如何使用 File Renamer Batch 批量重命名文件？
How to batch rename files with File Renamer Batch?
- 启动应用，点击「📁 导入文件」或直接拖拽文件到窗口Launch the app and click "📁 Import Files" or drag files into the window
- 在左侧规则面板配置规则（前缀/后缀/替换/正则等），右侧列表实时预览Configure rules in the left panel (prefix/suffix/replace/regex); the right list previews in real time
- 确认无冲突后，点击底部「▶ 执行重命名」Verify no conflicts, then click "▶ Execute Rename"
- 如需恢复，点击工具栏「↩ 撤销」一键还原所有原名To restore, click "↩ Undo" on the toolbar to revert all names
所有规则同时生效，按固定顺序执行：删除（前缀/后缀/范围）→ 查找替换 → 清理（数字/字母/括号）→ 正则 → 大小写 → 添加（前缀/后缀）→ 序号 → 改后缀。All rules apply at once in a fixed order: remove (prefix/suffix/range) → find & replace → clean (digits/letters/brackets) → regex → case → add (prefix/suffix) → sequence → change extension.

如何批量修改文件扩展名？How to batch change the file extension?
方式一：使用「改后缀」输入框
Method 1: the "Extension" field
- 导入文件后，在「普通」标签页的「位置与格式」分组中找到「改后缀」输入框
- Import files, then find the "Extension" box in the "Position & Format" group on the Basic tab
- 输入新扩展名（可带点也可不带点，如
.pdf或pdf；留空保持不变） - Type the new extension with or without the dot, e.g.
.pdforpdf(leave empty to keep) - 右侧列表实时预览，确认无误后执行重命名
- The list previews in real time; execute when it looks right

方式二：使用正则表达式
Method 2: with regex
| 匹配 | Match | 替换 | Replace | 效果 | Result |
|---|---|---|---|---|---|
\.\w+$ | .pdf | readme.txt → readme.pdf | |||
\.jpg$|\.jpeg$ | .png | photo.jpg → photo.png |

如何删除固定文字？How to delete fixed text?
方式一：使用「删前缀/删后缀」输入框
Method 1: the "Rem Prefix/Suffix" boxes
在「文本操作」分组中，「删前缀」输入框删除文件名开头的文字，「删后缀」输入框删除结尾的文字。规则作用于文件名主体（不含扩展名），不区分大小写。
In the "Text Operations" group, "Rem Prefix" strips text from the start of names and "Rem Suffix" strips it from the end. These rules apply to the name only (not the extension) and are case-insensitive.
方式二：使用正则删除任意位置的固定文字
Method 2: delete fixed text anywhere with regex
| 匹配 | Match | 替换 | Replace | 效果 | Result |
|---|---|---|---|---|---|
-copy | (留空) | (empty) | report-copy.pdf → report.pdf | ||
_v\d+ | (留空) | (empty) | report_v3.pdf → report.pdf | ||
\[.*?\] | (留空) | (empty) | [01]song.mp3 → song.mp3 |
「替换」留空表示删除匹配到的内容。Leave "Replace" empty to delete the matched text.
也可以使用「删范围」删除第 N 到第 M 位字符（从第 1 位起算）；只填起始位置时删除到末尾。Or use the "Delete Range" rule to remove characters from position N to M (1-based); leave M empty to delete to the end.

如何添加前缀或后缀？How to add prefix or suffix?
如何给所有文件统一加文字？
How to add text to every file at once?
- 在「文本操作」分组的「前缀」输入框填写要加到开头的文字
- Type text into "Prefix" (Text Operations group) to prepend it
- 在「后缀」输入框填写要加到结尾（扩展名之前）的文字
- Type text into "Suffix" to append it before the extension
- 右侧列表实时预览新文件名
- Watch the live preview on the right
前缀和后缀可同时使用，也可与序号等其它规则叠加。Prefix and suffix work together, and can be combined with other rules like sequence.

如何添加序号？How to add sequence numbers?
如何给文件批量编号？
How to number files in batch?
- 勾选「序号」(Sequence) 复选框启用
- Check the "Sequence" checkbox to enable it
- 「起始」(Start) 默认 1，「补零」(Padding) 默认 4 位（如 0001）
- "Start" defaults to 1 and "Padding" to 4 (e.g. 0001)
- 序号自动加在文件名末尾（扩展名之前），无需选择位置
- Numbers are appended at the end of the name (before the extension) — no position choice needed
序号按列表当前顺序编号：第 1 行 = 起始值，第 2 行 = 起始值+1，依此类推。Files are numbered in list order: row 1 = start value, row 2 = start + 1, and so on.

如何转换大小写？How to change letter case?
如何把文件名改成大写/小写/首字母大写？
How to make filenames upper, lower, or title case?
- 勾选「大小写」(Case) 复选框
- Check the "Case" checkbox
- 在下拉框选择转换方式：全大写、全小写或首字母大写
- Pick a mode from the dropdown: UPPERCASE, lowercase, or Title Case
大小写规则只作用于文件名主体，不会改变扩展名。「首字母大写」会把每个单词的首字母转为大写、其余转为小写。The Case rule affects only the name, never the extension. "Title Case" capitalizes the first letter of each word and lowercases the rest.

如何查找替换文本？How to find and replace text?
如何把文件名中的某段文字换成别的内容？
How to swap one piece of text for another in filenames?
- 在「文本操作」分组的「替换」行，第一个输入框输入要查找的文字
- In the "Replace" row of "Text Operations", type the text to find in the first box
- 在「→」后面的输入框输入替换内容（留空则删除）
- Type the replacement after the "→" (empty = delete)
- 所有匹配项会全部替换，列表实时预览
- Every match is replaced; the list previews live
查找替换区分大小写，替换文件名中的所有匹配项，且只作用于文件名主体（不含扩展名）。Find & replace is case-sensitive, replaces every match, and applies to the name only (not the extension).
如何使用正则表达式？How to use regex?
正则表达式怎么用？
How do I use regex?
切换到「高级」标签页，在「正则与清理」分组中：在「正则」(Pattern) 框输入匹配模式，「替换」(Replace) 框输入替换文本（用 $1 $2 引用分组）。正则作用于完整文件名（含扩展名）。
Switch to the Advanced tab; in the "Regex & Clean" group, enter a pattern in the "Pattern" box and replacement in the "Replace" box (use $1 $2 for groups). Regex works on the full filename including extension.
