Recently, I came across a problem where I had to change the file extension on a bunch of Windows files from no extension to .JPG.最近，我碰到的一個問題，我不得不改變文件擴展對一群Windows文件從不會延長。 JPG格式。 Someone sent me a large number of files, but for some strange reason, they had no file extension, even though they were images!有人給我發了大量的檔案，但為一些奇怪的原因，他們沒有文件擴展名，即使他們的圖片！ Once I added the .JPG extension to the end of the file, I was able to open the images.有一次我補充說。 jpg擴展到去年底，該文件，我是能夠打開的圖像。
There are many other reasons why you may need to rename file extensions , so I’ll show you how you can change them one at a time if you have a small number of files or batch rename file extensions if you have lots of files.還有很多其他的原因，您可能需要重新命名的文件擴展名 ，所以我會告訴您如何您可以更改他們一在一個時間如果您有一個小的數目或批處理文件重新命名的文件擴展名如果您有大量的檔案。
If you’ve gotten an email with an attachment with no file extension, the file may look like this and when you try to open it, may ask you to choose from a list of programs:如果您已經得到了一封電子郵件，附件沒有文件擴展名，該文件可能看起來就像這樣和當您嘗試打開它，可能會要求您選擇從列表中的程序：
Obviously, since there is no file extension for the file, Windows is not able to determine which program should open it.很明顯，因為沒有文件擴展名的文件， Windows是無法確定哪個程序應該打開它。 If you want to change the file extension for the file , you first need to be able to see file extensions in Windows.如果您想改變的文件擴展名的文件 ，您首先需要能夠看到文件擴展名在Windows 。 You can do this by going to My Computer and then going to Tools and Folder Options .你可以做到這一點，去我的電腦，然後去工具和文件夾選項 。

If the file has no extension at all, this step may not be necessary, but I am including it because if you’re trying to CHANGE the file type from one type to another, then you need to do this.如果該文件沒有擴展在所有，這一步可能沒有必要，但我包括資訊科技，因為如果您要改變的文件類型，從一類到另一個，那麼你就需要這樣做。 Now right-click on your file and choose Rename .現在右鍵點擊您的檔案，並選擇重命名 。
Move to the end of the name and type in .XXX or whatever the type is for the file you want it to be, ie .TXT for text files, .XLS for Excel files, etc. Obviously, the file has to have originally been from that program that you are changing the file extension too.移動到年底的名稱和類型在XXX計劃或什麼類型是該文件您希望它，即為。 txt文本文件， 。的xls為Excel文件等，顯然，該文件必須有原本從這個程序，您正在改變文件擴展名。 In my case, the text file was from Excel and I removed the file extension, now I’ll add it back.在我的情況下，文本文件是從Excel ，我刪除的文件擴展名，現在我將它添加回。

We had to change 5879 files from a printmaster “let” xtension to a “sig” xtension我們不得不改變5879檔案從printmaster “讓” xtension一個“ SIG的” xtension
it would only do 39-43 changes at a time,and in the “from” box…once it would change the number of extensions that it did…you would have to change back the origional extension that you were trying to change… ctrl+v is good.它只會39-43變化，在一個時間，並在“從”框…一旦它會改變許多擴展，它… …你將不得不改變回到原來的延長你試圖改變…按Ctrl + V是好的。 Furthermore lets say someone wrote the file name as:此外，讓說，有人寫的檔案名稱為：
j comelately.let (printmaster file) it would confuse the renamer and it would rename it: j comelately.let （ printmaster檔案） ，它會混淆renamer ，它將它重新命名為：
j.let (I’m assuming because of the space between the j.let （我假設，因為之間的空間
j and “comelately”. J和“ comelately ” 。
Further if there is to many periods at the end of the name (ie)jcomelately dr…let (”dr” as an abbreviation for drive then more than one period) it would have difficulties.進一步，如果有很多期在年底的名稱（ IE ）的jcomelately博士…讓（ “博士”作為一個縮寫為驅動器則超過1期）將有困難。

Hi!嗨！ to all expert!所有專家！
I have question in renaming files ie word or excel.我有問題，重命名文件即Word或Excel 。
I usually do like this “right click” the mouse and choose rename… and then type a new file name without adding the extension file ie “.doc” for word and “.xls” for excel.我通常會做這樣的“右鍵點擊”鼠標和選擇重命名…然後鍵入一個新的文件名沒有加入擴展文件，即“ 。文件”字和“ 。的xls ” Excel中。 And yet, everytime I rename a file I am prompted error such as “IF YOU CHANGE A FILE NAME EXTENSION THE FILE MAY BECOME UNUSABLE.然而，每次重命名文件，我提示錯誤，例如： “如果你改變一個文件擴展名的文件有可能成為無法使用。 ARE YOU SURE YOU WANT TO CHANGE IT?” Yes or No!您確定要改變它呢？ “是或否！
I opted YES!我選擇是的！ then it changed different icon on my file(unrecognized icon) and certainly unusable as I could not open the file and says CORRUPT!然後，它改變了不同的圖標在我的文件（無法辨識的圖標） ，當然也無法使用，正如我無法打開該文件說，腐敗！ when I rename it adding the extension file it works!當我將它重新命名，加入擴展文件，它的工程！ ie the new file name in excel is Monthly Report so I have to type Monthly Report.xls - it works this way.即新的檔案名稱在Excel中是月度報告，所以我必須輸入每月report.xls -它這樣做。 BUT previously you don’t need to add the extension file and it will autoadd/fill when you save the file.但以前，您不需要添加擴展名文件，並會autoadd /填補當您保存文件。
