轻巧、快速、占内存少。“查看编辑”与“页面组织”两个工作区各管一摊：读、标、改一份 PDF，或把多个文件拼成一个新 PDF。 Light, fast and easy on memory. Two workspaces, each with one job: read, mark up and edit a PDF in View and edit, or combine many files into a new PDF in Organize pages.
TFolio 只做 PDF 这件事，所以装得下、开得快，也不和别的程序抢内存。 TFolio does one thing, PDFs, so it installs small, opens fast and leaves memory for everything else.
左上角一键切换。处理一份文档时用“查看编辑”，要把几份材料合成一份时用“页面组织”。 Switch from the top-left corner: View and edit for working on one document, Organize pages for combining several into one.
多个文档各占一个标签页，标签页还能拖到新窗口里并排看。Each document gets a tab, and a tab can be dragged into a window of its own.
源文件只读不改；排好页面后点“生成 PDF”，结果在新标签页里打开。Source files are only read, never changed. Arrange the pages, choose Create PDF, and the result opens in a new tab.
装订、外发、归档前最费时的三件事，几下点击就能办好，而且打开就有预览。 The three chores that come before printing, sending or filing, each done in a few clicks with a preview first.
打开“每个文件都从奇数页开始”，TFolio 只在需要的地方补一张空白页，双面打印时每份材料都从正面起头。也可以在任意两页之间手动插入。 Turn on Start every file on an odd page and TFolio adds a blank only where one is needed, so every file begins on a front side when printed double-sided. You can also insert one between any two pages.
输入一行字，每一页同时加上同一个水印。文字大小按页面宽度的比例计算，横版、竖版页面都不会走样。 Type one line and every page gets the same mark. Its size is a share of each page’s width, so portrait and landscape pages both look right.
在页面底部加上“— n —”样式的页码。选择“自动匹配”，奇数页落在右下、偶数页落在左下，按双面装订镜像对称。 Add page numbers in the “— n —” style along the bottom. Choose Automatic and they mirror for double-sided binding: odd pages bottom right, even pages bottom left.
两处小地方，用过就回不去。 Two small things you will miss in any other reader.
PDF 里一个词常被排版拆在两行，TFolio 照样把它算作一处结果；从别处复制来、带着换行的一句话，直接粘进搜索框也能找到。下面这段文字和右图是同一页，试着改搜别的词。 Typesetting often splits a phrase over two lines; TFolio still counts it as one result, and a sentence pasted with its line breaks is found too. The text below is the page on the right. Try another phrase.
8 月 12 日恰好是新月，月亮与太阳同升同落，整夜没有月光。这意味着今年的英仙座流星雨可以在真正的暗夜里观看，肉眼可见的暗弱流星不会再被月光淹没。极大预计出现在 13 日凌晨，届时英仙座已高悬东北天空，每小时可见数十颗乃至上百颗流星。
观看流星雨不需要任何器材，躺椅、保暖衣物与耐心，静候英仙座流星雨的极大便好。让眼睛在黑暗中适应二十分钟，视野里会多出成倍的星星。
New moon falls on August 12, so the Moon rises and setswith the Sun and leaves the whole night dark. That puts thisyear’s Perseid meteor shower under a truly dark sky. Thepeak comes before dawn on the 13th, with up to a hundredmeteors an hour.
Leave the telescope at home: all you need for the Perseidmeteor shower is a reclining chair, warm layers andpatience. Give your eyes twenty minutes in the dark and thesky fills with stars.
页码默认为黑色，落在深色区域时自动改用白色，深浅页面混排也不用逐页调整。这个页面每一节底部的页码，用的也是同样的配色规则。 Numbers print in black and switch to white where they land on a dark area, so mixed light and dark pages need no fixing by hand. The page numbers closing each section of this page follow the same rule.
