Ios: Shows wrong cache usage (Settings/Advanced/Clear Cache)

[doomi]

It shows a wrong cache usage in
Settings/Advanced/Clear Cache:

used 279.01 GB

I have an 128GB iPhone 6s.
Nextcloud app is using 62MB as of iOS settings/Storage usage.

@doomi Which app version are you using?

[doomi]

I always use the current version. already updated once or twice since filing the report.
right now it's Nextcloud for iOS 2.18.2.00001

currently the cache usage shows 279.94GB :)

I have the same problem, although not as dramatic. iOS says the app is using ~400MB and the app says it is using ~3GB. Clearing the cache does not help. I even logged out of my accounts and deleted the app.

[doomi]

It’s getting worse, iOS is also showing the wrong size.

[doomi]

There seems to be two issues: cache size and iOS storage usage. I finally could clear the cache and for now it looks ok (10MB). I will report on that in the future.

I think I found the cause of the second issue. I configured Google drive as external storage and there‘s about 270GB used. my Nextcloud usage is about 30GB. So together it‘s those 300GB iOS is reporting.

[doomi]

I disabled the external storage plugin on the server and reinstalled nextcloud on my iPhone, now it‘s showing the correct usage again!
I had to delete and reinstall the iPhone app. clearing cache and iPhone reboot didnot work.

Btw: my iPhone backup in iTunes was also 300gb in size! I will see if it‘s smaller now...

[doomi]

for a year now I didn't find out why my iPhone backup with iTunes was about 300GB in size, but I only have an iPhone with 128GB! it took about 2 days to complete each time!
now that I disabled external storage it not only shows the correct size in the iPhone settings, but the backup is now the correct size too!

so the iPhone backup downloads and includes the external storage!!!
guys, this is a big issue, not only a wrong usage display problem!

[rakekniven]

@doomi Please open seperate issue regarding your last post.

[doomi]

@rakekniven ok, I will open a new issue. But I‘m pretty sure if this bug is fixed (by excluding external storage) it will also fix the backup issue.

[rakekniven]

@doomi Thanks for filing new issue. So we close this?

[doomi]

@rakekniven No!! (Why?!)

[rakekniven]

You are right, misread one of your comments.

[doomi]

this bug is still annoying me! I got again the error in iTunes while backing up the iPhone: "itunes could not back up the iphone because not enough free space is available on this computer"
there was 200GB free space on my Macbook and the iPhone is only 128GB.
the Nextcloud app showed 1TB cache size, which is clearly impossible.
after deleting the cache in the app, the iTunes backup works again!
so it also propagates the wrong cache size to iTunes.

and why does Nextcloud not use the proper cache folders on iOS? if it would use the correct folders, then iTunes would not try to backup the cache. and iOS could automatically purge the cache folder by itself, too.

I Remove it, the calculate is too imprecise

Just for the records:

[doomi]

Removing the display of the size does not resolve the problem of using the wrong cache directories.
Is there a reason to not use the official cache directory defined by Apple standards? Then iOS could automatically delete the cache if the device gets full and iTunes would not backup the cache, neither.
