After using sdscanner, new folders show up as files #11

After using sdscanner, new folders show up as files (4K in size) on the Windows 7 SP1 PC connected to the Android KitKat device via MTP.

What version were you running? I've seen this issue before, which is why 1.11 is supposed to simply ignore a folder with no contents. (I'm just running the normal media scanner API to inform Android about a "new" file/folder, but it does what you describe when run on an empty folder.) Are these folders that actually contain at least one file, in which case it would be something I haven't seen before? Or is the check I'm doing in 1.11 not working in all cases?

From what I've seen, if you've run a version of SD Scanner prior to 1.11, you may still have these folders showing up as files that are still present. A rename or delete dance might fix any given case.

The XDA thread you posted is from before I implemented the workaround.

Definitely version 1.11. Never used a prior version, if that helps.

Folders had other files in them, but no media files. One folder only had only .txt files in it. Another had a .csv file and a sub-folder with a .txt file in it. Both folders were represented as files instead of as folders after running sdscanner. I believe both were created after the phone was last rebooted (and a good chance after Android's media scan was last automatically run).

That's useful to know, and thanks for reporting this. It appears that whether the folder has media files, rather than whether it has files in the first place, is what determines whether the problematic behavior happens.

I'll do some experimenting. It might be the case that if I never call the scanner on directories, this might not happen. But scanning directories might be how deleted files get detected. I'll see if there's a good workaround.

Sounds great. Fortunately, deleting the cache and data for the Media Scanner seems to work effectively to reset it.

I like your different strategies, and I'm guessing one of them will work to solve the problem.

Shouldn't sdscanner work to show all files, even .txt and .csv files?
