Acts that cause file corruption

· Save files directly to external storage (HDD or USB memory)

· Save files directly to the sync folder of online storage (eg Dropbox or OneDrive)

· PC stops while writing file

→ Do not immediately turn off the PC after CLIP STUDIO PAINT

· Edit the page file directly

 

· (Corrupted configuration file) Malfunction of antivirus software

→ Exclude the CELSYS folder of the document

 

· Computer viruses

· File system malfunction

· Storage failure

· Incident, Accident, Disaster

· Use of old defective version

How to prevent file corruption

· Periodic overwrite save

· Enable "Restore canvas" of CLIP STUDIO PAINT ([Configuration] - [File] - [Restore])

· Enable file history (Windows), time machine (Mac) function

· Use backup software

※ Be sure to perform generation management for backup. It may be overwritten by a damaged file.

 

· Cloud function, use of online storage

· Using antivirus software

How to deal with file corruption

・CLIP STUDIO PAINTのバックアップの確認

[Documents]-[CELSYS]-[CLIPStudioPaintData]-[InitialBackup]

[Documents]-[CELSYS]-[CLIPStudioPaintData]-[DocumentBackup]

[Documents]-[CELSYS]-[CLIPStudioPaintData]-[RecoveryBackup]

· Ask the official support to repair the file

· Use file recovery software

※ Both methods can not always be repaired.

 

· (Damage remains on some layers) Copy and save on a new canvas and save it in another format such as PSD format

※ Because there is a possibility that the situation deteriorates, be sure to save another name.

 

• Due to a problem with CLIP STUDIO PAINT, file corruption may have occurred. Check the support information and try the update.

Recommended backup method

· Cloud function is provided from CELSYS. Since it is necessary to perform synchronization setting with CLIP STUDIO for each work, let's activate it.

 

· (Windows 8 or later) With the file history function, you can easily make backups to external HDD, USB memory, SD card, etc. It is also strongly recommended that you set it up so you can easily recover and open past versions.

 

· You can use the version history with some online storage service such as Dropbox. If you save the file directly to the sync folder, it will cause corruption, so save it in a different location and copy it.

 

· When saving a file for a long time, data may be naturally damaged. It is recommended to save important data in several ways and periodically compare hash values ​​and so on. (It is not suitable for long-term storage of HDD, semiconductor memory, optical disc.)

 

· Some types of HDD (NAS) to be connected by the LAN cable are equipped with a mechanism such as RAID that utilizes multiple HDDs to increase reliability. Prices have also declined, so we recommend that you introduce it if possible. (There is a case that multiple HDDs fail at the same time or data of the device itself is lost. Please be sure to save it in several ways. To use RAID safely, periodic consistency check is necessary .)

 

· (Setting and material) CLIP STUDIO PAINT setting file and material file are saved in the CELSYS folder. Since it is necessary to migrate between the same versions, it may be better to create a backup every time you upgrade. (It seems that it can not be restored 100% though.)

Note such symptoms

· If the file is damaged or disappears, there may be an error in the file system. Please check the problem by running check disk etc.

 

· If you hear an abnormal noise (sound of cotton sound or crackling sound) from the HDD, there is a possibility that abnormality has occurred. It is recommended that you copy the file to another device. Doing check disks, defragmenting, etc. will put a load on it, which may accelerate the failure.

 

· By using HDD self-diagnosis function (S.M.A.R.T.), it may be possible to detect abnormality early. If an abnormal value appears, copy the file to another device. (Since it may suddenly break down from normal condition, overstock is not a thing.)

What to do if you no longer recognize the drive

· Storage will fail for the following reasons

A. File system problem

B. Electronic circuit failure in storage

C. Damage to the recording device

 

a. If you no longer recognize the drive due to a defect in the file system, the file may be recovered with the file recovery software. If the file system of the system drive is damaged and the PC does not start up, you can try recovering the file as external storage by removing the storage from the computer and connecting it to the HDD case. You may be able to recover the file by asking the file restorer.

 

b. It is difficult to recover files by yourself. There are cases where it can be disseminated by asking a restorer.

 

c. It is difficult to recover files by yourself. Although it may be possible to popularize by asking a restorer, it may not be able to spread. Work costs a lot of money.
