TWRP requires an unlocked bootloader. Unlocking that bootloader (via fastboot or an exploit like adb reboot bootloader on older builds) triggered a factory reset. All user data was wiped. Many first-timers learned this the hard way.
That looks like a TWRP recovery package filename for an Android device. Quick points:
If you want next steps, pick one:
Which would you like?
File Name: t310.twrp.3.1.0-1.tar.md5
Software: Team Win Recovery Project (TWRP)
Version: 3.1.0-1
Target Device: Samsung Galaxy Tab E 8.0" (SM-T310) t310.twrp.3.1.0-1.tar.md5
If you download t310.twrp.3.1.0-1.tar.md5 and try to open it with WinRAR or 7-Zip, you’ll likely see a single file: recovery.img. But the .md5 suffix changes how you handle it.
How it works:
Never rename or modify this file. Even changing one byte will break the MD5 check, forcing you to either re-download or manually strip the .md5 extension (not recommended for beginners).
