Доброго времени суток!

Сегодняшняя заметка будет актуальна для тех пользователей, кто столкнулся с пропажей PDF-файлов на диске, либо с невозможностью их открыть в привычном ридере (см. пример на скриншоте ниже 👇).

Вообще, PDF достаточно надежный формат и менее «капризный» чем тот же DOCX (от MS Word). Однако, причин для подобных «проблем» хватает:

• ошибки при копировании и сохранении документов;
• заражение ПК вирусами (а также некорректная работа антивирусного ПО);
• неисправности жесткого диска и т.д.

Ниже приведу несколько советов и рекомендаций, которые помогут «вынуть» из поврежденного (пропавшего) PDF если не всю информацию, то хотя бы часть (что тоже может сэкономить не мало часов рабочего времени).

И так…

Восстановление PDF-документов: что делать поэтапно

ШАГ 1

Первое, с чем следует определиться — есть ли на диске/флешке в наличии сам документ PDF, или он был удален (например, в следствии форматирования накопителя). Для этого достаточно запустить проводник (сочетание Win+E), разрешить ему видеть скрытые файлы и открыть папку, где должны быть файлы.

Если файлов в нужной папке нет (всё-таки оказалось, что были удалены), то рекомендую следующее:

1. не копировать никакой другой информации на этот диск (новая информация может затереть «пропавшие данные»);
2. не соглашаться с Windows на исправление ошибок (если она будет предлагать это сделать);
3. желательно диск/флешку с пропавшими данными подключить к другому ПК на котором и производить процедуру восстановления (об этом подробно рассказано в моей предыдущей заметке, ссылка ниже 👇).

ШАГ 2

И так, идем далее: файлы PDF в папке есть (либо были восстановлены), но при попытке открыть их — вылетает ошибка: невозможно прочитать данный документ и т.д. и т.п.

В этом случае первым делом обратите внимание на размер самого файла: если он не равен 0÷2 КБ — уже хорошо (значит в нем есть какие-то данные и из него их можно извлечь, см. мой пример ниже 👇).

Примечание: если в вашем случае файл «обнулился» — попробуйте просканировать диск и восстановить удаленный файл с помощью спец. утилит.

На мой скромный взгляд — начать процедуру восстановления данных нужно с Draw (эта программа входит в пакет 👉 Libre Office, кстати, бесплатная!).

После ее запуска, в Draw нужно нажать по меню «Файл/открыть» и выбрать поврежденный PDF — программа задумается на 10-15 сек. и откроет «то, что сможет». В ряде случаев текст остается нетронутым (какие-то картинки, графика, таблички могут «поехать…»).

ШАГ 3

Если предыдущие рекомендации не помогли — пора переходить к услугам спец. онлайн-ресурсов и ПО 👌…

Один из весьма неплохих вариантов в этом случае — сервис от компании Recovery Toolbox (ссылка: https://pdf.recoverytoolbox.com/online/ru/).

Этот инструмент обладает несколькими преимуществами:

• во-первых, он позволяет вытащить данные даже с, казалось бы, самых безнадежных файлов;
• во-вторых, т.к. это онлайн-сервис — вы можете воспользоваться его услугами с любых устройств и ОС: ПК, телефон, планшет и т.д.;
• в-третьих, перед оплатой услуги по восстановлению — вы можете убедиться, что удастся вытащить из документа (покажет превью странички).

Что касается использования: достаточно загрузить файл, указать свою электро-почту, ввести капчу и нажать кнопку «Далее»…

Далее ресурс «задумается» и просканирует ваш документ. Если восстановление пройдет успешно — вы увидите превью своего документа, сможете оплатить его восстановление (10$ за один файл до 1 ГБ) и загрузить к себе на диск. Удобно? В общем-то, да!

*

ШАГ 4

Для тех, у кого повреждено большое количество файлов PDF, либо в документах была очень конфиденциальная информация (которую запрещено куда-либо загружать) — предыдущий ШАГ 3 может не совсем подойти…

В этом случае весьма неплохим вариантом может стать спец. утилита – Recovery Toolbox for PDF (офиц. сайт: https://pdf.recoverytoolbox.com/ru/).

После ее загрузки и установки (она стандартна) — вам останется выбрать исходный файл PDF и «скормить» его. Через некоторое время Recovery Toolbox сообщит вам о том, можно ли из файла еще что-то восстановить…

Отмечу, что утилита работает только в ОС Windows, и полная версия стоит 27 USD (демо-версия — позволит ознакомиться с возможностями перед оплатой). Кстати, у полной версии Recovery Toolbox нет ограничений на количество и размер восстанавливаемых файлов.

PS

На будущее очень рекомендую:

1. делать бэкап (резервные копии) всех важных документов (и лучше, если их будет несколько);
2. если компьютер, с которого вы работаете, постоянно подключен к сети интернет — очень удобно настроить 👉 авто-копирование папки с документами на облачный диск. Таким образом получается автоматический бэкап (никогда не забудете и не будете тратить время на эту операцию).

На сим пока всё. Дополнения по теме — приветствуются!

Удачной работы!
