在这个时代，您可以找到许多承诺帮助您恢复已删除文件的应用程序。有很多选项很好，但问题是，哪些程序擅长恢复已删除的文件？他们谁(Which)兑现了他们的承诺？为了找出答案，我们测试了这个利基市场中一些最受欢迎的应用程序，所有这些应用程序都免费供个人使用。让我们看看我们发现了什么：
注意：(NOTE:)在本文中，我们测试了三个真正免费的文件恢复软件：Recuva vs. PhotoRec vs. IObit Undelete。我们还想进行Recuva 与 EaseUS(Recuva vs. EaseUS)的比较，但不幸的是，后者并不是真正免费的应用程序，因为它只允许您恢复最多 2 GB 的丢失数据。
我们如何测试免费的文件恢复软件
我们拿了一个USB记忆棒并对其进行了格式化，以确保上面没有任何东西。然后我们在上面复制了各种各样的文件：
- 30 个文档（16 个 .xlsx、7 个 .pdf 和 7 个 .docx 文件），总大小为 3.30 MB
- 30 个音乐文件（.mp3 文件），总大小为 198 MB
- 30 张图片（.jpg 文件），总大小为 90.10 MB
- 15 个视频（.avi 文件），总大小为 5.78 GB
我们总共有 105 个文件，大小为 6.07 GB。
我们用于测试恢复软件的文件
接下来，我们使用Shift + Delete键永久删除了所有文件(deleted all the files)，并在记忆棒上添加了 20 个新文件（jpeg 图像，总大小为 57.40 MB）。我们这样做是为了了解当某些已删除的文件可能被其他文件部分覆盖时，每个程序在恢复文件方面的表现如何。由于删除的文件位于USB记忆棒上，我们将文件恢复到计算机的固态驱动器。
然后是时候测试我们计划审查的数据恢复应用程序了。我们选择了您在下面看到的程序，因为此时它们是利基市场中最受欢迎的。我们还想将此评论仅限于免费应用程序，没有任何限制，因为大多数人并不热衷于花钱购买他们可能只使用一次或两次的应用程序。
1. Recuva
Recuva从一个向导开始，它可以帮助您选择要扫描的位置和文件类型。该应用程序在 0.09 秒内完成了扫描，在我们删除的 105 个文件中找到了 85 个。它在 5 分 26 秒内恢复了它们，并且所有 85 个恢复的文件都完好无损。不幸的是，我们最初拥有的 30 个.mp3音乐文件中有 20 个无法恢复。(.mp3)
Recuva使用快速扫描恢复已删除的文件
第二次运行Recuva，使用深度扫描选项可以得到更好的结果。尽管深度扫描本身花费的时间要长得多（31 分 3 秒），但Recuva发现了 144 个可恢复文件。这比我们在USB记忆棒上复制的文件数量还要多：Recuva在格式化之前设法检测到在记忆棒上发现的 59 个附加图像文件。但是，它在第一次（快速）扫描时没有恢复的 20 个 .mp3 文件仍然未被检测到且无法恢复。恢复时间与我们记录的第一个相似：5 分 24 秒。

2.TestDisk PhotoRec
TestDisk PhotoRec是一款出色的数据恢复应用。该软件是开源的，这意味着它完全免费供任何人使用。没有经验(Inexperienced)的用户可能会从一开始就拒绝它，因为它没有被宣传为具有图形用户界面。但是，如果您仔细查看下载的 zip 文件，您会发现一个名为qphotorec_win.exe 的应用程序，(qphotorec_win.exe,)它只不过是带有图形界面的PhotoRec工具。(PhotoRec)🙂
TestDisk PhotoRec有一个带有图形界面的工具
看看PhotoRec与Recuva，PhotoRec处理丢失文件的恢复过程与Recuva或其他类似软件不同。选择要扫描的驱动器和恢复文件的位置后，它会立即检索它可以检索的所有内容。
在我们的测试中，它从 105 个被删除的文件中找到并救出了 85 个文件。它设法在 25 分 56 秒内完成。那是相当长的时间，不幸的是，这个应用程序没有像Recuva这样的深度扫描功能。

3. IObit 取消删除
IObit Undelete提供了一个易于使用的界面，看起来也不错。文件恢复过程可以简单到选择丢失的文件类型，选择找到它们的驱动器，然后开始搜索。此应用程序不包含许多高级设置，但这意味着您无需阅读用户手册即可直接恢复文件。
IObit Undelete恢复的已删除文件
(IObit Undelete)在我们删除的 105 个文件中，IObit Undelete总共恢复了 85 个文件。扫描时间为 14 秒，而总文件恢复时间为 5 分 18 秒。不幸的是，IObit Undelete不提供类似于Recuva的深度扫描功能。

