When you overwrite a computer file or document, you put new information in the same place as the old information, and the old information is gone. People say this when they save a document under the same name, copy one file on top of another, or tell a programme to replace what is already stored.

When you overwrite a computer file or document當你覆寫（overwrite）一個電腦檔案或文件時, you put new information in the same place as the old information你把新資料放進舊資料原來的位置, and而 the old information is gone舊資料就消失了。People say this大家會這樣說 when they save a document under the same name當他們用同一個檔名存檔, copy one file on top of another把一個檔案複製蓋過另一個, or tell a programme to replace what is already stored或叫程式取代已經存好的東西。

Though actually, at work people stretch it to any time new data takes the old data’s seat — a cell in a spreadsheet, a line in a database, a track on a tape.

Though actually不過其實，at work在職場上 people stretch it to any time new data takes the old data's seat大家會把這個字用得更廣，只要新資料佔了舊資料的位置就算──a cell in a spreadsheet試算表裡的一格, a line in a database資料庫裡的一行, a track on a tape錄音帶上的一軌。

The word carries a small warning: once something is overwritten, you usually cannot get the earlier version back unless you made a copy first. It is computer talk. You would not use it for handwriting on paper; that is just writing over something, or crossing it out.

The word carries a small warning這個字帶著一點小警告：once something is overwritten一旦東西被覆寫了, you usually cannot get the earlier version back你通常拿不回原本的版本 unless you made a copy first除非你先備份過。It is它是 computer talk電腦用語。You would not use it for handwriting on paper你不會拿它來說紙上的手寫字；that is just那只是 writing over something蓋寫在東西上面, or crossing it out或畫掉而已。
