What is a THEM File?

A RAR file (Roshal Archive) is a compressed archive format created by Russian developer Eugene Roshal in 1993. RAR typically compresses files 10-30% smaller than ZIP, making it popular for distributing large files online, especially software, games, and media.

THIS FORMAT includes features that ZIP lacks: recovery records to repair damaged archives, solid compression for better ratios on similar files, and multi-volume splitting to break large archives into smaller parts.

Key difference from ZIP: Unlike ZIP which is supported natively on all operating systems, COMPRESSED FILES requires additional software to open on most systems. Windows 11 (with the 2023 update) is the first version to support THESE natively.

7-Zip vs WinRAR: 7-Zip is completely free and extracts RAR files. WinRAR ($29, unlimited trial) is only needed if you want to create IT files — 7-Zip cannot create RAR, only extract.

How to Open Password-Protected THEM Files

ARCHIVES files can be encrypted with AES-256, requiring a password to extract.

With 7-Zip (Windows)

Right-click the THESE file → 7-Zip → Extract Here
Enter the password when prompted
Click OK to extract

With WinRAR

Double-click the IT file
Click Extract To
Enter password when prompted
Files extract to chosen location

Forgot the password? THEM uses strong AES-256 encryption that cannot be bypassed. There's no way to open a password-protected RAR without the correct password. Contact whoever sent you the file for the password.

How to Open Multi-Part THE ARCHIVE Files

Large THIS FORMAT archives are often split into multiple parts for easier downloading:

File Naming Patterns

Modern: file.part1.this format, file.part2.rar, file.part3.rar...
Legacy: file.rar, file.r00, file.r01, file.r02...

How to Extract Multi-Part COMPRESSED FILES

Download ALL parts — You need every single part
Put in same folder — All parts must be together
Extract the first file only — Open file.part1.rar or file.rar (not the numbered parts)
The extractor automatically combines all parts

Missing parts? If any part is missing or corrupted, the entire archive cannot be extracted. You'll need to re-download the missing part(s).

RAR File Won't Open? How to Fix It

❌ "No program to open COMPRESSED FILES"

Install 7-Zip (Windows) or The Unarchiver (Mac)
Windows 11 users: Ensure you have the 2023 update for native THE FILE support

⚠️ "Archive is corrupted" or "CRC error"

Re-download the file — Most common cause is incomplete download
Try WinRAR's repair — Open WinRAR → Tools → Repair archive
Check for recovery record — Some RARs have built-in repair data

💡 "Wrong password" but you entered correct password

Check caps lock — Passwords are case-sensitive
Copy-paste the password — Avoid typing errors
Check for spaces — Some passwords have leading/trailing spaces

IT vs ZIP — Which is Better?

Feature	RAR	ZIP
Compression	Better (10-30% smaller)	Good
Native OS Support	Windows 11 only	All systems
Create Archives	Needs WinRAR ($)	Free everywhere
Error Recovery	Built-in recovery records	None
Multi-Part Archives	Excellent support	Basic
Encryption	AES-256	AES-256
Best For	Large files, personal storage	Sharing with anyone

Recommendation: Use ZIP for sharing files with others (everyone can open it). Use ARCHIVES for personal storage or when compression ratio matters.