最佳(Best)文件恢复软件：Recuva vs. TestDisk PhotoRec vs. IObit Undelete？
我们创建了一个表格，其中汇总了我们的发现。看一下以获得一个很好的概述：
免费文件恢复软件比较
总结一切，很明显，明显的赢家是Recuva。查看恢复的已删除文件的数量，Recuva、TestDisk PhotoRec和IObit Undelete都设法检索到相同数量的文件。但是，在运行深度扫描时，Recuva甚至可以恢复在我们格式化之前在USB记忆棒上找到的一些文件。这比其他两个应用程序管理的结果更好。
我们还注意到在扫描速度和恢复已删除文件所需的时间方面存在显着差异。从任何角度来看， IObit Undelete 与 TestDisk 与 Recuva(IObit Undelete vs. TestDisk vs. Recuva)的较量似乎都被后者赢得了。在我们测试的应用程序中，没有一个比Recuva更好。
您认为哪个是最好的文件恢复软件？
我们希望这种比较有助于您做出明智的选择。如果您有任何问题，请随时发表评论。此外，如果您使用过任何这些文件恢复应用程序，请在下面分享您的经验。它肯定会帮助别人。
Best free file recovery software: Recuva vs. the competition -
In this day and age, you can find many apps that promise to help you recover deleted files. It is great to hаve lotѕ of options, but the question is, which programs are good at recovering deleted fіles? Which of them dеliver on their promise? To find out, we tested some of the most popular applications in this niche, аll of which are free for pеrsonal use. Let's see what we discoverеd:
NOTE: In this article, we test three truly free file recovery software: Recuva vs. PhotoRec vs. IObit Undelete. We also wanted to do a Recuva vs. EaseUS comparison, but, unfortunately, the latter is not a genuinely free app, as it only allows you to recover up to 2 GB of lost data.
How we tested the free file recovery software
We took a USB memory stick and formatted it to make sure there was nothing left on it. Then we copied a wide range of files on it:
- 30 documents (16 .xlsx, 7 .pdf, and 7 .docx files) with a total size of 3.30 MB
- 30 music files (.mp3 files) with a total size of 198 MB
- 30 images (.jpg files) with a total size of 90.10 MB
- 15 videos (.avi files) with a total size of 5.78 GB
In total, we had 105 files with a size of 6.07 GB.
The files we used for testing recovery software
Next, we deleted all the files permanently, using the Shift + Delete keys, and added 20 new files (jpeg images, 57.40 MB total size) on the memory stick. We did that to see how good each program would be at recovering files when there are chances of having some deleted files partially overwritten by others. Since the deleted files were on a USB memory stick, we recovered the files to our computer's solid-state drive.
Then it was time to test the data recovery apps we planned to review. We chose the programs you see below because, at this moment, they are the most popular in the niche. We also wanted to restrict this review only to free apps, without any limitations, because most people are not keen on spending money on apps they might only use once or twice.
1. Recuva
Recuva starts with a wizard, which helps you choose the location and file types you are about to scan. The application made the scan in 0.09 seconds and found 85 out of the 105 files we deleted. It recovered them in 5 minutes and 26 seconds, and all of the 85 recovered files were intact. Unfortunately, twenty out of the thirty .mp3 music files we had initially were unrecoverable.

Running Recuva a second time, using the deep scan option gave better results. Although the deep scan itself took much longer (31 minutes and 3 seconds), Recuva identified 144 recoverable files. That’s more than the number of files we copied on the USB memory stick: Recuva managed to detect 59 additional image files that were found on the stick before formatting it. However, the twenty .mp3 files that it didn’t recover on the first (fast) scan were still undetected and unrecoverable. The recovery time was similar to the first one we recorded: 5 minutes and 24 seconds.

2. TestDisk PhotoRec
TestDisk PhotoRec is an excellent data recovery app. The software is open-source, meaning that it is entirely free for anyone to use. Inexperienced users might be tempted to dismiss it right from the start because it’s not advertised as having a graphical user interface. However, if you look closely inside the zip file you download, you’re going to find an app called qphotorec_win.exe, which is nothing else but the PhotoRec tool with a graphical interface. 🙂
TestDisk PhotoRec has a tool with graphical interface
Looking at PhotoRec vs. Recuva, PhotoRec handles the lost files recovery process differently from Recuva or other similar software. After selecting the drive that you want to scan and the recovered files’ location, it immediately retrieves everything it can.
In our test, it found and rescued 85 files from the 105 deleted files. It managed to do it in 25 minutes and 56 seconds. That is quite a long time, and, unfortunately, this app doesn’t have a deep-scan feature like Recuva.

3. IObit Undelete
IObit Undelete offers an easy-to-use interface that also looks good. The file recovery process can be as simple as selecting what type of files you lost, choosing the drive on which they were found, and then starting the search. This app does not include many advanced settings, but that means you can jump right into getting your files back without having to read user manuals.
Deleted files recovered by IObit Undelete
IObit Undelete recovered a total of 85 files out of the 105 files that we’ve deleted. The scan time was 14 seconds, while the total file recovery time was 5 minutes 18 seconds. Unfortunately, IObit Undelete doesn’t offer an in-depth scan feature similar to Recuva.

Best file recovery software: Recuva vs. TestDisk PhotoRec vs. IObit Undelete?
We created a table with a summary of our findings. Take a look to get a good overview:
Free file recovery software comparison
Summing everything up, it is evident that the clear winner is Recuva. Looking at the number of deleted files that were recovered, both Recuva, TestDisk PhotoRec, and IObit Undelete managed to retrieve the same number of files. However, when running a deep scan, Recuva managed to recover even some files that were found on the USB memory stick before we formatted it. That’s a better result than what the other two apps managed.
We also noticed meaningful differences regarding the scanning speed and the time it took to recover the deleted files. From any perspective you look at, it seems that the contest of IObit Undelete vs. TestDisk vs. Recuva was won by the latter. Out of the apps we tested, none was better than Recuva.
