Check your qdata.qph file. Perhaps it got lost.
Try to find a backup of qdata.qph from ver 16 and compare the file sizes.
My quicken data is stored in \users\me\documents\quicken\qdata.*
I have 7 files for my quicken data set; .HCX, .IDX, .QDF, .QEL, .QIN, .QPH & .QTX.
.QDF is the main data file (largest) with most transactions and .QPH contains all historical prices. Perhaps you only copied 1 file, rather than 7 ?
There are two quite different places PP 2016 backup data can be found. One is easy to restore, the other is more difficult. It is, of course, assumed the necessary files still exist.
The 1st location is where you backup files to when PP periodically prompts you. Restoring a backup file is straightforward.
The 2nd location is where PP creates temporary automatic backups which it cycles through. The number of temporary backups kept is set in Edit => Preferences => Program => Backup => Maximum Number of Backup Copies. (I have set this to the maximum of 9.) Temporary backup version file names are suffixed with a backup number. If you installed PP 2018 into a different folder from PP 2016, the temporary backups may still be available. This procedure only needs to be invoked if there is no permanent backup available.
Note that data can be restored into new directory if you care to do so. This can compartmentalise the old data and the newly restored data. I recommend this be done.
A new data folder can be sected from File => Restore Backup File >= Restore Backup... => Local Backup => Restore => Select the disk drive and path where you want to restore the file to:. A new folder can be created from Browse => Make New Folder.
The above suggestions only deal with restoring earlier backups. They do not address the issue of "corrupted" files. Only undertake suggested procedures if you feel confident in doing so. And always backup, backup, backup.
PP DOES KEEP ROLLING BACKUPS in a "BACKUP" folder. They can be used for data recovery, however, accessing them is not straightforward. Rolling backup files are also overwritten each time an Account File is opened and closed. The oldest backup is removed and a new one is created, which means they are short lived.
I appreciate the above may be a little obscure and of very little assistance to you. Hopefully, it does at least provide some context for the problem at hand.
It seems that there are two options available. The 1st is to restore an earlier backup of your PP 2016 data, assuming one exists. The 2nd is to rebuild your account data manually as John has suggested.
Restoring a backup file of working data should be the most straightforward option, however, nothing is guaranteed with Reckon PP.
The 1st step is to determine if a usable backup exists. Local backup files can have one of two formats. (If backups are kept online, I cannot provide further assistance as I have no experience with them.)
The 1st type of backup is a single compressed archive file with the suffix .rkn. An example of a compressed archive file name is:
[As an aside, a .rkn file is actually a ZIP file and can be renamed with a .ZIP suffix and be opened with WinZIP or 7z software. The .rkn file contains the same 6 files identified below in a compressed format.]
The 2nd type of backup consists of 6 files. An example is shown below. Note that individual files might also include a date.
It may be possible to find the location of backups by opening Reckon PP and going to File => Backup => Local Backup. The field "Select the disk drive and path to the backup folder" may contain the address of the last backup. If the directory is not shown there, you may be able find it by searching for .rkn or .QDF files. Remember to distinguish between backup files and active files with may have the same name.
If you can find a valid backup of PP 2016 files in one of the two formats, you might have a chance of a successful summary. Note, however, there is no guarantee of success.
If you cannot find a usable backup or have difficulty restoring one, then you may have to move on to manual reconstruction as John has suggested.
The basis of this 2007 article is that you re-enter manually the price records.
My .qph file has 340,000 price records. I would not contemplate re-entering these manually, but the author of the article thinks that is a possible approach.
There should be a Reckon utility that converts any .qph file into a .csv file so that the records can be selected and imported. Some of us have developed such a utility.
Replacing a current database is rarely an acceptable option.
The following link explains the .csv file format that is very useful for importing the price records. This format can best be created in Excel, from a variety of sources, including third party .qph data extraction utilities.
The example posted is:
Omitted from the kb explanation of the extended price record example was:
RKN = Company_Code
2.34 = close_price
--- is a text field of --- ( presumably to identify not the date field )
2/2/12 = date as dd/mm/yyyy for pc with Australian date format.
--- is a text field of ---
2.36 = day_high
2.30 = day_low
150123 = Volume/100, so volume was 15,012,300 shares traded
* is a terminating text field
The "volume/100" value is now limited to 2,000,000 so sales up to 200 million shares are now possible. Previously it was limited to 200,000, ie 20 million shares which was not good for TLS shares.
How was the prediction of the Reckon share price of 2.34 on 2 Feb 2012 ?
There is also an abbreviated format which omits spread and volume:
This is good for non-traded companies, such as super funds or trusts.
