file was created by RealPlayer, the application reads it internally; not designed for manual opening.

Technical details
deep spec| File encoding | Plain text (ASCII/UTF-8) in most cases; binary in some applications - format defined by the creating software |
| Typical size | < 1 KB - most files contain only a version string or small structured record |
| Standardization | Not standardized - structure and content defined entirely by the application that created the file |
| Common content | Version number string (e.g., `16.0.1234`) or key-value metadata; some applications use INI-style or XML structure |
| Container | No standard container; plain-text variants have no binary wrapper |
| Magic bytes | None - no fixed signature; binary layout varies entirely by application |
| MIME type | `application/octet-stream` (binary variants); `text/plain` (text variants) |
| Associated OS | Windows, macOS |
| RealPlayer usage | `.ver` files store version metadata for media plugin update checks |
| TurboTax usage | `.ver` files serve as installation and update version descriptors during software setup |
| File editability | Not intended for manual editing - generated and consumed automatically by the owning application |
| Related format types | `.ini`, `.cfg`, `.xml` - similar key-value or structured metadata roles in Windows applications |
| Released | 1990s (no single origin; used by various applications independently) |
