Hi Carlos,
Welcome to Box community!
Please note, Box Drive does locally cache files that you have opened. Box Drive's cache size limit is based on your free disk space (50% of available space) and has a maximum limit of 25 GB. If you reach this limit, Box Drive begins removing files, starting with those files that have gone the longest without your accessing them. Also, if a cached file has a new version created on Box, Box Drive discards the locally cached version.
Cache information and behavior
- When you add a file to Box Drive, Box copies the file into the Drive cache folder, which creates a local copy of the file. So, when adding larger files to Drive, be sure to provide enough local storage for the local copy of the file.
- When you open a file in your Box folder, Box Drive downloads the file to the cache folder (folder location above) to open the file.
- Box Drive deletes a cached file:
- When the file cache has not been modified for the past 30 days -- that is, no modifications are made to the cached file.
- You can reduce this duration. (To adjust the cache duration, please see steps below.)
- If the same file on Box is updated with a new version on Box.
- In this case, Box Drive's locally cached file is no longer up to date, and Box deletes it. Box Drive does not re-download the file until you re-open the file via your Box folder.
- If you reach the cache size limit. In this case, Box removes first those cached files that have gone the longest without being modified.
- When you log out of Box Drive.
- Box Drive deletes a cached file that is available offline if you log out of Box Drive.
- Box Drive's maximum cache size limit is set to 50% of your available local disk space or 25 GB, whichever is smaller. Box Drive requires at least 1 GB of free space to function properly. (To do this, please see steps below.)
- Files marked for offline access do not count against this limit. You can fill up your hard drive until you have 2 GB of remaining space.
- Box Drive cannot delete a cached online-only file in the following cases (in these cases it's possible the limit can be exceeded):
- the online-only file has changes that never uploaded to Box
- another program is preventing Box Drive from deleting the online-only file.
Do not use or modify files in the cache folder. Doing so may result in unexpected behavior. Always access your content through the Box folder.
- Box Drive cache is not encrypted and is not removed automatically when you uninstall the Box Drive program. After you uninstall the program you can delete the cache folder manually.
- Logging out of Box Drive deletes all cached files (including offline files and offline preferences) and all log files.
- It is not possible to completely disable Box Drive's caching functionality.
