I have noticed that if you use the remote desktop connection, a file called bcache22 (a bitmap cache file I believe) is placed in the Temp folder of main memory - this can be very large; I just deleted one that was 8mb in size, so clearly this is chewing up a lot of memory. A soft reset does not clear this folder either so it has to be manually deleted.
Not sure if this happened on WM5 roms, but it could explain a lot of the memory loss that some people are experiencing - I would summise that if you use remote desktop (terminal services client) you will see memory loss and if you don't, you won't, hence the intermittent nature of the memory loss.

Dear all:
I have study the private directory of WINCE. I am confused with the memory mapping schema. For example, the two virtual memory 88000000 and 0xa8000000 will mapping to the same physical address. The first one is used to allocate to application,the other is used to allocate to DMA buffer.But in a CPU with virtual cache, the two virtual addresses map to the same phycial address will arise synonym problem or called "alias".For example, the data in the physical address could be updated by DMA buffer and the same address could be used by another
application and reference to the wrong data. How the OS avoid this problem when the memory is overlap? Does anyone knows the reason of the memory mapping in Windows CE? Or any books or web sites I can get the imformation of the CE kernel? Thanks a lot!
the virtual addresses from 8000000-9fffffff have the 'cachable' and 'bufferable' bits set in the TLB, a0000000-bfffffff have them turned off.
IO addresses should be accessed not through the cache, that is why
you see accesses to for example the serial port to go through a803000
and accesses to ram usually via 8c00000
I think it avoids it because it knows what memory it is using, hand probably has some mutexes setup to regulate access.
userspace processes should not try to directly access physical ram, although they can, which is quite unusual for OSes these days.
I made a dump of the TLB here
what puzzels me about it is that I don't see the mapping of the lower process addresses here.
Hi,
I have been told that there is a registry setting to prevent applications being unloaded from a WM5/6 device.
Can anyone tell me what it is?
I want to install a personal fw but don't want the users to unload this when my back is turned and opening up our network...
Many thanks,
Sam.
You can remove a program from the 'uninstall' list via registry (sorry don't remember the key) but this won't stop someone from simply deleting the files.
As for stopping an up from running - there is no such key. If the program has no active or visible windows it will not show in the regular task manager, but if a user knows enough he can easily delete if from autostart or turn it off using a 3rd party app manager.
But there is one thing I don't quite understand about your question:
You want to put a firewall on the phones of people in your company / organization so that when they connect to your network they won't jeopardize it?
Don't you need a firewall on the network side for this?
Note that WM devices (unlike XP etc) have virtually no server components so unless your users install a harmful app there is nothing for the intruder to connect to. (No file sharing, no remote desktop etc.)
Hi guy’s
I wondering if some one of you know about a program called "ifile" or something like that
I don’t need to say the name of the phone where roun this software but is not from Microsoft (clear enough right?)
So, I would like to know if there exists the same program for HTC HD or something like it.
I talking about a program that makes possible to transfer files from the pc to the Blackstone BY WLAN and so on so far.
I mean that you just need to write the IP address in your pc at the explorer and that’s it
Thank very much
every addon file explorer like total commander (free) and resco explorer (commercial) have builtin lan support
it works much like windows' "map network drive" function and is very good, i myself i use it alot
you can even use, instead of ip addresses, the network names of the computers or browse through the whole network.
i MIGHT be wrong but it seems to me that even the default winmo file explorer can do such thing provided you install file explorer extensions (search on this forum you will eventually find them out and read about those)
some ideas
Hi. There are some options i can think of from the top of my head.
1
share a folder on your pc, access it from your device with your favorite browser (Total Commander).
2
read in about getting activesync going over wlan
3
mail stuff to your self and check it on your other device
4
try to find a web or ftp server for ppc
5
there might be some remote control software (you know, to control your ppc from pc, or take screensnaps etc) that is able to transfer files. I know there is a lot of remote progs available.
6
There is software available to browse ms networks from ppc, maybe there is some that puts your pcc right in there.
I´ll add more if I think of any.
Use Google.
Several apps are taking too long to load. Namely, MS Office including Notes. I seem to recall a registry mod that addressed the issue and it had to do with networked folders or a large memory card (searched many forums, many ways but could not find it again). It appears the problem may be with the 8GB microsd card installed and these programs scanning memory before opening. When the card is removed, the programs operate quickly. Previously, I had a 2GB card and did not notice any issues. I would prefer a default folder being opened, so I can browse for files manually. Is this possible?
Tilt2 w/ HTC updated ROM (ver. 2.10.502.4)
Office 2010
SPB Mobile Shell
iSS Essentials
8GB microSD class 4
I have not had this problem might want to check your memory and make sure other apps are not hogging it
I have connected a usb-c enclosure with NVMe to my new P6Pro. Everything looks okay until I try to transfer certain files (and/or transfer a bunch of data). One that I keep having issues with is a TitaniumBackup file, about 200-300mb.
All my other Pixels (3XL, 4XL) transfer the file just fine. Transferring between a PC & the P6P works fine (both ADB & file share push from the PC).
At first I suspected that phone doesn't provide enough power to the OTG, but it's happening very consistently with certain files, which should take ~1sec to transfer at USB3 speeds...
Wondering if it's my device or a more common issue.
Interesting. I don't have any external NVMe adapters. I do use an "old" USB-C hub that includes a Micro SD slot, and I regularly copy my music from that to my P6P's internal storage, but none of these files are likely that big (it's funny calling anything less than many GB big, but I guess all music, even my preferred format FLAC files, are still reasonably sized). I transfer a total of ~400 GB of music. I don't have the same issue but very different enough circumstances, so I'm not revealing any very helpful information.
Seems like this has to do with .nomedia file handling
0-byte .nomedia is apparently invalid now -- and if encountered, something bad (like this) happens

Hmmm, I use .nomedia files extensively in all of my music's deep folder's structure, but I create them with an app that does it all at once and haven't copied those files to the source locations on my computer hard drive or the duplicate copy on Micro SD card. I'll set a reminder to run some experiments when I'm in front of the computer tomorrow and report back.
Of course, it could be specific to NVMe drives, or particular types/technology of NVMe drives, and I won't be able to confirm either of those through an adapter, anyway.
Okay, did some digging. First, back when I used to manually create .nomedia files (or use an old app to do so), they were of course zero-byte (empty) files. This app Nomedia, although slow, does work for me, and apparently creates the files with various small byte-lengths - the contents of which are merely the text of the path it put them in.
I also learned that they only seem to be necessary at a root level to completely exclude everything underneath it. I didn't remember that was the case. So I only have six .nomedia files in my 400GB+ of music files folder structure, and I'll just keep in mind never to create my own, or if I do, to always have something in the file so it's zero-byte length. I can only assume the developer for that app knew that zero-byte .nomedia files could cause some problems.
