This file is one of two essential "key" files (along with locked-secret.bin) required by TagMo to decrypt and write Amiibo data. Without these keys, the app cannot interact with Amiibo .bin dumps. Common Tasks & Troubleshooting
If you are trying to "draft" or set up these files for the first time, follow these steps:
Importing Keys: Open TagMo, tap the three dots (menu) in the top-right corner, and select Load key(s) file... then select unfixed-info.bin and locked-secret.bin.
File Detection Issues: If the app doesn't see your files, ensure they are placed in a reachable directory like Downloads or the dedicated TagMo folder on your device's internal storage.
Amiibo Dumps: Once the keys are loaded, you can use the Load Tag button to select your specific Amiibo character files. Related Technical Terms
If your query is about a different type of "draft" or "bin" file, you might be referring to:
IETF Internet-Drafts: Technical documents in progress, often named with draft- prefixes (e.g., draft-ietf-httpbis...).
Matomo Tag Manager: Uses a Draft version label to indicate you are working on a container that hasn't been published yet.
unfixed-info.bin from ReappearingYou cannot stop AMD from writing this file without breaking driver functionality. However, if you simply hate seeing it, you have two options: unfixed-info.bin
Absolutely delete. If you uninstalled your AMD drivers or built a PC that never had them, but the file remains, it is useless clutter.
| Aspect | Assessment | |--------|------------| | Safety | ✅ Safe (when from AMD) | | Necessity | ❌ Not required for daily operation | | Deletable | ✅ Yes (post-installation) | | Recreatable | ✅ Yes (on next AMD update) | | Malware risk | ⚠️ Low, but always verify origin |
Final Take: unfixed-info.bin is the digital equivalent of a mechanic's sticky note—scribbled during engine work, useful for the process, but irrelevant once the job is done. It is not a virus, not a critical system file, and not something to lose sleep over. If it annoys you, delete it. If you never see it, ignore it.
The real lesson here is broader: In an age of ransomware and zero-day exploits, fear of the unknown is rational. But not every odd-looking binary is a backdoor. Sometimes, unfixed-info.bin is just AMD's awkward way of saying, "We saw your custom overclock. We didn't touch it. Here's a receipt."
Stay informed, verify signatures, and always keep your drivers—and your skepticism—up to date.

unfixed-info.bin is one of two essential encryption "keys" (the other being locked-secret.bin
) required to decrypt and write Amiibo data to NFC tags using applications like This file is one of two essential "key"
. Without these keys, the software cannot verify or write the proprietary Amiibo data. How to Use unfixed-info.bin
To use this file for creating custom Amiibos, follow these general steps: miffycs/Animal-Crossing-Amiibo - GitHub
In the context of creating custom clones, unfixed-info.bin is a critical decryption "key" file required by software like TagMo or AmiiBoss to process Amiibo data. What is unfixed-info.bin?
This file contains the necessary cryptographic data to handle the unfixed portion of an Amiibo's internal storage.
Purpose: While the Amiibo character data itself is "fixed" (read-only), the "unfixed" section contains information that changes, such as in-game save data, levels, or stats.
The "Key" Duo: It is almost always used in tandem with another file, locked-secret.bin, which handles the static character identification.
Retail Key: Many modern apps now use a single file called key_retail.bin, which is simply a combination of both the unfixed and locked keys. How to Use It
To program a blank NTAG215 tag (the only compatible tag type) into an Amiibo, you must "import" these keys into your writing app. DIY Amiibos - Cruise Chaser BLASSTY How to Prevent unfixed-info
Without additional context (such as which software, game, or device generated it), here is the general technical meaning and common scenarios where this type of file appears.
Game modding / ROM hacking (most common)
unfixed-info.bin sometimes stores unencrypted or uncompressed data that will later be "fixed" (encrypted/compressed) when rebuilding the ROM.Firmware or embedded system update
unfixed-info.bin as a staging file before applying patches or checksums.Corrupted or partial download
Malware or cracked software
