一款轻量级脚本工具，可将任意文件（支持拖拽多个文件/文件夹）转换为BAT批处理可识别的Base64字符串格式。该工具输出的原始字符串可直接嵌入批处理脚本使用，无需额外处理；仅当需要将字符串打印至A4纸张进行纸质化保存时，需手动替换Base64中0/O、1/l/I等易混淆字符（避免OCR识别错误）。
BAT脚本支持直接打印输出内容，且转换后的BAT字符串可完整还原任意原文件，由此实现了用纸保存任意文件的独特方式。打印保存时推荐优先选择小文件（如短字符串、TXT、DOCX、PPTX等），这类文件转换后的字符串长度适配单张A4纸，不仅节省纸张，更能大幅提升OCR识别的准确率。
A lightweight script tool that converts any file (supports dragging multiple files/folders) into a Base64 string format recognizable by BAT batch processing. The original string output by the tool can be directly embedded into batch scripts for use without additional processing; only when it is necessary to print the string to A4 paper for paper-based storage, it is required to manually replace easily confused characters (such as 0/O, 1/l/I) in Base64 (to avoid OCR recognition errors).
BAT scripts support direct printing of output content, and the converted BAT strings can fully restore any original file, thus realizing a unique way of saving any file with paper. For paper storage via printing, it is recommended to prioritize small files (such as short strings, TXT, DOCX, PPTX, etc.), as the converted string length of such files fits a single A4 sheet, which not only saves paper but also greatly improves the accuracy of OCR recognition.

| l（小写字母L） | ㊑ | 避免与数字1/大写字母I混淆 |
| I（大写字母I） | ㊒ | 避免与数字1/小写字母l混淆 |
| +（加号） | ㊣ | 避免与数字7/字母t混淆 |
| /（斜杠） | ㊤ | 避免与反斜杠/数字1混淆 |
| Original Base64 Character | Recommended Replacement | Replacement Note |
|---|---|---|
| 0 (Number zero) | ㊀ | Avoid confusion with letter O |
| O (Uppercase letter O) | ㊊ | Avoid confusion with number 0 |
| 1 (Number one) | ㊁ | Avoid confusion with lowercase l/uppercase I |
| l (Lowercase letter L) | ㊑ | Avoid confusion with number 1/uppercase I |
| I (Uppercase letter I) | ㊒ | Avoid confusion with number 1/lowercase l |
| + (Plus sign) | ㊣ | Avoid confusion with number 7/letter t |
| / (Slash) | ㊤ | Avoid confusion with backslash/number 1 |

场景2：打印到A4纸保存（需手动替换字符） | Scenario 2: Print to A4 Paper for Storage (Need Manual Character Replacement)
-
按「场景1」步骤生成包含原始Base64字符串的
.bat文件； -
打开
.bat文件，对照「易混淆字符替换清单」手动替换所有易混淆字符； -
利用BAT直接打印功能，将替换后的字符串完整打印至A4纸张（优先选择小文件，单张纸即可保存）；
-
如需还原文件：
- 步骤1：通过OCR识别纸张上的字符串；
- 步骤2：对照替换清单反向还原字符（如㊀→0、㊁→1）；
- 步骤3：将还原后的Base64字符串解码，即可恢复原文件。
-
Generate a
.batfile containing the original Base64 string according to the steps in "Scenario 1"; -
Open the
.batfile and manually replace all easily confused characters with reference to the "Base64 Easily Confused Characters Replacement List"; -
Use the direct printing function of BAT to print the replaced string completely to A4 paper (prioritize small files that can be saved on a single sheet);
-
To restore the file:
- Step 1: Recognize the string on the paper via OCR;
- Step 2: Reverse restore the characters with reference to the replacement list (e.g., ㊀→0, ㊁→1);
- Step 3: Decode the restored Base64 string to recover the original file.
- 转换大文件（＞100MB）时可能耗时较长，请耐心等待；
- Converting large files (>100MB) may take a long time, please wait patiently;
- 文件夹转换会递归处理内部所有文件，生成整合后的BAT字符串；
